Executive Summary
In the course of 2005 the highly pathogenic Avian Influenza Asian lineage HPAI H5N1
virus spread from Southeast Asia to SW Siberia, Kazakhstan and the Southern Urals.
Migratory birds were suspected of playing a role in the spread of the disease. This meant
that the EU could be under direct threat as a number of waterbirds (geese, ducks and
shorebirds in particular) were known to migrate through the infected areas to the EU in
winter. The European Commission (DG Environment) therefore asked Wetlands
International and EURING to undertake the present study. The aims of the project were:
(1) to identify species which pose a relatively high risk of spreading H5N1 along their
migration routes to the European Union, (2) to analyse the migration routes of these so-
called Higher Risk Species on the basis of recoveries of ringed birds, (3) to identify
wetland sites where Higher Risk Species concentrate in large numbers during migration
and wintering and (4) to develop and test a format for the rapid assessment of
ornithological data at the level of wetland sites, in order to prepare wetland managers for
an outbreak of H5N1.
Identification of Higher Risk Species
The identification of Higher Risk Species focused on the Anseriformes (swans, geese and
ducks) and the Charadriiformes (shorebirds, gulls and terns), because these groups are
known to frequently carry Avian Influenza viruses. We first selected all species of both
groups which occur in Europe and which are migratory. Then each species was
characterized on the basis of behavioural and ecological characteristics which are
assumed to be related to the chance of becoming infected with H5N1 outside the EU. The
characteristics chosen were habitat use, gregariousness and degree of mixing with other
species. Species were selected which occurred in agricultural and/or freshwater habitats,
which were highly gregarious and which showed a high degree of mixing, which led to a
list of 26 Higher Risk Species being identified (Table 1.1). Contact risk with poultry was
also estimated, resulting in the highest scores for Mallard Anas platyrhynchos and Black-
headed Gull Larus ridibundus (Table 1.3).
In the discussion, “risk factors” are summarized for all Higher Risk Species (Table 1.6).
It is concluded that 13 of the 26 Higher Risk Species (50%) have been confirmed to be
infected with H5N1 (usually victims near outbreaks in poultry) against 8 out of 84 (9.5%)
of the non-selected species. This suggests that our selection has indeed identified
migratory bird species with a relatively high susceptibility to H5N1.
Concentrations and movements of Waterbirds with potential to spread Avian
Influenza
Waterbird count data from the Wetlands International IWC (International Waterbird
Census) database in Europe, Africa, West and Central Asia were analysed in detail,
together with data relating to birds ringed or found dead (recovered) in Europe and held
in the EURING databank. Numbers of 17 selected Higher Risk species in each EU
Member State during the breeding season and in January were also compiled and
presented. These data were supplemented by literature reviews. Detailed summaries of
sites holding important numbers of the 17 Higher Risk species are presented in maps and
6
Tables, and movements are summarised by means of monthly ring recovery maps,
generalised maps of migration patterns and migration synopsis Tables. Within Europe,
regions with particularly high concentrations of sites important for waterbirds in January
are the Black Sea-East Mediterranean region, the West Baltic and Southern North Sea
regions, and lakes north of the Alps. The West Mediterranean region is also important,
but key sites are more widely dispersed. Waterbird diversity is generally highest in
Eastern and Southern Europe, but sites with high numbers are found throughout the
continent except in mountainous regions and those that are frozen in January. There are
two large regions outside Europe but within the flyways of many of the 17 selected
Higher Risk species where very high numbers of waterbirds have been recorded: the
southern Caspian (particularly Azerbaijan) and western Iran, and the Sahel zone of West
Africa. Most of the Higher Risk species selected are broad front migrants which migrate
in westerly and southerly directions in autumn, and north and east in spring. April is the
month when most of these species move furthest on their spring migration. Autumn
migration is usually more protracted, beginning as early as July in some species, and
continuing until November for others. A number of key staging sites have been identified
in western Russia and Kazakhstan, but more information is needed on sites used during
migration.
Rapid assessment format for ornithological data in case of an outbreak of H5N1
Outbreaks of H5N1 among wild birds often occur unexpectedly, confronting site
managers with an emergency situation, which demands quick action. Managers, together
with local and national authorities will have to take decisions with respect to restricting
human use of a site, monitoring bird mortality and sampling for virus prevalence.
In order to give guidance to site owners and site managers to be prepared for an outbreak
of H5N1 in their wetland area, a format was developed for presenting ornithologcal
information (Annex 3.1). Its main purpose is to guide and stimulate site managers to
seriously consider possible future events, to prepare for an outbreak of HPAI, and to
develop a strategy in anticipation of the possible spread of the disease to their site.
The format developed includes:
- The nature of occurrence of vulnerable bird species
- Places with high concentrations of vulnerable bird species within the site
- Local movements of vulnerable bird species to neighbouring sites
- Position of site in flyway and consequences of bird movements for further spread of
H5N1
- Human use of the site and its disturbance effects
- The existence of poultry farms within a radius of 10 km of the site
- Measures to be considered in case of an outbreak
After the assessment format had been developed and guidelines for its use added, it was
tested for four sites:
- National Park Schiermonnikoog (Island in the north of the Netherlands)
7
- The Camargue (delta of the river Rhône in the south of France)
- Djoudj National Park (part of the delta of the Senegal river in the north of Senegal)
- Eastern Sivash (lagoons and lakes bordering the Sea of Azov, Crimea, Ukraine)
The assessments showed that a lot of information can be made available in a short period
of time. In reaction to the many questions posed in the format, site managers came up
with a large number of useful ideas. Of special interest was an analysis carried out in the
Sivash, aiming at identifying areas with different degrees of outbreak risk, based on three
factors: (1) the distribution of waterbird concentrations, (2) the distribution of human
habitation as a determinant of poultry density and (3) the distribution of small scale
waterways where wild birds and poultry can easily mix.

The waterbird count data which are the basis of the IWC database have been collected
over many decades by a large network of expert waterbird counters, most of whom are
volunteers. In Europe, at least 11,000 of these observers go out every year when the
weather is at its worst to count waterbirds as a contribution to their conservation. We
salute their expertise, enthusiasm and skill. We also thank over 100 National
Coordinators of waterbird monitoring schemes, without whom the IWC programme could
not function. Special thanks to Marc van Roomen, Johannes Wahl and Erik van Winden
who prepared summaries of national data at very short notice especially for this report.
We would also like to thank all the EURING schemes who work so hard to collect and
computerise the ring recovery data on which much of this report is based. We are
particularly grateful that so many schemes were able to send updated files of recoveries
to the EDB to allow this report to include the most recent information. The greatest
contribution to the collection of recovery data has been made by the thousands of bird
ringers, throughout Europe and elsewhere, who give their time to catch and ring wild
birds. Without these volunteers, work on this scale would be impossible. We would also
like to thank the many members of the public who have found and reported birds to the
ringing schemes. Again their contribution is invaluable.

Introduction
During 2005, the H5N1 strain of Highly Pathogenic Avian Influenza (HPAI) spread
north, then west from countries in east and southeast Asia that had been affected by the
disease since 1997. Factors causing the spread of HPAI include methods used in the
farming and transport of domestic poultry and poultry products, trade (legal and illegal)
in wild and domestic birds, and probably transfer between domestic birds and wild
migratory birds, especially a number of waterbird species. Knowledge of this disease,
although growing fast, is still limited and the relative importance of these factors is still
disputed, but there now seems little doubt that wild birds are capable of carrying the
disease and passing it on to other birds (Olsen et al. 2006).
As the disease spread, the serious consequences to public health, economic and
ecological interests gave HPAI a very high priority among national and international
decision makers. Outbreaks of the disease in west Asia, Africa and Europe were
predicted, and in late 2005 the European Commission initiated epidemiological,
virological and ornithological studies to find out about the occurrence and behaviour of
the disease in wild birds, and about the numbers, distribution and movements of wild bird
species which might pose a risk in its spread. This report is a summary and analysis of a
large volume of ornithological data collected over a number of decades by Wetlands
International (waterbird numbers and key sites) and EURING, the European Union for
Bird Ringing (waterbird movements). Data and information on bird numbers and
movements in Europe, southwest and central Asia, and Africa have been compiled and
analysed with the aim of assessing the risk at continental, national and site level of HPAI
spreading through the flyways of the birds that use these landscapes for breeding,
moulting, staging and “wintering”.
The report begins by identifying a suite of species which present a high risk of spreading
HPAI in Europe. This is followed by detailed analysis of numbers, distribution, key sites
and movements of 17 of these species. Work then focuses on four study sites used by
large numbers of these birds, which were used to develop an approach for rapid analysis
of relevant data at a site in the event of an outbreak of HPAI. Finally, the report identifies
gaps in information and proposes analyses that should be undertaken in continuation of
this work.

1. Identification of Higher Risk Species
1.1. Introduction
There is a wealth of information showing that Low Pathogenic Avian Influenza (LPAI)
viruses are widespread among wild birds, with a relatively high prevalence among
waterbirds, especially ducks. It is generally assumed that wild birds are the natural
reservoir for LPAI viruses which may occasionally infect free-range poultry in situations
where both make use of the same habitats. Galliform birds, such as chickens and turkeys
are especially vulnerable to AI viruses. Moreover, they are often kept in large numbers
and at high densities. Both these factors contribute greatly to the rate of virus replication
which, through mutation, may give rise to Highly Pathogenic Avian Influenza (HPAI)
strains. Wild birds may subsequently be infected with HPAI through contact with poultry.
The spread of HPAI from one area to another may result from movements of infected
poultry or poultry products as well as from movements by infected wild birds.
The outbreak of Asian lineage HPAI H5N1 which started in Hong Kong in 1997 first
spread into South East Asia and China, and subsequently, in 2005, westwards to Central
and Southwest Asia, and in 2006 to Europe, Africa and the Indian Sub-continent. The
way the virus spread has been the subject of much speculation. In a number of cases there
was clear proof that transport of poultry, poultry products or trade of infected pet birds
played a role. For a long period of time there was no proof of a role played by wild birds.
Nevertheless, there was a strong tendency to blame migratory wild birds, which was
especially apparent in the mass media. The recent spread of H5N1 over Europe has
clearly shown that wild birds do play a role in spreading H5N1: By the end of April 2006
there were outbreaks among wild birds in 13 European countries, whereas outbreaks also
occurred in poultry in only 3 of these countries.
Although wild birds play a role in the spread of H5N1, it should be stressed that any
detailed knowledge of the way in which this takes place is lacking. Despite the enormous
increase in interest of the scientific world in the mechanisms of spread of the H5N1 virus,
we still know very little about:
- The conditions under which H5N1 is transmitted between wild birds, either directly
through close contact, or indirectly through the environment;
- The length of incubation periods, course of the disease and virus shedding periods in
wild birds;
- Symptoms and mortality rates shown by diseased wild birds;
- Changes in behaviour of moribund birds, especially with respect to mobility and the
likelihood of carrying the virus over large distances;
- Whether wild birds may spread H5N1 mechanically, for instance by carrying faeces
on feathers and feet;
- Whether wild birds may carry H5N1 asymptomatically and transmit it to other birds.
11
The likelihood that a migratory wild bird species could introduce H5N1 into the EU and
that poultry could subsequently be infected requires the following conditions to be
fulfilled:
- The species visits an outbreak area.
- The species comes into contact with infected poultry and gets infected with H5N1, or
it comes into contact with infected material (faeces) which it then carries
mechanically.
- Infected individuals of the species are capable of migrating to within EU borders,
either being ill, or carrying the virus asymptomatically. Alternatively, infected birds
may transmit the virus to conspecific or heterospecific wild birds which may then
carry it to the EU.
- Within EU borders the species comes into contact with poultry. Alternatively, it
comes into contact with and infects other wild birds which function as “bridge
species” with respect to transmission of the disease to poultry.
Although we know very little about the mechanisms of spread of H5N1 in wild birds, the
above conditions can be related to a species’ behaviour and ecology. For instance,
migratory behaviour determines the chances of a species passing through outbreak areas
as well as the time spent in such areas. Habitat use can be expected to be largely
responsible for the chances that a species comes into contact with (free-range) poultry.
Behaviour patterns, such as the tendency to occur in large and dense groups and to mix
with other species can be expected to contribute to the likelihood that the virus is
transmitted from one bird to another. Once H5N1 has been introduced within EU borders,
behaviour such as the likelihood of occurrence near human settlements and of coming
into contact with poultry can be expected to be an important determinant for the infection
of poultry. Finally, the number of individuals present within a particular country or area
will contribute to the risk posed by “the species”.
This chapter deals with the identification of “higher risk species”, based on an analysis of
patterns of behaviour and ecology referred to above. The focus is on the introduction of
H5N1 to the European Union. Therefore, higher risk species are defined as bird species
which pose a relatively high risk (as compared to other birds) of spreading Highly
Pathogenic Avian Influenza (HPAI H5N1) along their migration routes from outbreak
sites outside the European Union to within EU borders.
1.2. Selection of Anseriformes and Charadriiformes for analysis
Altogether, some 500 bird species occur within the European Union, a large proportion of
them being migratory. As it was not feasible to analyse the behaviour and ecology of so
many species, a pre-selection had to be made. This was done on the basis of data on the
occurrence of Avian Influenza viruses in different taxonomic groups of birds.
In a large number of countries in all parts of the world, wild birds have recently been
analysed for the occurrence of Avian Influenza viruses. Data are available now for some
hundreds of different species. The proportion of individuals being infected with one or
12
more AI strains appears to vary with geographic location and with season, but differences
between species appear to be most prominent. Relatively high proportions of infected
birds have been found for the taxonomic groups of the Anseriformes (swans, geese and
ducks) and the Charadriiformes (waders, gulls, terns and auks) whereas far lower
proportions (often equal or near to zero) have been found for nearly all other taxonomic
groups (Kaleta et al. 1985, Webster et al. 1992, Alexander 2000,). The above mainly
refers to Low Pathogenic Avian Influenza viruses (LPAI). Data on the occurrence of
HPAI strains in wild bird populations are extremely scarce. This also applies to H5N1,
which has only been found in a few cases and in extremely small numbers in virtually
healthy wild birds (e.g. Tree Sparrow, Kou et al. 2005). However, victims of H5N1
(usually birds found dead) have been recorded in most areas where outbreaks of H5N1
have occurred. Many of these victims appeared to belong to the Anseriformes and
Charadriiformes as well (for updated overviews see USGS 2006).
Considering the above, we conclude that there is a clear prevalence of Avian Influenza
viruses in the Anseriformes and Charadriiformes. This has led to the decision to consider
for the present analysis all species belonging to the Anseriformes and the
Charadriiformes, which occur in Europe and which are migratory in the sense that (a
substantial part of) the population migrates from outside the EU to within EU borders.
Altogether 110 species were listed in a spreadsheet after which behavioural and
ecological characteristics were noted as will be outlined below. The full spreadsheet is
given as Annex 1.1
1.3. Selection of higher risk species on the basis of behaviour and ecology
Migratory wild birds being infected with H5N1 outside the European Union might
introduce the disease within EU borders in a direct as well as an indirect way. In the first
case it is assumed that the infected bird itself migrates to the EU, whereas the second
possibility implies that other birds are infected along the migration route, which then
bridge the gap to the EU. In this respect the following behavioural and ecological factors
are considered important determinants for the acquisition and transmission of the HPAI
virus:
- habitat use during migration/wintering
- gregariousness during migration/wintering
- degree of mixing with other species during migration/wintering
1.3.1. Main habitat during migration and wintering
Habitat is assumed to be of importance with respect to the chances of a species becoming
infected with the H5N1 virus outside the EU. There is currently little evidence to support
this assumption, although it is reasonable to assume that a species occurring solely at sea
or in the forest canopy poses considerably less risk of coming into contact with poultry
(and becoming infected) than a species that uses agricultural habitats also frequented by
free-range poultry.
13
Habitat use is also assumed to influence the chances for wild bird to wild bird
transmission. Apart from the possibility that the virus is transmitted through direct
contact or through the air, birds may also be indirectly infected through the environment.
Since Avian Influenza viruses appear to survive better in water than on land, and fresh
water gives better survival rates than salt water (Stallknecht pers. com.), it can be
expected that indirect infection takes place relatively easily in fresh water habitats.
For each species, habitat use has been indicated using the following coding:
A = agricultural land
N = natural land habitat (usually marshes near wetlands; this coding has
especially been used to distinguish purely freshwater species, which
rarely come ashore (F), from those which also use non-agricultural land
habitat (FN))
O = other land habitat (variety of habitat types, including woodland and urban
areas)
F = fresh water
M = marine
L = littoral
Where more than one habitat is used, multiple coding has been applied. Note that the
sequence of habitat code elements indicates relative use of the different habitats. Thus the
code MF indicates that the species primarily occurs in marine areas but also can use
freshwater habitats, whilst FM would indicate the converse.
The various codes used are as follows: AN, AL, F, FA, FAL, FAN, FL, FLN, FM, FN, L,
LA, LF, LFA, LFN, M, MA, MF, ML, O.
1.3.2. Gregariousness during migration/wintering periods
Little information is available showing a relationship between gregariousness and the
chances of Avian Influenza viruses being transmitted between birds (but see Deibel et al.
1985). Expert opinion and basic epidemiological principles suggest that species which are
highly gregarious are more likely to become infected with H5N1 since close contact
between birds may result in the virus being more readily passed from bird to bird within
flocks. Two components of gregariousness can be assessed, group size and group density.
Gregariousness has been indicated by two letters, which denote group size and group
density, respectively. The following coding has been applied:
Group size
L = Large: often several hundreds to thousands of individuals (Eurasian
Wigeon Anas penelope)
M = Medium: often several tens to few hundred individuals (Whooper
Swan Cygnus cygnus)
S = Small: often up to a few tens of birds (Purple Sandpiper Calidris
maritima)
O = Usually solitary or a few birds together (Green Sandpiper Tringa
14
ochropus)
Density
H = High density: often less than 2 m between individuals (Dunlin Calidris
alpina)
M = Medium density: often 2-5 m between individuals (Herring Gull Larus
argentatus)
L = Low density: often more than 5 m between individuals (Common
Snipe Gallinago gallinago)
O = (near) solitary (Great Skua Stercorarius skua)
1.3.3. Degree of mixing during migration/wintering periods
Species which readily mix with other species of waterbirds are thought to be more likely
to become infected with H5N1, since contact between species may result in transmission
of the viral infection. Likewise, it is assumed that species which do not come into close
contact with other species are at lower risk of infection. The mechanisms of spread
between species are assumed to be largely similar to those between individuals within
flocks of the same species. As with gregariousness, there is currently no evidence to
support these assumptions.
Degree of mixing with other species (mixed foraging, mixed roosts, mixing at moulting
areas, etc.) has been indicated as follows:
H = High degree (Eurasian Wigeon Anas penelope)
M = Medium degree (Northern Lapwing Vanellus vanellus)
L = Low degree (Temminck’s Stint Calidris temminckii)
O = Hardly any mixing (Common Sandpiper Actitis hypoleucos)
1.3.4. Analysis
Taxa were analysed at the species level with one exception: the Greenland race of the
Greater White-fronted Goose Anser albifrons flavirostris was evaluated separately on the
basis of significantly smaller group sizes and lower degree of mixing compared to the
nominate race A.a. albifrons which largely occurs on continental Europe.
Higher risk species
Referring to the above, species which prefer agricultural fields and freshwater habitats,
which are gregarious and have a high degree of mixing with other species, should be
regarded to pose the highest risk of spreading H5N1 from outside the EU to within EU
borders. In evaluating such species, a number of steps were taken.
Species were not selected if:
- They occurred mainly in marine (M), littoral (L), environments or other habitats (O)
(i.e. species whose habitat use codes begin with O, L or M since such species are
expected to only occasionally use freshwater and agricultural habitats, and/or
15
- They showed hardly any, or a low gregariousness (i.e. codes denoting small group
size (O and S) in combination with low and medium density (L and M). In Annex 1.1
these are the codes OO, OL, OM, SL, and SM), and/or
- They showed least mixing with other species (showing either hardly any mixing (O)
or a low degree of mixing (L)).
The resultant selection of higher risk species on the basis of habitat use, gregariousness
and degree of mixing is given in Table 1.1. It consists of 2 swan, 8 goose, 10 duck, 4
shorebird and 2 gull species (total 26 species).

1.4 Higher risk species in relation to the source of an outbreak
The higher risk species selected above can be expected to pose a risk only if they pass
through outbreak areas where they can potentially be infected with H5N1. At the time
this project was developed, the nearest outbreak areas occurred around the Black and
Aegean Seas and in the Southern Urals. This has led to an analysis of migratory
behaviour focussing on these two areas.
For each species included in the analysis (see Annex 1) the following questions were
asked:
- Does the species have a well-defined migratory flyway?
- Is there a potential direct migratory linkage between the Black or Aegean Seas and
the EU?
- Is there a potential direct migratory linkage between the Southern Urals and the EU?
No attempt has been made to analyse the migration behaviour in relation to other
(potential) outbreak areas. An exception has been made for higher risk species migrating
through Nigeria, just to show that different sub-sets of the list of higher risk species
should be considered depending on geographic location of outbreak areas (see Table 1.2).

1.5 Higher risk species and contact risk with poultry within the EU
All higher risk species identified migrate to the EU in large numbers, many of them
staying within EU borders for most of the winter. It has been argued that habitat use,
gregariousness and degree of mixing can be expected to play a major role in the chances
of a species getting infected with H5N1 along its migration route and subsequently
introducing it into EU countries. The same aspects of behaviour and ecology can be
expected to play an important role in further spreading the virus within Europe, between
wild birds as well as back to poultry.
Although contact risk with poultry is regarded as being at least partly incorporated into
the factor habitat use, it was felt necessary to study this factor in more detail for the
European situation. On the basis of knowledge of the behaviour of waterbirds, the
likelihood of close contact between the species listed in Table 1.1 and
domesticated/captive poultry has been assessed as:
H = High contact risk
M = Medium contact risk
L = Low contact risk
O = Virtually no contact risk
This assessment has considered risk as a function of contact intensity. Thus a scenario
where small numbers of wild birds are potentially in contact with poultry for a long
period is considered equivalent to a scenario where larger numbers are in contact for a
shorter period. Independent assessments of risk were sought from the members of the
Scientific Working Group of the EC Birds Directive’s Ornis Committee. Data were
obtained from the representatives of the United Kingdom, Ireland, Portugal, Czech
Republic, Slovenia, Austria, Germany, The Netherlands and Estonia who all provided
data, based on expert judgement, for the situation in their own country. Mean scores
calculated are given in Table 1.3. (The Table includes only the data for the HRS species;
for other species see Annex 1.1)
Table 1.3: Indication of contact risk with poultry for higher risk species based on data obtained from nine
EU member states (results of a questionnaire presented to the Scientific Working Group of the EC Bird
Directive’s Ornis Committee). Contact risk is given as: H = high, M = medium, L = low, O = virtually
impossible.

Contact risk with poultry through bridge-species
Contact between wild birds and domestic poultry is likely to be restricted to species, not
exclusively waterbirds, that associate with man, for instance by looking for food provided
for poultry or simply by being associated with farmland. Birds that live in close proximity
to domestic poultry can be considered as “bridge species” in having the potential to
transmit H5N1 from wild waterbirds, higher risk species in particular, to poultry.
Representatives of a large number of taxonomic groups might act as bridge species in the
European situation, a tentative list of the most likely species being given in Table 1.4. It
should be noted that bridge species have not been subject of this study. The list should
therefore be treated with caution. It has been compiled to serve as an example for the
rapid assessment of ornithological data for wetlands sites in case of an outbreak of H5N1
as described in Chapter 3.

1.6 Abundance of higher risk species within the EU
The threat posed by a particular bird species with respect to the risk of introducing and
spreading H5N1 in the EU (and similarly in each individual country) can be expected to
be related to the number of individuals of that species entering the EU and the length of
its stay. Table 1.5 gives the size of the non-breeding biogeographic populations
established for populations within boundaries which include Europe (data according to
Wetlands International 2002). It shows marked differences, with numbers varying
between 8,000-10,000 (Lesser White-fronted Goose) and 6,900,000-9,000,000 (Black-
headed Gull) individuals. Breeding and wintering populations for the different member
states are given in Tables 2.2 and 2.5 in the next chapter.

1.7 Discussion
In the preceding sections, an analysis was made of the relative risk posed by migratory
wild bird species belonging to the taxonomic groups of the Anseriformes and
Charadriiformes of introducing and subsequently spreading H5N1 within Europe. A list
20
of 26 higher risk species was identified on the basis of aspects of behaviour and ecology
which are assumed to determine, at least to a large extent, the chances of becoming
infected with H5N1 outside EU borders. The assessment of behaviour and ecology has
largely been done on the basis of expert judgement and the question arises whether there
is any indication that our selection indeed represents species which are more likely to
carry H5N1 than others? It has been mentioned before that the number of cases in which
H5N1 has been found in apparently healthy birds is extremely small. However, there is
an ever increasing number of birds found dead in areas with outbreaks of H5N1 for which
infection with the virus has been confirmed. Such victims, apart from two cases all found
dead, can be regarded as representing species which have a relatively high chance of
coming into contact with infected poultry. Considering the list of H5N1 infected species
(data available up to 30 March) it appears that 13 out of 26 (50.0%) higher risk species
have been found against 8 out of 84 (9.5%) of the non-selected species. This large
difference in H5N1 prevalence leads us to conclude that the higher risk species are indeed
more likely to be infected with H5N1 than the non-selected species.
Table 1.6 gives an overview of the various risk factors considered. Within each column
relative risk is expressed by a number of crosses. It appears that differences with respect
to behaviour and ecology are relatively small (species were all selected because of their
high scores!) but there are major differences for contact risk with poultry (from zero to
XXX) and species abundance (X to XXXXXXXX). Mallard and Black-headed Gull
show high scores for all risk factors.
The risk factors included in Table 1.6 can all be expected to play a role in the spread of
H5N1 once it is introduced within EU borders. However, the various factors do not
simply add up as they are interrelated in several ways. For instance, habitat use is
assumed to influence contact risk with poultry, whereas gregariousness can be expected
to show some relation to population size (numbers in Table).
The identification of higher risk species and the attribution of risk factors as given in
Table 1.6 refers to the EU as a whole. There are, undoubtedly, marked differences
between EU member states and, even more pronounced, at the level of wetland sites. As a
consequence, the data presented here should always be “translated” to the local situation.
First of all, higher risk species are not evenly distributed over the EU member states. For
instance, 80% of all wintering Greater White-fronted Geese winter in the Netherlands and
Germany, more than 90% of all Red-breasted Geese winter in Bulgaria, Romania and
Greece, whereas nearly all European wintering Marbled Teal concentrate in Spain.
Contact risk with poultry is also a factor to be considered with great caution and to be
looked at at a national or local scale. First of all, the mean scores provided for this factor
are based on data available for only 9 EU member states. Moreover, it should be noted
that on many occasions contact risk assessed for a particular species was markedly
different between countries. Such differences might be related to a variety of factors such
as local differences in poultry keeping methods and factors such as food availability and
disturbance. Chapter 3 gives some more information about how ornithological data could
be analysed and used in order to be prepared for outbreaks of H5N1 at a local scale.

H5N1 indicated (right hand column). Risk is indicated with a number of crosses in the following ways:
Ecology and behaviour (maximum score XXXX): one X has been given for F and A in habitat use, MM or
higher in gregariousness and M or H in degree of mixing. Contact risk with poultry (maximum score
XXX): L, M and H have been given X, XX and XXX, respectively. Numbers in EU (maximum score
XXXXXXXX): each X stands for 1 million birds (rounded figures for wintering population) with the
exception that one X also includes population sizes smaller than 500,000 (numbers refer to bio-
geographical winter populations as used in Table 1.5). For information on the meaning of codes used, see

The primary aim of our analysis was the identification of species which pose a relatively
high risk of spreading Highly Pathogenic Avian Influenza (HPAI H5N1) along their
migration routes from outbreak sites outside the European Union to within EU borders.
We have restricted our analysis to the bird orders of the Anseriformes and
Charadriiformes. This choice was based on the prevalence of Avian Influenza viruses in
both groups. Moreover, nearly all representatives of these groups are waterbirds, most of
which migrate over long distances. This made them highly appropriate for our study.
However, it should be stressed that there are other species, migratory as well as
sedentary, which might qualify for the status of higher risk species with respect to the
22
spread of Avian Influenza. Of special interest are waterbirds of the following families:
Podicipedidae (grebes), Phalacrocoracidae (cormorants), Ardeidae (herons and egrets),
Ciconiidae (storks), Threskiornithidae (ibises and spoonbills), Phoenicopteridae
(flamingos) and Rallidae (coots). Besides, attention should be given to predators,
scavengers and opportunistic feeders represented by the following families: Accipitridae
(hawks, vultures and eagles), Falconidae (falcons), Corvidae (crows), Sturnidae
(starlings) and Passeridae (sparrows).

2. Concentrations and movements of
waterbirds with potential to spread
Avian Influenza
2.1 Introduction
2.1.1 Waterbird numbers, distribution and key sites
The International Waterbird Census (IWC), Coordinated by Wetlands International and
its predecessor organization, IWRB, was established in Europe and West Asia in 1967
and in Africa in 1990. Every year in January, over 20 million waterbirds are counted in
the Western Palearctic, and up to 10 million in Subsaharan Africa by a network of about
14,000 largely voluntary waterbird counters (Gilissen et al. 2002, Dodman & Diagana
2003). The use of standardized methods and recording forms and modern computer
software ensures that a continental-scale time series of data on waterbird numbers,
distribution and population trends is available as the scientific basis of waterbird
conservation (e.g. Wetlands International 2002, 2005 Delany et al. 2005). Counts are
conducted in January because this is when many waterbird species congregate
conspicuously at a relatively small number of sites where they can be readily counted.
The January count is supplemented in Subsaharan Africa by a second annual count in
July, and there are plans for additional counts throughout Europe, Africa and Asia, in
March-April and September-October, to collect information from sites important during
migration.
2.1.2 Interpretation of IWC data
More than 100 countries now participate in IWC around the world. The Census is
coordinated at National Level by a wide variety of organisations and institutes and there
are differences in approach which should be borne in mind when interpreting the
resulting count data. The census is site-based, and defining sites in a standard way is
problematic. Conservation policy uses criteria such as “sites that have held more then
20,000 waterbirds” or “sites that have held more than 1% of a waterbird population”, but
criteria for defining sites are rather general and open to interpretation. In this report,
many tables are presented which show sites where high numbers of waterbirds have been
counted. It should be remembered when using these tables that site definition procedures
are not totally objective. An example of this is the Inner Niger Delta in Mali, a wetland
whose size varies according to flood conditions, but is, in some seasons, approaching the
size of a small European country such as The Netherlands. For the purposes of the
Census, this site has been divided into numerous quadrats, and data are presented on this
basis, although treating the entire area as one very large “site” might be justified.
It should also be borne in mind that IWC totals are nearly always under-estimates of
actual numbers of birds present in a site or a country. No country can cover 100% of
suitable habitat, and site-based methods do not allow meaningful extrapolation. The IWC
24
totals are thus affected by levels of count coverage achieved at each site and in each
country. Great efforts are made to standardise coverage from year to year, and most
European countries now achieve high levels of coverage every year. Coverage in West
Asia and Africa is less complete, but the most important sites in most countries have been
covered between 1990 and 2005, the period covered by this report.
2.1.3 Final list of Higher Risk species for which detailed analyses were undertaken
For detailed analysis of numbers, distribution and movements 15 of the 25 “Higher Risk”
species identified in Table 1.1 above were selected for analysis, plus two of the “near-
selected” species also identified in Chapter 1.
The final list of species selected for these analyses is as follows:
Mute Swan
Cygnus olor
Greater White-fronted Goose
Anser albifrons
Greylag Goose
Anser anser
Red-breasted Goose
Branta ruficollis
Eurasian Wigeon
Anas penelope
Gadwall (“near-selected”)
Anas strepera
Common Teal
Anas crecca
Mallard
Anas platyrhynchos
Northern Pintail
Anas acuta
Garganey
Anas querquedula
Northern Shoveler
Anas clypeata
Red-crested Pochard
Netta rufina
Common Pochard
Aythya ferina
Tufted Duck
Aythya fuligula
Northern Lapwing
Vanellus vanellus
Black-headed Gull
Larus ridibundus
Black Tern (“near-selected”)
Chlidonias niger
It was agreed that with the time available for this “preliminary analysis” it would be
possible to undertake detailed analyses of numbers, key sites and movements of about 15
species. Species from the final list of “Higher Risk” species identified above on the basis
of their habitat use, gregariousness and degree of mixing were not included if data quality
were considered to be relatively poor, or if the data were in a form which could not be
readily analysed. The waterbird count data for geese are collected, stored and analysed
separately from the rest of the International Waterbird Census database, and for this
reason, only three of the geese were included. Similarly, the count data for most species
of gull are incomplete and Larus canus was excluded for this reason. The geese included
were the two most widespread in Europe (Anser albifrons and Anser anser) which make
extensive use of farmland, plus a scarce species (Branta ruficollis) an individual of which
25
died of HPAI in Greece in 2005. Cygnus columbianus and Marmaronetta angustirostris
were excluded because of their scarcity and their restricted distributions in Europe.
Finally, waders (shorebirds) may be less susceptible to HPAI than Anseriformes, gulls
and terns, and Eurasian Golden Plover, Ruff and Black-tailed Godwit were excluded for
this reason, leaving one species, Vanellus vanellus to represent this group. Two species,
Gadwall Anas strepera and Black Tern Chlidonias niger were included in detailed
analyses although they only qualify as “near-selected in the analysis undertaken in
Chapter 1. Gadwall is the one widespread European dabbling duck otherwise excluded,
and Black Tern has a more extensive non-breeding range in Africa than any other Higher
Risk species.
2.1.4 The count data presented
The analyses presented in this report have been undertaken on behalf of the European
Commission, specifically as an “urgent preliminary assessment”. The best available data
have been used to summarise numbers, distribution and movements of 17 species
considered to present a High Risk of spreading Avian Influenza. The data presented for
some species, particularly the geese, Northern Lapwing, and Black-headed Gull, were
collected from a less standardised set of sites than those for other species, because of the
particular way these species use the landscape (geese, which feed in fields by day and
roost at wetlands at night), and because of differences in approach for different taxa in
some countries (data for waders are submitted separately in The Netherlands, counting of
gulls remains optional in some countries).
Waterbird count data presented in this chapter are thus biased towards counts made in the
month of January, because of the implementation of IWC as the “midwinter census”.
Additional information on important breeding, moulting and staging sites in countries of
the former Soviet Union has been extracted from the Russian literature (Table 2.1), but a
comprehensive literature review of such sites in the rest of the region included in this
report has been beyond the scope of contracted work.
Table 2.1: Publications in the Russian literature consulted to supplement data from the International
Waterbird Census in analyses of important sites for waterbirds. The identification numbers in the table
below are the same as those used in the tables of summarised count data to identify sources of information.

This chapter starts with a review of numbers of 17 of the Higher Risk species identified
in Chapter 1 in European Union Member States in the Breeding and non-breeding
seasons. Four general analyses of site importance for Higher Risk waterbird species in
Europe, west and Central Asia and Africa are then presented, showing: 1. Sites where
high numbers of all waterbird species have been counted; 2. Sites where high numbers of
the 17 Higher Risk species have been counted; 3. Sites where a high diversity of the 17
Higher Risk species occur together and have the opportunity to mix; and 4. Sites that hold
both high numbers and a high diversity of the 17 example Higher Risk species. Because
of outbreaks of HPAI in 2005-2006 in Russia, Central and Southwest Asia and Africa,
within the flyways of many waterbird species that migrate to Europe, data from these
regions are included in these analyses. This general section is followed by an Introduction
to the data derived from Bird Ringing. 17 species accounts follow, which include a map
and a table summarising the count data for each Higher Risk species, and maps and tables
summarising the ring recovery data.
2.2 Summary of numbers of Higher Risk species in EU member States and Russia
2.2.1 Breeding Season
Table 2.2 is a summary of estimated numbers of breeding pairs of each of the 17 Higher
Risk species in 24 EU member states. With a few exceptions, these data were compiled
by BirdLife International (2004). None of the Higher Risk species were recorded as
breeding in Malta. The numerical range presented for each species is the estimated
number of breeding pairs (minimum to maximum estimates) compiled from national

sources by BirdLife experts in each country. The table also includes the estimated
number of breeding pairs of each of these species in European Russia because of the
outstanding importance of this country for waterbirds in the breeding season. Most
species breed in even higher numbers east of the Urals than in European Russia, but data
are incomplete and accurate totals are very difficult to estimate.
From Table 2.2, the importance of each EU member state as a breeding area for Higher
Risk waterbird species can be ranked as presented in Table 2.3. The maximum estimate
from each country in BirdLife International (2004) has been used to compile the table.

The number of pairs of the 17 Higher Risk waterbird species estimated to breed in each
member state of the EU is strongly affected by the latitude and longitude of the country
and by the availability of suitable habitat. For most species, countries in northern and
eastern Europe are closer to the core of the breeding range in Russia and these countries
hold relatively high numbers in the breeding season. Examples of such important
countries in northern and eastern Europe are Finland, Poland, Sweden Denmark and the
Baltic states. The importance of The Netherlands, Germany and the UK can be explained
by their importance for the three most numerous Higher Risk species in the EU: Mallard,
31
Black-headed Gull and Northern Lapwing. EU member states in southern Europe hold
relatively small numbers of Higher Risk species in the breeding season, and Cyprus,
Greece, Portugal and Italy are all near the bottom of Table 2.3, Even Spain and France,
relatively large countries, are below much smaller countries further to the north and east
such as Denmark, Lithuania and Estonia.
The number of Higher Risk species breeding in European Russia is included in Table 2.2
and for all species combined is roughly the same as the number estimated to breed in all
EU member states combined. In fact, only four species are estimated to have higher
breeding populations in all EU member states combined than in European Russia:
Mallard, Black-headed Gull, Greylag Goose and Mute Swan. The freezing in winter of
most of Russia and other countries in eastern and northeastern Europe is the driving force
behind migration patterns of waterbirds east and south into the rest of Europe, Africa, the
Middle East and beyond.
The number of each Higher Risk species breeding in the 25 EU countries can be ranked
and summarized from Table 2.2 in a similar way (Table 2.4).

The most numerous Higher Risk species found in EU states in the breeding season is
Mallard, and other very numerous species (more than one million counted) are Black-
headed Gull and Northern Lapwing. 12 of these species are present in the European
Union in the breeding season in only modest numbers (fewer than 125,000 pairs)
32
reflecting the preference of a majority of Anatidae species to breed further north and east
in Russia (see Table 2.2 for estimated totals breeding in European Russia).
2.2.2 Non-breeding season
Table 2.5 is a summary of peak national totals of Higher Risk species in the 24 EU
member states that contribute to IWC (the one non-contributing state is Malta, which
holds very few waterbirds). The number presented for each species is the highest total
obtained by summing all January counts from all sites in each country in each year
between 1990 and 2005. In most countries, the seventeen Higher Risk species represent
about half of the waterbirds counted in January each year. It should be remembered that
counts are always an under-estimation of actual numbers, since a certain proportion of
every species is missed by the January counts. This proportion is highest in species with
a dispersed winter distribution and those with inconspicuous behaviour.
From Table 2.5, the importance of each EU member state as a wintering area for Higher
Risk waterbird species can be ranked as presented in Table 2.6.

The number of Higher Risk waterbirds counted in each member state of the EU in
midwinter is roughly proportional to the area of the country, with a number of notable
33
exceptions. The Netherlands, The UK, Denmark, Ireland and Greece are relatively small
countries with disproportionately high numbers of wintering waterbirds. This is because
of the large numbers of wetlands in these countries, all of which have long coastlines, and
are situated outside, but not very distant from, the normal zone of January freezing of
wetlands. Sweden, Poland and Finland hold fewer waterbirds in winter than their
geographical area might be expected to support, but all three countries are affected
heavily by January freezing of wetlands.
The number of each Higher Risk species wintering in the 25 EU countries can be
summarized from Table 2.5 in a similar way (Table 2.7).

The most numerous Higher Risk species found in EU states in winter (as in the breading
season) is Mallard, and other very numerous species (more than one million counted) are
diverse, including a goose, a dabbling duck, a diving duck, a wader and a gull. Three of
these species are present in the European Union in winter in very low numbers: Red-
breasted Goose (most of which winter on the Black Sea coast of Bulgaria, Romania and
Ukraine), Garganey and Black Tern (both of which largely winter in Subsaharan Africa).

2.3 Summary of combined counts of all waterbird species
Figure 2.1. and Table 2.8 summarize the results of the International Waterbird Census
(IWC) for all the approximately 220 species included in Europe, North Africa, West
and Central Asia. Site totals presented on the map and table were compiled by
summing the peak counts of each waterbird species at each site in the period 1990-
2005, regardless of the year in which the peak count of each species was made. No
appropriate data were available from sub-Saharan Africa for this analysis.
It should be remembered that many species in addition to the 17 selected for detailed
analysis carry a risk of catching and spreading Avian Influenza, and that all sites
holding large numbers of waterbirds have the potential to act as significant reservoirs
of the disease. This map and table thus include sites of high relevance to the spread of
Avian Influenza in Europe.
Sites recording high January counts of waterbirds are spread throughout the region,
but the sites holding the very highest numbers are mostly in West and Central Asia.
One site, Big Kyzyl Agach (Gyzylagach) Bay in Azerbaijan, has a site total of well
over one million waterbirds and three further sites have totals exceeding half a
million, two of which are also in Azerbaijan and the third in Iran. Of the 91 sites in
this region detailed in Table 2.1 that have held more than 100,000 waterbirds, 50
(55%) are in Europe. Of the 17 sites with totals higher than 250,000, however, only
five are in Europe. These are The Danish Wadden Sea, The Crimea region (Sivash),
Ukraine, The Wash (UK), Shabla Lake (Bulgaria) and Skadar Lake (Serbia &
Montenegro-Albania).
The bias in distribution of important sites for wintering waterbirds in Central and
West Asia and the Black Sea/East Mediterranean region reflects the breeding
distribution of a high proportion of these birds in Russia, from where they migrate
south and west each autumn in response to freezing weather. Movement to Central
and Western Europe and to Africa involves a longer migration, a strategy adopted by
large numbers of birds, but fewer than those migrating the shorter distances to Central
and West Asia and the Black Sea/East Mediterranean region.
Table 2.8: Peak January site totals between 1990 and 2005 of all waterbird species combined, at
sites covered by the International Waterbird Census in Europe, West and Central Africa. The
peak counts of each waterbird species at each site in this period have been summed to produce site
totals. All sites where totals of 60,000 or more have been recorded are shown. No appropriate data are
available for sub-Saharan Africa.

2.4 Summary of combined counts of 17 selected Higher Risk waterbird species
Figure 2.2 and Table 2.9 present IWC results of combined January counts of waterbird
species at sites similar to those in Figure 2.1 and Table 2.8, but only including the subset
of 17 species selected as Higher Risk species for detailed analysis. There are similarities
between the results, and the inclusion of data from Africa reveals the particular
importance of the Sahel zone of West Africa for some of these species. This subset of
species also appears to make less use of coastal sites than all waterbird species combined,
and this is likely to be a reflection of the large numbers of waders (shorebirds) that
feature in the IWC data but represented by only one species, Northern Lapwing, in the
Higher Risk species.
41
The inclusion of data from the Russian literature and from the African dataset of the IWC
for these species gives a more complete picture of important sites than was possible for
all waterbird species combined from the IWC data alone (Figure 2.1, Table 2.8). West
and Central Asia and the Black Sea/East Mediterranean again feature strongly as holding
a high number of the most important sites. Of the 10 sites holding more than 250,000 of
these 17 “Higher Risk” species, two are in Russia, two in Azerbaijan, two in Iran, and
one each in Kazakhstan, Bulgaria, Senegal and Mali. Of the 58 sites in this region
detailed in Table 2.9 that have held more than 50,000 Higher Risk waterbirds, 32 (55%)
are in Europe. Of the 10 sites where more than 100,000 Higher Risk waterbirds have
been counted, however, only two are in Europe: The Shabla Lake complex in Bulgaria,
and the Neman River Delta in Russia.
Table 2.9: Peak January site totals between 1990 and 2005 of 17 waterbird species considered to pose
a High Risk of spreading Avian Influenza in Europe, Africa, West and Central Asia. The peak counts
of each Higher Risk waterbird species at each site in this period have been summed to produce site totals.
All sites where peak count totals of 40,000 or more have been recorded are included.

2.5 Summary sites where high number of Higher Risk waterbird species mix
Figure 2.3 and Table 2.10 show sites where high numbers of “Higher Risk” species mix
in January. Sites where more than 100, 250 or 500 of two or more “Higher Risk” species
have been recorded during IWC counts since 1990 are shown on the map. For most
species, sites are only included on the map if more than 500 birds have been counted, but
for less numerous and more dispersed species, lower thresholds have been used, as
follows: Mute Swan 250, Greylag Goose 250, Northern Pintail 250, Northern Shoveler
250, Gadwall 100, Black Tern 100. All sites holding two or more of these species in these
numbers are shown on the map, and those holding 7 or more species in these numbers are
included in the table.
47
Table 2.10: Sites that have held seven or more of 17 waterbird species considered to pose a High Risk of
spreading Avian Influenza between 1990 and 2005 in Europe, Africa, Middle East and Central Asia All
sites where seven or more species have been recorded in numbers exceeding 100, 200 or 500 (see text) are
included.

2.6 Combined data: sites important for large numbers of birds and a high variety
of species
Analyses of sites important for large numbers of waterbirds in winter (2.3, 2.4), and those
important for a wide variety of species (2.5) resulted in rather different lists of important
sites. An analysis was therefore undertaken where these two factors (numbers and
diversity) were combined. Figure 2.4 and Table 2.11 include sites where two or more of
the 17 Higher Risk waterbird species have been counted in numbers exceeding certain
thresholds between 1990 and 2005. For most species, the threshold above which sites
were included on the map was set at 500, but for less numerous and widespread species
lower thresholds were used, as follows; 250 for Mute Swan, Greylag Goose, Gadwall,
Northern Pintail, Northern Shoveler, and 100 for Black Tern. These are the same
thresholds used to identify important sites for each species in the species accounts which
52
follow. Selection on this basis produced a list of sites, which are shown in Figure 2.4.
Table 2.11 includes all 487 such sites where more than 20,000 waterbirds of two or more
species have been counted in these numbers. This table provides a good starting point for
compilation of a definitive list of sites posing a High Risk of transmission of HPAI in the
event of outbreaks among wild birds.
53
Figure 2.4: All sites where combined counts of “Higher Risk” waterbird species exceeded 20,000 between 1990 and 2005, and where two or more of
these species occurred in numbers exceeding thresholds of 100, 250 or 500, (depending on species – see text).
54
Table 2.11: All sites where combined counts of “Higher Risk” waterbird species exceeded 20,000,
between 1990 and 2005, and where two or more of these species occurred in numbers exceeding
certain thresholds (see text).

2.7 Species Accounts
For this preliminary analysis, 17 Higher Risk waterbird species were selected as
described above. For each of these species, the January count data held in the IWC
database were queried, and additional information on sites important for breeding,
moulting and wintering were compiled from the Russian literature and added to the
dataset (for more details, see the Introduction and Table 2.1). These data are summarized
on maps and important sites for each species are presented in tables. The tables include
columns for country, site name, peak count and year of peak count. These are followed
by a type” column indicating the type of count by codes, as follows: J: January count;
M: Count of moulting concentration; S: count at a staging area on migration; B: Count at
breeding site. The Reference column in the tables gives a reference number for the source
of information, as listed in Table 2.1
The second section of each species account gives details about the migration patterns of
the species, based on ring recovery data, and the following Introduction gives information
necessary for the correct interpretation of the migration data.
2.7.1 Waterbird movements
The second section of each of the Species Accounts gives information on the movements
of these 17 species of waterbird considered to be at risk of contracting and spreading
Avian Influenza (AI) by migratory movements. For each species, the following
information is presented:
An overview of the migratory movements
A summary map showing the movements of each species. These maps are based on
published information that has been interpreted by ornithological experts and
therefore give an impression of the movements of birds.
A table providing details of migratory movements gathered from the literature and
ringing recoveries.
A map of the areas with the highest wintering concentrations of each species
Dot maps giving finding locations (recoveries) of birds ringed in Europe,
accompanied by maps giving sample sizes (see below).
A set of maps for each species from country atlases either published or in preparation
to provide further background information, which is provided in Annex 2.2.
64
The information presented in the dot maps of finding locations is based on reports of
ringed birds (recoveries). The data have been generated by ringing schemes throughout
Europe, and are held in the EURING databank (EDB), currently hosted by the British
Trust for Ornithology (
www.euring.org). Ringing schemes throughout Europe have both
volunteer and professional ringers who have generated these data. The data are submitted
to the EURING databank to provide a single access point for recovery information for
Europe.
2.7.1.1 Biases in the collation of ring recovery data
The dot maps provide a straightforward method of describing the distribution of a species
and thus providing information about their movements. Finding locations are presented
for each species. An initial map shows all recoveries and is followed by monthly maps to
show the distribution of that species throughout the year. For Red-breasted Goose there
are only four recoveries and these are presented on one map that shows the location and
the month of finding.
The different types of recoveries can introduce biases into the data. Those birds
recaptured by ringers will to some extent reflect the distribution of ringers and there is a
similar effect with birds which are resighted. The distribution of recoveries of dead birds
is dependent upon the number of birds in an area, the number that die and the number that
are found and reported. These data also have biases (particularly for shot birds), but as
ringers and resighters tend to be aggregated and may be in areas rarely visited by
members of the public, removing those birds recaptured or resighted reduces the bias to
some extent. For 11 of the 16 species for which we have analysable data sets, the
majority of data were from birds reported dead. The exceptions were Mute Swan
(
Cygnus olor
), Greater White-fronted Goose (
Anser albifrons
), Greylag Goose (
Anser
anser
), Black-headed Gull (
Larus ridibundus
)
and Black Tern (
Chlidonias niger
), for
which there are large numbers of resightings of individually colour-marked birds or
reading of metal ring numbers in the field. Comparisons of the distribution of birds
found dead and those found alive showed large differences, with resightings being
concentrated in western Europe (Figure 2.5). To reduce bias, but maintain maximum.

data, only reports of dead birds were plotted. Dead birds were defined as those with
EURING finding condition of 1-6 and 9 (see
www.euring.org for a full list of finding
conditions). For ducks and geese, these will mostly refer to shot birds and aggregations
will inevitably remain in the data presented. However, when using dot maps such
aggregations will tend to be masked, as multiple recoveries in the same place are not
apparent. However, it has been shown for wildfowl that the distribution of recoveries
‘deliberately taken by man’ (largely shot), is more widespread and representative than
those with other causes (Wernham
et al.
2002).
For each species a map is provided in an Annex 2.1 showing the number of birds ringed
in each country and later found dead (either within or outside that country) to put the
recovery locations into context.
2.7.1.2 Compilation of migration synopsis tables
The data generated by national ringing schemes have been analysed in some detail for
some countries (Table 2.12) and these sources have been used to generate a summary of
the known movements. To maximise the ability to refer back to individual sources,
countries or regions may appear more than once. If this occurs it is due to different
sources being used. In many species it is often the case that the species occurs in both
summer and winter and hence appear in the ‘Population’ and ‘Wintering area’ columns
but it should be noted that these are not necessarily the same individuals and the breeding
population may move and be replaced by immigrants from elsewhere in winter.

2.7.1.3 Compilation of summary maps of ring recoveries
The summary maps have been compiled from two data sources (see example of Common
Teal
Anas crecca
in Figure 2.6 below). The distribution maps are based on those
published in Bauer
et al.
(2005) and orange arrows have been overlaid to show the main
"migration streams" as revealed from the synopsis tables and the recoveries stored in the
EURING data bank. The distribution maps have not been altered for this project. This
means that in a few cases the distribution does not entirely fit with the information given
by the arrows, which represent a later state of knowledge.
Figure 2.6 Key to the distribution and movement summary maps
As always, when information from ringing and recovery points is transformed into linear
data, some personal estimation has to be included. We did this according to best
knowledge but there are some parts in the figures that clearly need to be based on more
data, a more in-depth study and probably a discussion of alternative interpretations. The
arrows mainly include information about the direction of main migration streams. They
are not intended to represent "migration pathways", since most of the species migrate on
a broad front. Their ends do not necessarily mean that migrants are expected to land
exactly at these places. Also, there is no information about length of non-stop flights in
the lengths of the arrows. A main migration event can happen along one arrow or along
several arrows in a chain. However, when there was suitable information we tried to
indicate important sites by disruption of arrow chains. Finally, the usage of very
heterogeneous sources leads to a high variance in data availability for different (sub-)

populations. This may lead to the fact that some less frequented directions may be known
and indicated for some countries (e.g. Britain, Denmark) and may be missing for others
(especially in eastern Europe).
2.7.1.4 Migration terminology
Migration can take many different forms. The seventeen species in this chapter are
generally
broad front migrants,
which migrate in short hops, stopping frequently on
route, and often have geographically diffuse migration routes. This distinguishes them
from
leap migrants
, which migrate in long-haul journeys stopping at only a few, usually
discrete, sites, such as wetlands, often in large numbers. A primary example of the latter
would be migrating estuarine shorebirds but undoubtedly some of the species considered
here, such as those that over-winter in sub-Saharan Africa, will undergo leap migrations.
The autumn and spring migration may take place across a similar network of sites but
often individuals can take different migration routes in spring and autumn. This is termed
loop migration
.
Another form of migration frequently referred to in this report is
moult migration.
Ducks,
geese and swans often become flightless when they are replacing wing feathers and
therefore need a safe moulting area (usually close to or surrounded by a large body of
water) and a plentiful supply of food. Many ducks and geese undertake moult migrations,
some of which can be long-distance. For example, there are a number of recoveries of
male Tufted Ducks moulting in Britain in early summer (June-July) in eastern Russia and
Kazakhstan during the breeding season. This also highlights that males and females may
take different routes or have different migration strategies.

2.8 Mute Swan (Cygnus olor)
2.8.1 Numbers and distribution
Figure 2.7 shows that the most important sites for Mute Swan are on the Caspian shores
of Azerbaijan, Russia, and Kazakhstan. The northern Black Sea coast of Ukraine and the
western Baltic coasts of Denmark and Germany are other notable areas of importance.
The species is only partially migratory and these areas are important all year round.
Moulting concentrations of Mute Swans in the north Caspian Sea produce by far the
highest site totals, with 344,000 having been recorded in the Volga Delta in 1987
(Kuznetzov
et al.
1998) and 121,000 on the north Caspian coast of Kazakhstan in 2003
(Table 2.13). In January, high site totals are recorded further south in the Caspian, for
example 12,593 at Gyzylagach Nature Reserve (Azerbaijan) in the 1990s and 5,450 at
Lake Sarykamysh (Turkmenistan) in 2003. The country with the largest number of sites
important for Mute Swans is Germany, where a cluster of important sites on the south
Baltic coast extends into Denmark, where the most important site in this Baltic complex
is Lolland Northwest, which held 14,565 Mute Swans in January 1994. The third most
important complex of sites important for Mute Swans is along the north Black Sea coast
in Ukraine, where 14,510 Mute Swans were counted in the Eastern Sivash in January
2000. In southeast Europe, the Meric Delta in Turkey held 8,500 Mute Swans in January
1991.

2.8.2 Mute Swan movements
The breeding area of the Mute Swan covers
west and central Europe (including southern
Scandinavia and the area around the Baltic).
The species also breeds locally in eastern and
south-eastern Europe and locally eastward to
China. The Mute Swan has also been
introduced to several other continents during
recent time. It is sedentary in some areas while
partially or wholly migratory in others.
The recovery rate of ringed Mute Swans is
very high and a large number of recoveries is
therefore available. The largest numbers of
recoveries are from Britain, Germany, the
Netherlands and Sweden. The geographical
distribution of recoveries follows to a great
extent the breeding range in Europe. Birds
from the northernmost breeding area in Sweden, Finland and the Baltic States
regularly move SW to wintering areas in southern Sweden, Denmark and northern
Germany. Mute Swans in Britain & Ireland, NW France, Belgium, the Netherlands,
W Germany and Norway are mainly sedentary but can perform short-distance
movements. Some central European breeders move west and south. Birds breeding in
Ukraine leave inland lakes and move to the coast of Black Sea, Danube Delta or
continue to the Balkans and Italy. Mute Swans in the Caspian Sea area mainly
perform short-distance movements within this area. It is well known that the species
can perform mass movements in severe winters in order to leave freezing lakes. The
distribution by months indicates that many Mute Swans leave inland areas in the north
and east, and concentrate in coastal areas during the winter months. Non-breeders
perform moult migrations and are sometimes found in large concentrations in
restricted areas.

2.9 Greater White-fronted Goose (Anser albifrons)
2.9.1 Numbers and distribution
The biggest wintering concentrations of White-fronted Geese occur in lowlands north and
west of the Black Sea in Ukraine, Romania and Bulgaria, in central Europe on the plains
of Hungary, and in northwest Europe in the Netherlands and north Germany (Figure
2.10). All these populations migrate to northern Russia to breed, and a number of key
staging areas are known in Russia and Kazakhstan.
The most important sites for Greater White-fronted Goose are in The Netherlands and
Germany where 112,000 at Ijsselmeer in 1991 and 40,130 at Düffel in 2002 are typical of
the highest peak counts. (Table 2.15). The north and east coastal regions of the Black Sea
also hold large flocks, with 193,873 at Shabla Lake in Bulgaria in 2000 being the highest
single recent count. The lowlands adjacent to the Black Sea in Romania and Ukraine have
recorded peak counts of 78,000 at Lake Sinoie in 1992 and 85,042 in the Central Sivash
in 1998, respectively. The most important wintering site for the central European
wintering birds is Hortobagy in Hungary, where there were 130,000 in January 1992. The
species stages in spectacular numbers at a number of sites in Russia and Kazakhstan,
including Veselovskoye Reservoir (240,000 birds, Gineev et al., 2002), The Neman River
Delta (90,000, Svazas et al., 2003), and Olonets Plain, Karelia (80,000, Berezovikov,
2002). In Kazakhstan, 423,000 were recorded staging at lakes north of Kurgalin N R, and
many high counts are made in the autumn in the Kustanay region.

2.9.2 Greater White-fronted Goose movements
This species breeds at high latitudes in
northern Europe, Asia and North
America. It is a long-distance migrant
with wintering areas in Europe, south
and east Asia and southern North
America.
The only country in Europe where the
White-fronted Goose has been ringed in
large numbers is The Netherlands. A
reasonable number of recoveries is also
available from Britain & Ireland.
Recoveries from the winter period
(December February) are mainly
reported from western Europe, including
Denmark and Germany, and smaller
numbers also in central and southeastern
Europe as well as in Turkey. The return
migration of the White-fronted Goose
starts in March with recoveries being spread eastwards in Europe. In April a large
number of recoveries is reported from Belarus and western Russia continuing north in
May. In June the birds are found in the breeding area close to the Arctic coast. A
small number of recoveries is found in May close to the border of Kazakhstan and
they are probably from birds heading for breeding sites on Taymyr Peninsula, where
some recoveries are found during the breeding season. Birds of the Greenland
breeding form, A. a. flavirostris start to appear on Iceland in April and in May
recoveries are reported from southeastern Greenland.
Autumn migration from northern Russia starts in August and continues until October.
The route followed is more to the north then during spring and birds pass through the
Baltic. In September and October recoveries are found in northern Kazakhstan and
this probably involves birds from breeding areas on Taymyr on their way to wintering
sites in southeastern Europe and Turkey. Birds breeding in Greenland are found on
stopover in Iceland until November and they winter mainly in Scotland & Ireland.
North Siberian breeders are also found in the Caspian Sea area and in Iraq, while birds
from breeding sites further east winter in south and East Asia.

2.10 Greylag Goose (Anser anser)
2.10.1 Numbers and distribution
Greylag Goose has a complex population structure in Europe and many countries have
non-migratory populations which are joined by migrants on passage and in winter.
Denmark, The Netherlands, Spain, the UK, Germany and Hungary hold large wintering
populations. This is a numerous species in Central Asia and Iran, with important
breeding and staging sites in Kazakhstan, and wintering sites in Uzbekistan,
Turkmenistan and especially Iran.
The highest counts of Greylag Geese have been made at sites in Russia and Kazakhstan
(Table 2.9). 100,000 have been recorded staging at the Stepnoi State Refuge, and 50,000
at the Svir Delta in Russia, and 70,000 were counted at Sholack Lake, Kazakhstan in
January 1995. Large numbers winter in Spain, where 43,521 at The Doñana National
Park 1n 1995 and 39,296 at Lagunas de Vilafafila in 1999 are high recent count totals.
Iran has more records of important concentrations of Greylag Geese than other countries
with 48,100 at Fereydoon Kenar in 2003 by far the highest count, followed by 12,700 at
Varamin Lake in 1997. In Northern Europe, 57,104 at Westerschelde and Saeftinge, The
Netherlands in 1999, 22,710 at Filso Lake, Denmark in 1996 and 19,150 at Loch of
Skene, Scotland in 1991 are typical high counts. In central and eastern Europe, 22,000
were counted at Fulupszallas Szikes To, Hungary, in 1995, and 21,822 at the Danube
Delta, Romania in 1992. There are important winter concentrations in North Africa,
where Lac Fetzara, Algeria, held 13,400 in January 1994.

2.10.2 Greylag Goose movements
The Greylag Goose breeds locally in a large
area of Europe, except for the southwestern
part, and across central Asia. Two subspecies
are present in Europe, the nominate form in
the west and A. a. rubrirostris in southeastern
Europe. Six populations are recognized within
Europe and feral populations are also found in
several areas. Populations in the north and east
are wholly migratory, while some populations
further south are resident.
Largest numbers of recoveries are from
Greylag Geese ringed in Denmark, Britain and
Sweden. The recoveries reported during
winter are found in western and southern
Europe, in northern Africa and a few in the
area of the Black and Caspian Seas. Return
migration starts early, already in January, and
continues until April. During the breeding
season, recoveries are spread out, including Iceland, coast of Norway, southern
Sweden, Ukraine, southern Russia and Kazakhstan. Autumn migration commences
late and recoveries start to appear in southwestern Europe in October. In November,
the Greylag Goose has left Iceland, the numbers found in North Africa increase and
recoveries in the east are found close to the northern part of the Black Sea and west of
marismas of the Caspian Sea. The southwest flyway is narrow and follows the
Atlantic coast in France, cross the Iberian Peninsula to marismas of the Guadalquivir
in southern Spain. Birds breeding in Britain are resident, while birds from Iceland
winter mainly in Scotland. Breeding birds from Norway, Sweden, Denmark and
western Germany migrate SW to Spain, but an increasing number have remained
during winter in the Netherlands and France since the mid 1980s. Many Greylag
Geese from eastern Sweden, Finland and east central Europe migrate south and winter
in Italy, the Balkans and in North Africa (Algeria and Tunisia). Birds from the Black
Sea region and Turkey show limited movements to coastal areas. Breeding birds from
areas north of the Caspian Sea and in western Siberia move south to areas including
Pakistan and India. Moult migration in non-breeders involves movements from central
Europe to the Baltic, Denmark and the Netherlands.

2.11 Red-breasted Goose (Branta ruficollis)
2.11.1 Numbers and distribution
Red-breasted Goose has a geographically restricted range. It breeds on the Taymyr
Peninsula and winters on the Black Sea lowlands of Bulgaria, Romania and Ukraine
(Figure 2.16). The range extends into the European Union in eastern Greece. Important
staging areas have been identified in Kazakhstan.
The most important recorded sites for wintering Red-breasted Goose are in Bulgaria,
where 55,845 were counted at the Shabla Lake complex in January 1993, 17,733 at
Durankulak Lake in January 2000 and 16,860 at Mandra Lake in January 1997 (Table
2.19). In Ukraine, 13,500 were recorded in the Central Sivash in 2000 and 12,000 at
Dnievstrovsky Liman in 2001. In Romania, highest recorded counts are 10,000 at
Techirgiol in 1999 and 8,000 in the Danube Delta in 1993. The Kustanay Region of
Kazakhstan is a crucial autumn staging area, where the highest single count was 19,600 at
Kulykol Lake in 1999. The key site in the European Union is the Evros Delta, Greece,
where 750 were counted in 1997.

2.11.2 Red-breasted Goose movements
This species breeds in a limited area of
northern Russia, mainly on the Taymyr,
Gydan and Yamal peninsulas. It has a very
restricted wintering range and has because of
this been classified on the IUCN Red List as
Vulnerable.
The Red-breasted Goose has been ringed in
very low numbers within Europe. Only four
recoveries are available and one of these,
ringed in the Netherlands, has been reported
as shot on Yamal. The species changed its
wintering range from about the 1960s from
Azerbaijan westwards to the Black Sea coast
in Romania and Bulgaria. Small numbers of
birds also winter in Ukraine and northern
Greece, in the latter area often in connection
with hard weather. During recent years, a few
birds are reported from Comaccio/Venice area
in northern Italy almost annually. It is believed that the majority of the population
nowadays winter in the Black Sea area. The autumn migration follows narrow routes
southwest through Russia along rivers to the area north of the Caspian Sea and then
westward to the Black Sea. Several staging areas are used during spring migration in
Ukraine, Russia and Kazakhstan. Stragglers are regularly found in western Europe
and the number observed seems to have increased after the shift in wintering areas.

2.12 Eurasian Wigeon (Anas penelope)
2.12.1 Numbers and distribution
Eurasian Wigeon winters in high numbers in The Netherlands, which forms the core
of the most important belt of winter distribution which includes Denmark, Germany,
Belgium, The UK and Ireland (Figure 2.19). Important numbers winter in France and
there are key concentrations around the Mediterranean in Morocco, Spain, Algeria,
Tunisia, Italy, Albania, Greece, Turkey and Egypt. Some of the biggest
concentrations occur in Iran, on the Caspian shore and in the southwest. Important
staging areas have been identified in Russia and the Baltic states.
A crucial staging area in Russia which includes Lake Ladoga and the eastern Gulf of
Finland is detailed in Buzun (2005), who estimates that 500,000 Eurasian Wigeon
pass through on migration (Table 2.20). In west Asia, 109,895 were counted at
Gyzylagach Bay, Azerbaijan in January 1996. The most important sites in Iran are
Fereydoon Kenar and Bakhtegan Lake, where 31,200 were counted in January 1993
and 28,515 in January 1997, respectively. The most important concentration of
important sites is in the Low Countries where over 5,000 have been counted at more
than 50 sites in The Netherlands, and 9 sites in Belgium. The most important of these
is Markermeer, where 86,804 were counted in January 2002. Adjacent parts of
Germany also hold high numbers, and four sections of the German Wadden Sea have
recorded between 15,000 and 30,000 Eurasian Wigeon since 1990. In the UK, 29 sites
have recorded more than 5,000 birds since 1990, the most important being the Ribble
Estuary, with 69,149 counted in January 1999. In the Mediterranean region, the
highest counts have been made at the Po Delta, Italy, with 62,963 in January 2002,
and Lac Ichkeul, Tunisia, where 53,380 were counted in 1997. Greece, Albania and
Turkey hold important numbers, with 35,046 at Amvrakikos Wetlands in 1995,
27,198 at Karavasta Complex in 2000, and 27,190 at Yumurtalik Lagoons in 1999. In
the West Mediterranean region, Spain holds a number of key concentrations, the
highest recent count having been at being Lucio del Membrillo, where 35,000 were
counted in 1992. Merja Zerga, Morocco recorded 25,980 in January 1994, and Lac
Oubeira, Algeria, 24,420 in the same year.

2.12.2 Eurasian Wigeon movements
This species has a large breeding area
covering northern latitudes in the Palearctic,
from Iceland in the west to the Bering Strait
in the east. With the exception of some
small populations in western Europe, most
populations are highly migratory with
wintering areas from Europe in the west to
southern Asia and Japan in the east. Only
small numbers are found south of the Sahara
desert during winter, mostly in the East
African Rift Valley.
The majority of the recovered Eurasian
Wigeon have been ringed in western Europe
(Britain and The Netherlands), which is one
out of the five main wintering areas for the
Eurasian Wigeon. Large numbers are found
in west Europe during the winter months
(December-March), but recoveries are also reported in south Europe and eastwards to
the Black Sea and the Caspian Sea. The most intense phases of
return migration
through southern Russia occur in April. During the breeding season (May June)
Eurasian Wigeon recoveries are reported from west Europe, Iceland, Scandinavia and
Russia. Concentrations of recoveries during the breeding season are found east of the
Urals along the river Ob and only a few recoveries are reported east of 90°E. Autumn
migration continues until October and seems to follow a more northerly route than
during spring migration. The return migration route seems to be more direct across
central Europe. Recoveries in southern Russia and in Kazakhstan in autumn might be
a result of moult migration of males and non-breeders. Birds breeding in Siberia are
known to winter at the Caspian Sea and the Black Sea coasts, as well as in the
Mediterranean area. Birds wintering in west Europe continue further south during
severe winters.

Eurasian Wigeon Anas penelope
Distribution: Europe and Asia, between 50°N and 70°N; small numbers West and East Africa and Arabian Peninsula. Five main wintering groups: NW-Europe
(1,250,000), Black Sea and Mediterranean Basin (560,000), between. SW-Asia and NE Africa (250,000), South Asia (250,000), Eastern Asia (100,000-1,000,000)
Moult migration: Males (late May-July) and non breeders moult in southern west Siberia, Russia, Volga Delta, Urals, upper Pechora, Estonia, S-Sweden, Denmark
and Iceland; females (late June - early September)

2.13 Gadwall (Anas strepera)
2.13.1 Numbers and distribution
Figure 2.22 shows that the biggest Palearctic concentrations of Gadwall are in Iran
and there are major moulting sites across the Caucasus in Russia. Other large
concentrations are in southern France and northern Tunisia and Algeria. This is not a
numerous species and other centres of population are in southern England, The
Netherlands, lakes north of the Alps, Spain, Italy and Greece.
Of 40 sites where more than 3,000 Gadwall have been counted, 22 are in Iran and
three in Azerbaijan (Table 2.22). The most important of these are Gyzylagach Nature
Reserve (Azerbaijan) where 21,100 were counted, and Fereydon Kenar, Iran, where
there were 21,000 in 2003. There are few key sites in the Black Sea- East
Mediterranean region, the most important being Amvrakikos Wetlands, Greece,
where 3,600 were counted in 1998. The West Mediterranean is more important. The
highest January count of all was made at Lake Oubeira, Algeria, in 1994, when
23,920 were counted, and Lac Fetzara recorded 13,800 in 1998. The Camargue,
France, recorded 13,570 in 1994, and in Spain, 4,686 and 4,630 were counted in the
Ebro Delta and Doñana National Park in, respectively, 1999 and 1994. The Grado
Lagoon, Italy recorded 3,188 in 1992. Further north in Europe counts are mostly
lower, with 5,769 at the Bodensee (Germany-Switzerland-Austria) in 1996, and 3,042
on the river Rhine in Germany between Breisach and Nonnenweier in 1990. The
highest count recorded in The Netherlands was 2,220 at Grevelingen in 2002.

2.13.2 Gadwall movements
The Gadwall is a Holarctic species with
breeding areas in northwestern North
America, locally in Europe and eastwards to
northern China. The species is largely
migratory, but resident in western and
southern Europe.
Ringed in small numbers in most countries,
the largest numbers of recoveries are from
birds ringed in Britain, Russia, The
Netherlands and Germany. Recoveries
between December and February are
concentrated in western Europe, but some
are also reported from the Mediterranean
and the Caspian Sea areas. Few recoveries
are reported during March, while recoveries
are spread out in southern Russia and
Kazakhstan in April. During the breeding
season, recoveries are found in western and central Europe and in southern Russia
east to southwestern Siberia. The number of recoveries increases in western Europe in
September and in November most birds in Russia have moved to coastal areas of the
Caspian Sea. Birds breeding in Britain, Denmark, Scandinavia, the Baltic, Poland and
European Russia migrate to western Europe and the Mediterranean. Central European
birds and birds breeding in eastern Europe and southwestern Siberia winter in the area
of the Black and the Caspian Seas, eastern Mediterranean, Turkey and south to the
Nile and a few as far as East Africa. Birds breeding in Siberia also winter in the
Caspian Sea, in Turkmenistan, Uzbekistan, Pakistan and India. Important moulting
areas for males are known from the northern Caspian Sea area, e.g. the Volga delta,
but also in lakes in Kazakhstan.

2.14 Common Teal (Anas crecca)
2.14.1 Numbers and distribution
Common Teal is numerous and widespread in winter and in Europe is only absent
from upland areas and those affected by prolonged freezing (Figure 2.25). Highest
totals are recorded in Iran and Azerbaijan. In Europe, more Common Teal are
counted in Greece than in any other country, and other key sites are in Albania, Italy,
France, Spain and Portugal. Important numbers also occur in the UK and Ireland, and
in a belt stretching east through The Netherlands and Germany. Estimates have been
made for breeding areas in Northern Russia and key staging sites have been identified
on the north Caspian coasts of Russia and Kazakhstan.
The highest January counts are in Iran and Azerbaijan, and Common Teal has a more
dispersed distribution in Europe (Table 2.24). The highest recorded count is of
210,300 at Bakhtegan and Tashk lakes, Iran in 1995, and there were 93,000 at
Fereydoon Kenar in 2003. In Azerbaijan, similar numbers have been recorded at
Kirov Bay and Gyzylagach Nature Reserve, where 66,200 and 62,245 were counted in
1991 and 1996, respectively. The highest counts in Europe come from Greece, where
100,750 were counted at the Evros Delta, and 38,400 at Amvrakikos Wetlands in
1999, and 31,500 at Kerkini in 1995. 40,000 were counted at Skadarsko Jezero, on
the border of Montenegro and Albania, in 1993. In the West Mediterranean Region,
Spain is important, with 84,100 at The Doñana National Park in 1991 and 42,100 at
De La Algaida A Hato Villa in 1991. The Camargue (France) Venice Lagoon (Italy)
and Tejo Estuary (Portugal) are additional sites where more than 25,000 have been
counted in this region. In France, the Low Countries, The UK and Ireland there are
high densities of sites where lower counts were recorded, and the highest count in
these countries was made at the Somerset Levels (UK) where 33,350 were counted in
2003.

2.14.2 Common Teal movements
The Common Teal breeds in a large area
in the northern Palearctic, from Iceland to
the absolute eastern part. The closely
related Green-winged Teal Anas
carolinensis breeds in North America. The
Common Teal is mainly migratory, but
small populations in west Europe are
largely resident. Wintering areas are found
in Europe, North Africa and Asia.
The largest numbers of recoveries are
from birds ringed in Britain, the
Netherlands, Denmark and Russia.
Between December and March, recoveries
are reported in a large area of west and
south Europe as well as in the area of the
Black Sea and the Caspian Sea. A few
recoveries are reported also in North
Africa and in the Middle East. Small
numbers cross the Sahara desert and there are two recoveries supporting this
movement. Between January and February there is a decrease in the number of
recoveries in Northen Africa, while March shows a clear decrease in recoveries in
Iberia and a further increase in Northern Italy. The speed of return migration seems to
increase significantly during April and be directed northeast on a broad front.
Recoveries from the breeding season (May-June) are spread out in northern Europe
and Russia east to about 70°E.
The autumn migration seems to start in July and continue until October. The autumn
migration of the Common Teal is directed southwest and different flyways parallel to
each other are known to exist. The population breeding east of the Ural Mountains
and in Siberia winters in the eastern Mediterranean, the Black Sea and the Caspian
Sea area. Some birds are known to follow the river Nile south to East Africa. Siberian
birds also winter on the Indian subcontinent. In severe winters, Common Teals in west
Europe continue to the Atlantic coast and south to northwest Africa. It has been
shown from ringing recoveries that birds in different seasons can change between
flyways.

Common Teal Anas crecca
Distribution: Holarctic, across North America and northern Eurasia. Three subspecies: nominate in Northern Eurasia; A.c.carolinensis in North America; A.c. nimia in
the Aleutian Islands Western Eurasian populations winter south to North Africa and the Gulf. Main wintering areas: Northwest Europe, Black Sea/Mediterranean,
Southwest Asia. Wintering sites may change from one year to another.
Moult: discrete moult migration in West and Central Europe (Denmark, Netherlands, SE-Germany), Teal breeding in SW-Siberia complete wing moult at lakes in SW-

2.15 Mallard (Anas platyrhynchos)
2.15.1 Numbers and Distribution
Mallard is the most numerous and widespread duck species in Europe and is only
absent in January from upland areas and those affected by prolonged freezing (Figure
2.29). It has a similar winter distribution to Common Teal but is more abundant and
more tolerant of freezing conditions, occurring in high numbers further east and north
than any other freshwater duck species. High densities of important sites are found in
a large area encompassing Belgium, The Netherlands, northern Germany and
Denmark and a smaller area centred on Hungary and Croatia. There are also large
numbers of key sites on the northern and western coasts of the Black and Aegean Seas
in Russia, Ukraine, Romania, Bulgaria and Greece. Spain, France, Switzerland, Italy
and Albania also host important key sites. Some of the highest counts of all have been
made in Uzbekistan, Turkmenistan, Azerbaijan and Iran, especially along the shores
of the southern half of the Caspian Sea and in lakes of southern Iran.
The highest counts have been made in Iran, Uzbekistan, Azerbaijan, and
Turkmenistan, and in Europe the highest site totals are recorded in Eastern, Southern
and Central European countries, with rather few Key Sites in the West and North
(Table 2.26). At Bakhtegan and Tashk Lakes, Iran, over 300,000 were counted in
1995. Kuyumasar, Uzbekistan recorded 134,000 in 2004, and Gyzylagach Nature
Reserve, Azerbaijan, 93,000. In the Black Sea-East Mediterranean region, 62,210
were counted at Shabla Lake (Bulgaria) in 1997, 52,350 at The Evros Delta (Greece)
in 2000, and 50,000 at Kopacki Rit (Croatia) in 1998, as well as 49,818 in the Central
Sivash (Ukraine) in 1998. Other important sites in this region are Eastern Sivash
(Ukraine) where 40,000 were counted in 1991, and the Black Sea Biosphere Reserve
where there were 38,300 in 1990. Further west in the Mediterranean region, the peak
count at Venice Lagoon, Italy, was 46,156 in 2002, and in the Camargue, France,
41,143 also in 2002. The Ebro Delta, Spain recorded 43,160 in 1997. Further north
and west, 41,916 were counted at Dümmer, Germany in 1998, and 37,850 were
counted at Cours du Rhin (France) in 1990. The highest count in Hungary was 30,000
at Geszt. Begecsi Halastavak in 2002, and 25,000 were recorded at three further sites.

2.15.2 Mallard movements
The breeding area of the Mallard covers a
large part of the Holarctic, across North
America and Eurasia between 35°N and
70°N. Birds breeding in temperate areas
are mainly sedentary while birds breeding
in northern areas, where open waters are
hard to find during winter, are migratory.
The Mallard winters in a large part of
Europe and across central Asia.
Extensive ringing of Mallards has been
carried out in many countries and the
largest numbers of recoveries are from
birds ringed in Britain, Denmark, the
Netherlands, Sweden and Russia.
Recoveries between December and
February are strongly concentrated in west
Europe, from southern Sweden southwards, but many recoveries are also reported in
south Europe and in the area of the Black and the Caspian Sea. Between January and
February there is a decrease in recoveries in Mediterranean countries like Italy and
SW France; this pattern gets stronger and involves also Iberia between February and
March. The most intense phases of return migration seem to take place in March and
continue into May in the most northern areas. During the breeding season, Mallards
are found in most of Europe, including the northernmost areas, and eastward to about
70°E. The autumn migration seems to start in August and continue until November.
Various flyways have been demonstrated and birds breeding in northwest Russia,
Finland, Sweden and the Baltic states migrate to wintering areas in west Europe and
Britain & Ireland. Birds breeding in west and southwest Europe are mostly sedentary
or perform only short-distance movements. Birds from central and eastern Europe
move south or southeast to the Mediterranean or to the Black Sea. Mallards breeding
in central Russia, western Siberia and Kazakhstan move WSW-SSW to east
Mediterranean, the Black Sea and the Caspian Sea, but also to areas east of the
Caspian Sea and south to Iran-Afghanistan. Large numbers of males from breeding
areas in Ukraine to west Siberia are known to gather in the Volga delta, Caspian Sea,
during moult. Severe winters result in Mallards moving further south or southwest.

2.16 Northern Pintail (Anas acuta)
2.16.1 Numbers and distribution
Northern Pintail is a significant migrant to Subsaharan Africa and Iran, and in Europe it is
primarily a coastal species in winter (Figure 2.32). The most important wintering sites are in
the Sahel zone of west Africa in Senegal, Mali, Niger, Nigeria and Chad. There are crucial
wintering sites on the Caspian coast in Azerbaijan and Iran, and in lakes of southern Iran. In
Europe, the most important countries in January are Greece, Spain, The Netherlands, France
and UK, and Italy and Portugal are also important.
Between 100,000 and 150,000 have been counted at five sites, three of them in West Africa,
and two in Iran (Table 2.28). These sites are two parts of The Inner Niger Delta in Mali, and
the Djoudj National Park in Senegal, and in Iran, Ezbaran Damgah, and Bakhtegan and
Tashk Lakes. Relatively few winter in Central Asia. Other key sites in West Africa include
Lac Fitri, Tchad, where 36,865 were counted in 1999, Hadejia-Nguru, Nigeria, where there
were 34,866 in 1998, and Diawling, Mauritania, where 33,100 were counted in 1995. The
most important sites in Europe are in Greece, where 35,965 were couinted in the Evros Delta
in 1999, and 12,477 at the Amvrakikos Wetlands in the same year. Spain is the only other
European country where five-figure site totals have been recorded in January, with 28,790 at
Caño Del Guadiamar in 1997, and 17,500 at Embalse de Gargáligas in 2003. Between 8,000
and 10,000 have been recorded in Italy at Venice Lagoon, in France at Baie De L’Aiguillon
Et Pointe D’Arcy, in Spain at Marisma de Hinojos and Lucios de VetaLengua Y Aguias
Rubia, and in The Netherlands at Westerschelde.

2.16.2 Northern Pintail movements
The breeding area of the Pintail covers a
large area of the northern Holarctic,
across North America and Eurasia. The
Pintail is mainly migratory and in most
regions is a long-distance migrant.
Wintering areas are spread out in
western and southern Europe, across
Africa south of the Sahara, southwest
Asia, India, southern China and Japan.
North American Pintails move south and
leave most of the breeding range during
winter.
Large numbers of recoveries are
available only from birds ringed in
Russia, Britain and the Netherlands.
Recoveries from the period December
February are found in western and
southern Europe, North Africa and in the area of the Black and Caspian Sea. A few
recoveries are also reported from southwest Asia and India as well as from areas south
of the Sahara in Africa. An increase in recoveries in Mediterranean countries like Italy
is observed between January and February, becoming more intense between February
and March. The most intense phases of return migration start in March, become
prominent in southern Russia in April and reach the northernmost areas in May.
Recoveries from the breeding season (May-June) cover a large area to about 80
o
E,
with concentrations of recoveries in southwestern Siberia and northern Kazakhstan.
The autumn migration seems to start in August, but recoveries are spread out in
Ukraine, western and southern Russia and in Kazakhstan as late as October. Birds
breeding in Iceland, Sweden, Finland, the Baltic States and northwest Russia migrate
SW-S mainly to west and south Europe and often along the Atlantic coast. Birds from
western and central Siberia move to the Mediterranean, the Balkans and the area of
the Black and Caspian Sea as well as to India. Some also move to western and
southwestern Europe, and further to tropical West Africa. Birds from Siberia and
northern Russia also winter in southwest Asia, the Nile Delta and in wetlands in
Sudan and Ethiopia. Recoveries of ringed birds indicate that interchange between
flyways in different years exists. Moult migration is common in Pintails and large
numbers of males are known to gather in southwestern Siberia and northern
Kazakhstan, where large concentrations of recoveries are found.

2.17 Garganey (Anas querquedula)
2.17.1 Numbers and distribution
Garganey is the most migratory of all Palearctic duck species and Russian and
European breeding populations migrate almost entirely to sub-Saharan Africa and
tropical Asia. There are numerous key wintering sites throughout the West African
Sahel zone stretching from Senegal and Mauritania, through Mali, Burkina Faso,
Niger, Nigeria, Chad and the northern tip of Cameroon (Figure 2.35). Smaller
numbers spend the northern winter in East Africa from Sudan south to Kenya.. A
number of important breeding areas have been identified in Russia, and spectacular
numbers occur on migration on the Caspian coasts of Russia and Kazakhstan, and
also, at least until the 1970s, in Egypt (Cramp & Simmons 1977). Much smaller
numbers winter as far north as Azerbaijan.
The most important wintering sites for Garganey are the Djoudj National Park in
Senegal, where 288,053 were counted in January 2000, and the Inner Niger Delta,
Mali, where 206,000 were recorded in 1994, and where numerous five-figure counts
of various quadrats have been made (Table 2.30). Lake Tchad in Tchad-Nigeria-
Cameroon is a crucial site, but consolidated totals are not available and a count of
68,760 at Quadrat 93 in Cameroon is the highest count on record. In Mauritania,
57,272 were counted at Mahmouda in 2004, 50,350 at Lac d’Aleg in 1996 and 25, 475
at Bassin De R’Kiz in 2000. In Senegal, 31,500 were counted at Les Trois Marigots
in 1998. In East Africa, the most important wintering sites are in Sudan, where 10,000
were counted at Bagga Sites in 2003, and 8,750 at Taror Ibrahim in 1997.

2.17.2 Garganey movements
This species breeds in Palearctic, from
west Europe to eastern Asia mainly
between 42
o
N and 65
o
N. It is highly
migratory with main wintering areas
across tropical Africa south of the Sahara,
in India and in southern Asia. In Africa, it
winters along a line of approximately 10-
15°N from Senegal to Chad, with smaller
numbers found in eastern Africa.
Particular concentrations are found in the
Senegal and Niger deltas.
Apart from a few sites in Russia,
Garganey are localised and sparsely
distributed in the breeding season and
have been ringed only in small numbers in
most countries in Europe. The largest
numbers of recoveries are from ringing
carried out in Russia and the Netherlands. Most of the recoveries during winter have
been reported in southern Europe, in Italy and in the Balkan region. A smaller number
of recoveries has also been reported from south of the Sahara, mainly in Senegal and
Mali. The number of Garganey wintering in Europe is small and it is likely that the
chance of receiving recoveries from those that stay in Europe is much higher than
from those that migrate to south of the Sahara, hence the apparent mismatch in the
number of recoveries versus numbers of wintering birds. Mediterranean crossing is
evident from the increase in recoveries in Italy between January and February; this
country, together with the Balkans and Greece, is involved in strong return
movements in March and, to a lesser extent, in April, when no more recoveries are
reported from the African winter quarters. The return migration continues into
southern Russia and Kazakhstan in April and further north in May. Recoveries from
the breeding season are spread out from west Europe to Siberia at about 90°E.
Autumn migration starts in August and some Garganey are still reported in Russia in
October. Birds breeding in western and northern Europe use two main routes; they
either pass the Iberian Peninsula or the central Mediterranean on their way to West
Africa via Morocco or Algeria. Eastern European birds pass through the eastern
Mediterranean to East Africa. Siberian birds also pass eastern Mediterranean and
southwest Asia on their way to East Africa, reaching as far west as Chad, but some
move also through eastern Iran to Pakistan, India and Sri Lanka. Return migration
from both West and East Africa is concentrated in the central Mediterranean. This
apparent loop migration is supported by the large number of recoveries reported in
Italy between February and April.

Distribution: Palaearctic, across Europe and Asia, mostly between 42°N and 65°N. No biogeographical populations defined in Western Eurasia. Two main migration
routes: one from Central Europe through the Mediterranean and one via Spain along Atlantic coast. In winter, two groups, one wintering in East Africa (through SW-
Asia), and one in West Africa. Pair formation takes place in winter and males often follow females to her breeding grounds

2.18 Northern Shoveler (Anas clypeata)
2.18.1 Numbers and distribution
The most important January concentrations of key sites for Northern Shoveler are in
the Mediterranean and south Caspian regions and Iran, and the species is a significant
trans-Saharan migrant. (Figure 2.38). In the Mediterranean region, Spain is the most
important country for this species, and there are also large numbers of key sites in,
Portugal, Morocco, Algeria and Tunisia, and in the East Mediterranean, in Albania,
Greece, Egypt, Israel and Jordan. In the Caspian region, Azerbaijan and Iran are the
most important countries. Birds spending the northern winter in Subsaharan Africa
concentrate in East Africa in Sudan, Ethiopia and Kenya, and in the west African
Sahel zone in Senegal, Mauritania, Niger, Nigeria and Chad.
The highest January count of Northern Shoveler, 41,000 birds, was made at
Gyzylagach Nature Reserve, Azerbaijan (Table 2.32). Six sites in Spain recorded
January counts between 28,752 and 36,855: Embalse de Sierra Brava in 2003,
Doñana National Park in 1991, Lucio de los Ansares in 1992, Lucios De Beta La
Palma-Isla Mayor (2003), Marisma de Hinojos (2001) and Parque Natural De La
Albufera (1991). More than 10,000 birds were counted at six further sites in Spain.
In France, two sites have recorded five-figure peak counts, The Camargue in 2004
with 19,176, and Lac de Grandlieu in 2001 with 12,950. In the East Mediterranean
region, 27,070 were counted at the Amvrakikos Wetlands (Greece) in 1996, and
17,410 at the Karavasta Complex, Albania in 2000. In Egypt, counts of 15,427 at
Lake Burullus and 12,097 at Lake Manzala were peak counts in 1990. Elsewhere in
North Africa, 10,960 at Merza Zerga (Morocco) in 1991 and 10,000 at Sebkha Kelbia
(Tunisia) in 1995 are the highest peak counts. In Iran, Bakhtegan Lake recorded a
count of 25,689 in 1997 and Gomishan Marsh 23,155 in 2003. In Subsaharan Africa,
the highest peak count of 22,260 was made at Lake Abijatta, Ethiopia in January
1994. A count of 19,800 was made at the Djoudj National Park, Senegal in 1998, and
17,095 at Diawling, Mauritania in 2004.

2.18.2 Northern Shoveler movements
Shoveler breed across a wide geographic
region that includes both northwestern
North America and a large area in northern
Eurasia south to about 40
o
N in some areas.
Wintering areas spread out in western and
southern Europe, southern Asia eastwards
to Japan. The Shoveler is regularly found
during winter in areas south of the Sahara
along a line of approximately 12°N, from
Senegal in the west to Sudan in the east
and then south along the rift valley to
Kenya.
In Europe, the largest concentrations tend
to occur in the southern countries of Spain
and France and eastwards into Turkey and
Greece. Further concentrations occur around the Caspian Sea and in southern Iran.
The largest numbers of recoveries are from birds ringed in Russia, the Netherlands
and Britain. Recoveries between December and February are mainly found in western
and south-western Europe and in northwest Africa. Single recoveries are also reported
eastwards to the area of Caspian Sea. Several recoveries are also found in Senegal in
West Africa. A tendency to decrease in the number of recoveries from Iberia and Italy
is recorded between January and February, while the intensity of return movements
increases in March, with a further decrease in Iberia and strong influxes of migrants in
Italy. In April, recoveries are spread out in southern Russia and Kazakhstan, while
birds are reported from areas further north in May. Concentrations of recoveries in
coastal areas in western Europe in July tend to be moulting males. The autumn
migration starts early and many birds start moving west in August and concentrations
are found along the Atlantic coast between September and November. A small
number of recoveries in Italy during autumn supports the idea that the species
performs a loop migration.
Shovelers breeding in northern Europe and northwestern Russia move SW to western
and southwestern Europe, North Africa as well as to tropical West Africa. Birds from
Britain & Ireland move south to France and Spain, while birds from breeding areas in
central and eastern Europe move to western Europe and the Mediterranean basin.
From Russia, Siberia and Kazakhstan birds move either to Mediterranean, southwest
Asia and East Africa or to the Caspian area and further south to Pakistan and India.
Males perform moult migration during summer and gather in some localities in
Europe and Russia, e.g. IJsselmeer, Matsalu Bay and Volga delta. Typical for many
duck species is that pair formation takes place in winter and males often follow
females to the breeding site.

2.19 Red-crested Pochard (Netta rufina)
2.19.1 Numbers and distribution
Numbers of Red-crested Pochard are highest in the Caspian region and Central Asia.
Further west there are relatively small numbers distributed in Iberia and soutern
France, in lakes north of The Alps, and from the Balkans to Turkey and the northern
Black Sea (Figure 2.41). Important breeding and staging sites have been identified in
the northern Caspian region of Russia and Kazakhstan, and the most important
wintering concentrations have been counted in Azerbaijan, Iran, Turkmenistan,
Uzbekistan and Kyrgyzstan. In Europe, the Swiss Lakes, and the Bodensee, which
extends into Germany and Austria, hold the highest numbers, and a shift in population
to this region in the 1990s from Spain and France has been well documented (Keller
2005). In southeast Europe, The Sivash, Ukraine and Lake Ohrid on the borders of
Greece, Albania and Macedonia are the most important sites, and a number of the
Turkish lakes also hold important concentrations.
Table 2.34 shows that two outstandingly important sites for Red-Crested Pochard in
January are Gyzylagach nature Reserve, Azerbaijan, where a peak count of 188,000
has been recorded, and the Volga Delta, Russia, where the peak count was 120,000.
The highest concentration of key sites for this species is in Turkmenistan, where
counts exceeding 4,000, and up to 67,900, have been made at 18 sites. Four sites in
Uzbekistan and four in Azerbaijan also reached these levels, and at Issyk Kul in
Kyrgyzstan, 30,677 were counted in 1999. In Europe, the highest counts in recent
years have been at The Bodensee in Switzerland-Germany-Austria, where 12,204
were counted in 1999. Other lakes in Switzerland are increasingly important, and
11,766 were counted at Vierwaldstattersee in 2000, 9,730 at Lake Neuchâtel in 2001
and 4,067 at Lac Léman in 2002. Further east in Europe, 7,000 were counted at Lake
Ohrid in Macedonia-Albania-Greece in 1990, and 10,000 in the eastern Sivash in
2000. The most important sites in the West Mediterranean in January are the Ebro
delta, Spain, where 8,375 were counted in 1999, and Parque Natural De La Albufera
where there were 8,360 in 1991. The Camargue, France, is also important, and 4,000
were counted there in 1991.

2.19.2 Red-crested Pochard movements
This is a Palearctic species breeding
locally across southern and central Europe
to west and central Asia. The Red-crested
Pochard is migratory or partially
migratory, except for a small feral
population in the UK, which is largely
sedentary. In western Europe wintering
concentrations occur in southern Germany
and Switzerland and locally in Spain. The
major wintering concentrations occur
around the Caspian Sea and eastwards into
Turkmenistan.
The Red-crested Pochard has been ringed
in low numbers in Europe and the largest
numbers of recoveries have been received
from birds ringed in Denmark, Germany, Russia and Spain. From the months
December February most recoveries are reported in western and southern Europe
and a few also in the area of the Black and Caspian Seas. A few recoveries are
reported in southern Russia and southern Siberia during the breeding season. A
concentration of recoveries is found in the Sea of Azov during autumn and this is also
known as an important wintering site for Red-crested Pochard. Birds breeding in
western Europe are partially migratory and move only short distances. Eastern and
southeastern European and Russian breeders winter in the area of the Black and
Caspian Seas, while birds breeding in Turkey and Azerbaijan winter in Egypt and
southwest Asia. The species is known to perform moult migrations and birds from
southern France gather in lakes in southern Germany and Switzerland, Principally the
Boden See (Lake Constance).

2.20 Common Pochard (Aythya ferina)
2.20.1 Numbers and distribution
There are large winter concentrations of Common Pochard in Central and West Asia,
especially around the southern Caspian Sea (Figure 2.44). A concentration exceeding
450,000 mixed Tufted Ducks and Common Pochards has been recorded in the Volga
Delta. The Wetern Black Sea region also holds very large numbers, and there are
many key sites in Turkey and the Balkans. In central and western Europe, important
centres of distribution are the lakes north of the Alps and The Netherlands. High
numbers are also found in Germany, France, Spain and the UK. In Africa the
wintering range extends to Morocco, Algeria, Tunisia, Egypt and Sudan.
The highest January counts have been recorded in Azerbaijan at Gyzylagach Nature
Reserve, where a peak count of 197,000 has been recorded, and at Kirov Bay where
93,300 were counted in 1991 (Table 2. 36). Counts exceeding 10,000 have been made
at a further four sites in Azerbaijan, making six in all. Counts at this level have also
been made at six sites in Turkmenistan, six in Iran, three in Kazakhstan and one in
Uzbekistan. Further west, the highest numbers have been recorded in the Black Sea-
East Mediterranean region, where more than 10,000 have been counted at 13 sites in
Turkey, most notably 47,833 at Beysehir Golu in 1996, 45,200 at Uluabat Golu in
1996 and 40,740 at Egridir Golu in 1999. In Romania, counts of 10,000 or more have
been made at nine sites, the most important of which are Portile de Fier Reservoir,
where 60,600 were counted in 1998, Chituc (Vadu Periboina) where there were
40,000 in 1993 and Razelm Northwest where 30,000 were counted in 1994. The
Limans and Bays of the Ukrainian Black Sea coast include seven sites where more
than 10,000 Common Pochards have been counted, including 43,000 in 1995 at
Dzansheisky (Shagany, Alibey and Burnas Limans), Skadarsko Jezero in Serbia-
Montenegro and Albania is a crucial site where 55,000 were counted in 1994, and in
Greece, of 5 sites where counts exceeding 10,000 have been made, Amvrakikos
Wetlands recorded the highest peak count, 22,850 in 1996.
The most important site in central and western Europe is the Bodensee in Germany-
Switzerland-Austria where 46,897 were counted in 1997, and three more sites in
Germany and three in Switzerland have recorded between 10,000 and 25,000
Common Pochards. Further north, Loughs Neagh and Beg in The UK recorded a peak
count of 38,998 in 1992, (but numbers decreased markedly in the 2000s) and in The
Netherlands, two sites recorded peaks of 20,000, Veluwemeer in 1999 and Ijsselmeer
in 1992. In France, peaks of between 10,000 and 16,000 Common Pochards have been
counted at six sites, the highest of which was 15,882 at Lac du Bourget in 2002. The
West Mediterranean region holds a number of important concentrations in Tunisia,
where Lac Ichkeul recorded 35,000 in 1998 and Lac de Bizerte 25,280 in 1994, in
Spain, where Laguna de Gallocanta recorded 38,960 in 1992, and in Italy where there
were 13,988 at Oristano in 1995.

2.20.2 Common Pochard movements
The Pochard breeds in the Palearctic,
from western Europe to north-eastern
China between 45°N and about 60°N. In
western and southern Europe, it is
present throughout the year, but
otherwise highly migratory. Wintering
areas spread out from western and
southern Europe through southern Asia
to Japan. In winter, it is relatively
widespread across central and north-
western Europe with major
concentrations in Germany, France, The
Netherlands and the UK. Other notable
concentrations occur in Switzerland, and
in countries around the Black and
Caspian Seas. Only small numbers are
found during winter in north Africa and
very few south of the Sahara.
Fairly low numbers of Pochard have been ringed in most countries and the largest
numbers of recoveries are from birds ringed in Switzerland, Britain and Russia. Most
of the recoveries during the period December to February are reported in western and
southern Europe, including Denmark and southern Sweden, as well as in northwest
Africa. A general decrease in recoveries from Western and Mediterranean Europe is
recorded between January and February, becoming more intense in March; return
migration continues in Russia in the east until May. Recoveries from the breeding
season (May June) are spread out from west Europe to about 75°E in Russia. A
strong concentration of recoveries is found in the Ob-Irtysh basin, east of the Urals
and north of Kazakhstan. The autumn migration starts in August and small numbers
of birds are still present in Russia in October. Pochards breeding in northern and
central Europe migrate to wintering areas in west Europe. Birds breeding in Britain &
Ireland are resident or move to the continent, as far south as Spain. West and central
Russian breeders move W to west Europe and Britain and birds breeding in southwest
Siberia and Kazakhstan migrate to the Caspian Sea, Black Sea and west to Italy.
Pochards breeding further east in Siberia and Central Asia winter in southwest Asia.
Moult migration in males occurs, but many of them remain and moult near breeding
sites. Several ringing recoveries of Pochards have shown that complex and aberrant
movements regularly take place.

2.21 Tufted Duck (Aythya fuligula)
2.21.1 Numbers and distribution
Tufted Duck has a similar distribution to Common Pochard, but is more concentrated
in Europe and less numerous in southern parts of the range around the Mediterranean
and in Iran (Figure 2.47). The biggest concentration of key sites is in the eastern
Baltic region including Denmark, eastern Germany, Poland and Sweden. Large
concentrations are found north of the Alps in France, Switzerland, Germany, Austria
and the Czech Republic, and The Netherlands and UK also hold large numbers.
Further East, the western and northern Black Sea regions are important, with large
numbers in Russia, Ukraine, Romania, Bulgaria and Turkey. The Caspian coast is
also extremely important with especially high numbers in Russia, Azerbaijan and
Turkmenistan. A concentration exceeding 450,000 mixed Tufted Ducks and
Common Pochards has been recorded in the Volga Delta.
Table 2.38 shows that the most important site in Europe is the Bodensee in Germany-
Switzerland-Austria where 82,542 were counted in 1996, and thirteen more sites in
Germany and five in Switzerland have recorded January counts between 10,000 and
60,000 Tufted Ducks. These counts include 58,912 at Lac de Neuchatel in 1994,
37,032 at Lac Léman in 1990, and in Germany, 50,000 at Wismar-Hohen
Wieschendorfer Huk, where 50,000 were counted in 1993, and the Grosser Plöner See
where 23,660 were counted in 1995. There were 28,931 at Cours du Rhin (France) in
January 1990, and two sites in The Netherlands recorded peak counts of around
28,700: Markermeer in 2000 and Ijsselmeer in 1992. A peak January count of 25,340
was made at Loughs Neagh and Beg in the UK in 1996 (but numbers decreased
markedly there in the 2000s).
The biggest concentration of important sites is in the eastern Baltic Sea where key
sites in Denmark include Roskilde Fjord, where 53,920 Tufted Ducks were counted in
1995, Maribo Soerne where there were 31,200 in 2000 and Sydfynske Hav where
20,992 were counted in 1994. Further east in the Baltic, the Neman river Delta in
Russia has recorded a peak count of 50,000, and in Poland there were 33,275 at
Jez.Dabie in 1993 and 17,898 at Zat. Gdanska in 1996. In southeast Europe, 80,000
were counted at Chituc (Vadu – Periboina) in Romania in 1993 and there were 40,000
at Skadarsko Jezero on the border between Montenegro and Albania in the same year.
Peak counts were made of 20,000 at Sasyk Liman, Ukraine in 2000 and 15,803 at
Burgas Lake, Bulgaria in 1992. The Turkish lakes hold fewer of this species than
Common Pochard, and the highest peak count was 14,550 at Hirfani Baraji in 1996.
Numbers are also lower in West and Central Asia than for Common Pochard, but
there are a number of key sites around the Caspian Sea. Gyzylagach Nature Reserve,
Azerbaijan is the most important of these, and a peak count of 81,000 was recorded
there. Peak January counts at five additional sites in Azerbaijan exceeded 10,000, and
there were six such counts in Turkmenistan, the highest at Lake Sarykamysh in 2003,
when 22,190 were counted. In Iran there were 16,744 at Lake Uromieh in 1997.

between 45°N and 70°N. A large
proportion (probably more than 60%)
breed in Russia (600,000 to 800,000
pairs) and neighbouring Fennoscandia
(147,000 to 220,000 breeding pairs). It is
mainly migratory, but some populations
in Europe are resident or perform only
short-distance movements. Wintering
areas are found in northwestern and
south Europe, around the Caspian and
Black Seas, northern Africa and across
Asia to Japan in the east.
The ringing of Tufted Ducks in Europe has not been widespread and the largest
numbers of recoveries available are from Britain, Switzerland and Denmark. During
December February recoveries are concentrated in west and central Europe,
including the southern and western part of the Baltic. A decrease in recoveries from
Iberia and SW France is recorded between January and February, with a tendency
which becomes more intense between February and March. The most intense phases
of return migration take place mainly during April and May. Recoveries during the
breeding season (May June) are spread out in northern Europe and eastward to the
River Ob, east of the Urals, at about 70°E. Some recoveries are also found during the
breeding season in west and central Europe as well as in Iceland. Autumn migration
continues until October and most Tufted Ducks have left the Russian breeding areas
by November.
Tufted Ducks are broad front migrants. Birds breeding in Fennoscandia, the Baltic
States and northwest Russia migrate to the Baltic and western and central Europe, a
few also to southwestern Europe. Central Russian and western Siberian populations
migrate to central and eastern Europe, the Black Sea, east Mediterranean and Caspian
Seas. Birds breeding in Siberia and in the eastern part of the breeding range winter in
the Caspian region, Pakistan, northern India, and southeast China to Japan.
Male Tufted Ducks from the east of the range begin arriving in western Europe to
moult shortly after breeding and return quickly after moulting. A second-year male
ringed at Abberton Reservoir, Essex, on 28 May 1969 was shot on 14 April 1971 in
Pakistan (6,153km). Such a record is probably not exceptional, and is almost certainly
an example of moult migration. Of 54 adult birds ringed at Abberton in the period
May-July and subsequently found in the same period, 50 were males. Of these, 34
were later found in Russia, with seven in Finland and only six found in Britain.

2.22 Northern Lapwing (Vanellus vanellus)
2.22.1 Numbers and Distribution
Northern Lapwings concentrate outside the breeding season in Ireland, the UK,
France and The Netherlands (Figure 2.50). Important numbers also winter further
south in Iberia, Italy, Albania and Greece, especially in hard winters. The Caspian
coast of Iran and Azerbaijan, and a number of sites in Iran and along the south and
east Mediterranean coast are less important wintering areas.
Peak January counts of Northern Lapwing exceeding 5,000 birds have been made at
37 sites in The UK, 33 in France, 20 in Ireland, 11 in Spain, 10 in The Netherlands,
four in Italy, two each in Russia, Albania and Iran, and at single sites in Greece and
Azerbaijan (Table 2.40). The highest counts were recorded at The Somerset Levels,
UK, where 78,762 were counted in 1995, and at the Etangs De La Brenne, France,
where 71,500 were counted in 2001. Additional sites in The UK where between
23,000 and 36,000 have been recorded are The Wash, Breydon Water and Berney
Marshes, Humber Estuary, Arun Valley, Ribble Estuary, Morecambe Bay, and
Thames Estuary. Equivalent sites in France where between 21,000 and 43,000 have
been counted were La Camargue, Marais Poitevin, Loire Amont, Etangs Argenton
Chateau, Sud Loire and Estuaire Seine. The highest count in Ireland, at the Shannon
and Fergus Estuary in 1995 was 27,924, and in Spain at the Riá De Villaviciosa in
1997 was 16,075.

2.22.2 Northern Lapwing movements
The Lapwing breeds in a large part of
Europe and in a band across Asia to
eastern China. The species is
migratory in most of its breeding
range, except western and
southwestern Europe and Turkey. It
seems to avoid areas where the winter
temperature falls below zero.
Large numbers of recoveries are
available from birds ringed in the
Netherlands, Britain, Belgium and
Sweden. Recoveries reported during
the period December to February are
strongly concentrated in western and
southwestern Europe as well as in
northwestern Africa. A decrease in
North African recoveries takes place
between January and February. The
distribution of recoveries in March shows further and stronger movements out of
North Africa and Iberia, and a higher concentration of recoveries in Italy. While
disappearing from North Africa, in March recoveries appear also in eastern Europe
and southern Scandinavia. In April recoveries are reported further north and east and
fewer recoveries are reported in France, Spain and Italy during this month. Recoveries
during the period May and June are spread out in central and northern Europe and a
few are also reported eastwards to Siberia and Kazakhstan. In this period large
numbers of recoveries are also found in Britain, northern France, Belgium, The
Netherlands, Germany and Denmark and they can be a result of summer movements
of adult birds directed westward from central and eastern Europe. The autumn
migration starts late and the number of recoveries in southwestern Europe and North
Africa is still increasing in December. Birds breeding in northern Europe and western
Russia migrate SW to western and southwestern Europe and North Africa. Lapwings
from breeding areas in western Europe are resident or move south, as far as North
Africa. Central European birds winter in western Europe, but also in the
Mediterranean. Birds breeding in central Russia and southwest Siberia can move to
southwestern Europe, but probably mainly to Turkey, Nile delta and western Asia.
Abmigration from western Europe to far east in Russia have been shown from
recoveries of birds ringed as chicks. Several recoveries show aberrant movements
westwards to islands in the Atlantic as well as to North America.

2.23 Black-headed Gull (Larus ridibundus)
2.23.1 Numbers and distribution
This is a very numerous species throughout western and southern Europe and it occurs
in high numbers deep into central Europe (Figure 2.53). The southeast Mediterranean
from Egypt to Israel and the southern Persian Gulf are also important centres of the
population in January. A number of concentrations in Central Asia and Iran are less
numerous than those found in Europe. Distribution extends to the West African coast
of Senegal, and in East Africa to Sudan, Ethiopia, Kenya, and Uganda.
Table 2.42 shows that a total of 33 sites in 11 countries have recorded January peak
counts of more than 20,000 Black-headed Gulls. Of these peak counts, 14 were in
France and Spain, where the highest was at Gravera Del Porcal, Spain, in 2000, where
96,000 were counted, followed by 80,000 in France at the Etangs Montpellierains in
1999. Other high counts in France included 70,180 at Etangs et Lacs du Bocage
Vendéen in 1998, 60,000 at Baie du Mont Sant Michel in 2003, and 38,500 at Baie de
Morlaix and Penze in 1997. Other high counts in Spain included 58,287 at Parque
Natural de la Albufera in 1993, 55,000 at Embalse de el Vicario in 1990 and 27,000 at
Embalse de Santillana in 1998. In Italy, seven sites recorded peak counts in excess of
20,000, the highest being 30,000 at Biviere di Lentini in 2002. In The UK, peak
January counts of more than 20,000 Black-headed Gulls were made at four sites,
including 50,000 at Tring Reservoirs in 1994, 35,410 in the Thames Estuary in 2001
and 31,300 at Lower Derwent Ings in 1996. Further East, single sites in Georgia and
Turkey recorded peak counts within this range, with 40,500 on the Black Sea Coast
between Batumi and Kobuleti (Georgia ) in 2002, and 30,990 at the Camalti Salt Pans
in the Gediz Delta (Turkey) in 1999. In the Middle East, a series of high peak January
counts included 64,543 at Lake Manzala, Egypt, in 1990, 40,065 on the Southern
Coastal Plain of Israel in 2002, 49,000 at Khor Khan, UAE, in 1991, and 27,747 at
Seeb-Qurm, Oman in 1991.

2.23.2 Common Black-headed Gull movements
This species breeds in a large area of the
Palearctic, from Iceland in the west to
Kamchatka Peninsula in the east and
north to about 65
o
N. The Black-headed
Gull is largely migratory, but winters
within the breeding range of western
Europe. The wintering range also covers
the Mediterranean, the area of the Black
Sea and Caspian Sea and coastal areas of
southwestern Asia and northeast Africa.
The species also winters in coastal areas
of eastern Asia and regularly in
Newfoundland and southeast Greenland.
The Black-headed Gull has been widely
ringed in Europe and large numbers of
recoveries are available from several
countries, among them Britain, the
Netherlands, Finland, Denmark, Sweden and Belgium. A large part of western and
southern Europe is covered by recoveries during
the period December to February.
The area includes Denmark and southern Sweden and the area of the Black Sea.
Winter recoveries are also found along the coast in North Africa and in the Middle
East. The return migration starts already in February and in March recoveries are
spread northward. In April recoveries are spread out around the Baltic and also further
east in Russia. During breeding season (May June) large numbers of recoveries are
found in western, central and northern Europe, most of them west of 45
o
E. In July
August, an increasing number of recoveries are found in southern Russia and Ukraine
and at the same time recoveries are also increasing in southwestern Europe. In
November, most Black-headed Gulls have left Finland and Russia, but in the east
recoveries are still reported in Ukraine. Birds breeding in Iceland are partial migrants,
moving to western Europe or to Greenland and northeastern United States, where two
recoveries were found. Birds breeding in northern Europe and northwestern Russia
winter in western Europe and south to North Africa. Western European birds and
birds breeding in central Europe are mainly sedentary or move south. Some Black-
headed Gulls breeding in Germany and Switzerland move south to the Adriatic Sea.
Birds from breeding areas in Russia winter in eastern Mediterranean and the Black
Sea area, while birds from southwest Siberia move south to the area of the Black and
Caspian Seas as well as Kazakhstan, Uzbekistan, Turkmenistan, Pakistan and India.

2.24 Black Tern (Chlidonias niger)
2.24.1 Numbers and Distribution
Russian and European breeding populations migrate almost entirely to sub-Saharan
Africa, where distribution is predominantly coastal (Figure 2.56). January counts are
concentrated along the west African seaboard from Senegal to South Africa and the
highest concentrations have been recorded in Namibia. Important breeding and
staging areas have been identified in Russia.
The highest January peak counts have been recorded in Namibia at Walvis Bay,
where 61,015 were counted in 2004, and Sandwich Harbour where 24,500 were
counted in 1998. In Russia, 15,000 have been recorded staging at the Neman River
Delta (Svazas et al. 2003) and 5,000 at Kyzlar Bay (Djamirzoyev et al. 2004). The
highest peak count in West Africa was recorded at Lac Nokoue, Benin, where 4,227
were counted in 1998. A total of 3,198 at Hadejia-Nguru, Nigeria, in 1999 is the
highest total from an inland site in Africa. Peak counts exceeding 1,000 were made at
four sites in Ghana, four in Benin and two in Gabon. The highest of these were at the
Densu Delta and at Keta Lagoon (both in Ghana) where totals around 2,400 were
counted in 1997 and 2002.

2.24.2 Black Tern movements
The Black Tern breeds locally in
continental Europe and eastward to eastern
Mongolia, between about 45°N and 55°N
and also in North America. The species is
migratory and birds breeding in the
Palearctic winter mainly along the coast in
West Africa, but also along the Nile in
Egypt and Sudan.
This species is ringed only in small
numbers in Europe and it is only ringing
carried out in Italy and the Netherlands
that has resulted in more than a few
recoveries. Recoveries from the winter
(November February) are reported
mainly from West Africa in Benin, Togo,
Ghana, Ivory Coast, Gabon and Senegal.
In April, birds are found in Italy and the
Netherlands and in May further east in Europe and in Siberia. During the breeding
season (June August) birds are spread out in central and eastern Europe, southern
Russia, southwestern Siberia and in northern Kazakhstan. In June, recoveries start to
appear in the Netherlands and in August also in southwestern Europe and
northwestern Africa. In October only a few recoveries of Black Terns are reported in
Europe. The migration mainly follows the West African coast, both in autumn and
spring, and only small numbers are believed to pass inland over the Sahara desert.
Birds from a large breeding area pass through the Netherlands during summer and
autumn and include birds from breeding areas as far east as southwest Siberia. During
spring, larger numbers seem to pass through Italy on their way to breeding sites in
central Europe and eastward to Siberia, indicating a loop migration.

2.25 Discussion: Outbreaks of HPAI in Europe and beyond in 2005-2006
The data provided in this report can be used in a number of ways. For example, they
can be used for locating high risk concentration and mixing areas of Higher Risk
species, and for interpreting, explaining and even possibly predicting outbreaks of
HPAI. In this Discussion we outline the outbreaks of H5N1 HPAI in Europe in early
2006, and use the Mute Swan Cygnus olor as an example. This was a key species in
outbreaks of HPAI H5N1 in Europe in 2005-2006 and a discussion of outbreaks
affecting this species sheds light on the role of wild waterbirds in the spread of the
disease in the winter of 2005-2006 and the following spring.
Numbers and distribution
There are two metapopulations of Mute Swan Cygnus olor in western Eurasia, divided
for the purposes of conservation management into five populations, as follows:
Population Population estimate Population trend
Mainland NW & Central Europe 250,000 Increasing
Britain 37,500 Increasing
Ireland 10,000 Unknown
Total, NW & Central Eurrope 297,500 Increasing
Black Sea 45,000 Increasing
W & Central Asia, Caspian 250,000 Increasing
Total, Central Asia & SE Europe 295,000 Increasing
Nearly all populations have been increasing for many years, although there are
indications of a decrease in numbers of birds wintering around the Baltic since around
1990, which may be related to reductions in numbers breeding in Sweden and
Lithuania. Recent information on the status of the Central Asia and SE Europe
population is lacking, and the estimates for these populations have not been changed
since 1996. Increasing numbers are wintering in the south of the range, for example,
the number of Mute Swans wintering in Italy in normal winters increased from fewer
than 500 in the early 1990s to nearly 2,500 in the early 2000s.
Most important countries and sites
The European country with the highest breeding population of Mute Swans is Russia
with 15,000-20,000 pairs. The following countries (in rough order of importance)
have an estimated 1,000-10,000 pairs: Germany, UK, Ireland, Finland, Netherlands,
Poland, Sweden, Denmark, Estonia, France and Lithuania. Romania has an estimated
750-1,000 pairs and all other countries are estimated to hold fewer than 1,000 pairs.
Mute Swans form some sizeable congregations during the winter months (See 2.8
above). The largest recorded by the International Waterbird Census (IWC) are on the
northern Black Sea coast of Ukraine, where 14,510 individuals were counted in the
eastern Sivash in January 2000, and on the Baltic coast of Denmark where 14,565
were counted at Lolland Northwest in January 1994. Counts in the Baltic have
decreased in recent years and 7,626 were counted at Lolland Northwest in January
2003. Between 1990 and 2004, 12 counts higher than 10,000 were submitted to the
IWC database, of which seven came from sites in Denmark and five from sites in
Ukraine. A count of 8,900 at the Meric Delta in Turkey in the cold weather of
227
January 1999 indicates how some birds from the Black Sea region migrate south in
response to abnormally cold winters.
Movements
The north-west and central European population is largely sedentary, except in the
east, where birds breeding in the Baltic region may move to the Baltic coast for the
winter, and may be pushed further west by unusually cold winters. Some Polish birds
move south and west into Central Europe for the winter.
The population found in Central Asia, southern and south-eastern Europe is more
migratory, but again, movements are strongly influenced by the severity of winter
weather. In most years, the bulk of the population breeding in the Black Sea region
migrates short distances from inland breeding sites to the northern Black and Azov
Sea coasts, although a small number of birds usually migrate further south to the
Danube Delta, Turkey, the Balkan Peninsula and southern Italy. Birds breeding in the
Caspian Sea region show a similar pattern of movement and most of the population
stays close to the Caspian shore throughout the year. In hard winters, large
movements of swans south to Azerbaijan and Dagestan have been recorded.
The outbreak of HPAI H5N1 in Mute Swans in southern Europe February 2006
The outbreak of HPAI H5N1 in Mute Swans appeared more-or-less simultaneously in
early February in Italy, in the southern regions of Puglia, Calabria and Sicily, in
northern Greece near Thessaloniki, and in Bulgaria in the northwestern Province of
Vilin and probably also Varna, on the Black Sea. The outbreak involved small
numbers of birds, but was confirmed as involving H5N1on 11 February. On 12
February, Slovenia also reported a suspected case of H5N1 in a swan on the border
with Austria.
Previous outbreaks in South & East Europe
Outbreaks of H5N1 were reported between October and December 2005 from Russia,
Romania, Croatia, Ukraine and Turkey. A majority of outbreaks in all these countries
involved domestic poultry, but wild waterbirds, especially swans were also involved.
At least 250 Mute Swans died of HPAI H5N1 in the Volga Delta on the north coast of
the Caspian Sea in November 2005 and considerable numbers (probably hundreds,
widely reported as being Whooper Swans) also died in the Danube Delta region of
Romania. Small numbers of Mute Swans also died at fish ponds in Romania and
Croatia in November 2005, where the use of infected poultry manure for fertilisation
was suggested as being a possible cause.
Possible causes of the February 2006 outbreak in swans in southern Europe
January 2006 was exceptionally cold throughout Eastern Europe and there is little
doubt that this caused cold-weather movements of Mute Swans to the southern and
western extremities of their normal wintering range. These outbreaks added to the
evidence that infected birds may be capable of migration. This population of swans
had already been infected with H5N1 earlier in the winter and it seems probable that
they then transported the disease to the secondary outbreak sites. Another possible
explanation is that the disease was spread by a different species, and that the swans,
being highly susceptible to HPAI and conspicuous when they die, and in these cases
weakened by unusually long migratory flights, acted as sentinels of the disease.
228
Development of further outbreaks
Later in February 2006, a Pochard near Lyons in France, and several dozen Mute
Swans in the East Baltic in Northern Germany, died of H5N1 whose origin was
impossible to explain. The spread to small numbers of Tufted Ducks in Sweden in
March seems likely to have originated from these infected wild birds in the nearby
southeast Baltic, an area where large numbers of these two species mix extensively.
Outbreaks in Africa
In Africa, the first outbreaks of H5N1 occurred in northern Nigeria in January 2006.
The spread to West Africa was attributed by some to wild waterbirds, with Garganey
Anas querquedula and Northern Pintail Anas acuta being suggested as likely vectors
because they migrate from areas of Western Siberia and west Russia affected by
earlier H5N1 outbreaks to West Africa, including wetlands in northern Nigeria. An
alternative explanation was that the outbreaks in Nigeria originated from trade in
poultry and poultry products. The origin of these outbreaks was not successfully
explained. By the end of April, cases had been reported in Burkina Faso, Cameroon,
Egypt, Niger, Nigeria and Sudan. These cases all involved domestic poultry, except in
Burkina Faso where only wild birds were affected, and Egypt and Nigeria where both
wild and domestic birds were involved.
The situation in Europe in May 2006
Figure 2.59 is a summary of the outbreaks of HPAI in wild birds in Europe between
January and early May 2006.
Figure 2.59: Source: http://ec.europa.eu/comm/food/animal/diseases/adns/index_en.htm#
By early May 2006, H5N1 HPAI had caused the deaths of wild birds in 13 Member
States of the EU. These countries were Austria, Czech Republic, Denmark, France,
229
Germany, Greece, Hungary, Italy, Poland, Slovakia, Slovenia, Sweden and The UK.
In France, Germany and Sweden, domestic birds were also involved. All outbreaks
were relatively small in scale, and all quickly died out or were quickly brought under
control.
The pattern of outbreaks involved most of the regions identified as holding
particularly important concentrations of sites with high numbers of wintering
waterbirds: The Black Sea-East Mediterranean region, The Southwestern Baltic, and
lakes north of the Alps. Beyond Europe, one of the biggest outbreaks among wild
birds was recorded in Azerbaijan, a country where extremely high numbers of
wintering waterbirds are counted. Subjective assessment suggests that H5N1 HPAI
outbreaks in wild birds were more prevelant in early 2006 in regions with a high
density of sites holding large numbers of waterbirds in winter. An exception to this
observation was the southern North Sea region, particularly The Netherlands and The
UK, which hold high numbers of wintering waterbirds, but where only one case of
H5N1 HPAI was recorded, in a Whooper Swan washed ashore in eastern Scotland.
The migration of millions of waterbirds from Africa and Europe, through Europe in a
northerly and easterly direction to Russia in March and April 2006 was predicted by
some to be a likely cause of an accelerated spread of outbreaks involving more
European countries. At the time of writing (early May 2006) the migration is almost
over, but the disease remains apparently rather dispersed in isolated parts of Europe.
Future risks
Swans are large, conspicuous birds living in open habitats, and dead birds stand a
relatively high chance of being found. If other species were affected by this
outbreak, the chances of finding corpses would be lower. The chances of an
outbreak being undetected might be quite high for some species, especially
inconspicuous ones which use densely vegetated habitats, such as Common Teal
Anas crecca.
Some Mute Swans associate closely with man, and the risk of infection of poultry
by this species and vice versa is probably higher than for most waterbird species.
The population of Mute Swans in eastern and southern Europe is usually wilder
than its northern and western European counterpart, however, and this risk
probably increased once the disease spread north into this population.
Mute swans are not highly migratory, but the populations affected by the
exceptionally cold 2005-2006 winter in eastern Europe will have migrated back to
the areas where some may have picked up the disease, and to their breeding range
further east and north in Europe, mainly in Ukraine and Russia. Most infected
birds would be expected to die, and the extent to which returning migrants will
take the disease with them depends on the proportion of the population that can
carry the disease without showing symptoms. This is currently unknown.
Another possibility is that waterbirds of at least 30 species, which will have
migrated north and east through infected parts of southern Europe in March and
April 2006 might have mixed with infected Mute Swans and become infected
themselves. It seems possible that these infected waterbirds of other species could
then have migrated to many parts of Europe, taking the disease with them. If this
230
had happened to a great extent during the spring migration in 2006, it is likely that
evidence in the form of dead birds would have been found. Unfortunately, the
extent to which this mixing of species might cause onward transmission, and the
species and sites that pose the greatest risk are not yet understood.
Even though the scale of the outbreaks during the spring migration of 2006 was
smaller than some experts predicted, it seems possible that the disease may persist
in some wild waterbird populations, and that these populations will continue to be
affected in future. The wetlands in the north European and Siberian breeding
grounds of many of these species apparently provide conditions favourable to the
survival and spread of HPAI viruses, and immature birds are thought to be more
susceptible to the disease than adults. It therefore seems possible that outbreaks of
HPAI in wild waterbirds will continue in the years to come.

3. Rapid assessment of ornithological data
at site level
3.1. Introduction
Outbreaks of H5N1 among wild birds usually occur at the level of wetland sites. They
often occur unexpectedly, confronting site managers with an emergency situation,
which demands quick action. Managers, together with local and national authorities
will have to take decisions with respect to restricting human use of the site,
monitoring bird mortality and sampling for virus prevalence. Any outbreak of H5N1
in a wetland site will also lead to a series of questions, which necessitate quick
answers.
Such questions include:
- How many birds are infected and which species are involved?
- Are there Higher Risk species present and in what numbers?
- Is there a special risk for transmission of the virus to poultry in the neighbourhood
and if so, which species can be expected to be involved?
- Are there endangered species present which might need special attention and/or
protection?
- Are there any neighbouring sites to which the virus might spread because they are
commonly used by the same birds?
- What is the position of the site in the flyways of migratory waterbirds and can any
prediction be made with respect to spread of the disease at a larger geographical
scale?
- What is the timing of migration for higher risk species occurring at the site?
Answering these questions makes it necessary to quickly analyse ornithological data
which might be managed by different organizations and/or individual ornithologists.
This chapter deals with the development of a Rapid Assessment Format for
Ornithological Data in case of an Outbreak of H5N1. Its aim is to give some guidance
to site owners and site managers to help them prepare for an outbreak of H5N1 in
their wetland area. Since wetland sites vary greatly with respect to size, habitat
characteristics, ornithofauna, human use and other aspects, the format provided is of a
very general nature. Its main purpose is to guide and stimulate site managers to
seriously consider possible future events, to prepare for an outbreak of HPAI, and to
develop a strategy in anticipation of the possible spread of the disease to their site.
3.2 Procedure followed
We first developed a draft Assessment Format by listing the following site-related
information and attributes which are considered to be fundamental in preparing for an
H5N1 outbreak:
1. General information on the site (location, size, ownership)
232
2. Short description of the general and ecological characteristics of the site
(accessibility, habitat characteristics, human use)
3. The occurrence of vulnerable bird species (status, numbers and seasonal presence
of higher risk species, species with a high “contact risk with poultry” and
endangered species)
4. Places with high concentrations of vulnerable bird species within the site
5. Local movements of vulnerable bird species to neighbouring sites
6. Position of site in flyway and consequences of bird movements for further spread
of H5N1
7. Human use of the site and its disturbance effects
8. The existence of poultry farms within a radius of 10 km of the site
9. Measures to be considered in case of an outbreak
10. Data sources
After the assessment format had been developed and guidelines for its use added, it
was tested for the following sites (Figure 3.1):
- National Park Schiermonnikoog (Island in the Wadden Sea in the north of the
Netherlands)
- The Camargue (Delta of the river Rhône in the south of France)
- Djoudj National Park (part of the delta of the Senegal river in the north of
Senegal)
- Eastern Sivash (system of lagoons and lakes bordering the Sea of Azov, Crimea,
Ukraine)
Figure 3.1: sites where the Assessment Format was tested, and for which
results are presented in this chapter.
233
The sites were selected on the basis of their different geographical locations on the
flyways of waterbirds migrating through Europe, as well as their different sizes,
abiotic and biotic characteristics. Further differences were that National Park
Schiermonnikoog and the Djoudj National Park were not under direct threat of an
outbreak of H5N1. In the Camargue, however, H5N1 had been recorded at a distance
of 50 km from the park in February 2006, and a series of outbreaks had taken place in
the Eastern Sivash in the period October 2005-February 2006.
The site assessments were compiled by Wetlands International staff from the offices
in Wageningen, Kiev and Dakar, in collaboration with the managers of the sites, and
by staff of the Biological Station at Tour Du Valat in The Camargue. Finally, the draft
format (presented as Annex 3.1) was adapted on the basis of the experience gained
with the different sites tested.
Ornithological data are often spread over different organizations and a variety of
“owners” may need to be approached in order to obtain all relevant data for a
particular site. In general, site managers will know best where relevant data can be
found. A number of international organizations manage large ornithological
databases, sometimes dealing with information about bird populations at a global
scale. Besides, in many EU member states some larger organizations either manage
national databases or might give guidance as to where relevant information might be
found.

3.3 Site assessments
3.3.1 National Park Schiermonnikoog, the Netherlands
1. General information
Name of site: National Park Schiermonnikoog
Country: The Netherlands
Coordinates: “53° 28’ N – 06° 11’ E
Size: 6800 ha
Managing organization: Vereniging Natuurmonumenten, Noordereinde 60,
1243 JJ ’s-Graveland, The Netherlands,
Tel: +31 (0)35-6559933
2. Short description of the site
Topography
The National Park Schiermonnikoog consists of the island of Schiermonnikoog and
parts of the North Sea and Wadden Sea adjacent to the island (see Figure 3.2). The
island measures 15 x 3 km. There is one village at the western end of the island with
approximately 1000 inhabitants. There are several houses in the dunes NW of the
village and in the Banckspolder, mainly used for recreational purposes. The island can
be reached from the mainland by ferry (3-5 times/day).
Schiermonnikoog is one in a chain of islands forming a barrier between the North Sea
and the shallow Wadden Sea. The Dutch Wadden Sea (total length 120 km) is
characterized by extensive tidal flats, intersected by numerous creeks and channels. In
the east the area is connected with the ecologically similar German and Danish
Wadden Sea together forming the International Wadden Sea.
Figure 3.2: Topography of the Island of Schiermonnikoog with national park boundaries and main
habitat types indicated
235
Habitat types
The main habitat types of the site are (see Figure 3.2):
- sandy beaches (along North Sea coast and at western and eastern tips of island)
- dunes (forming the central part of the island and situated in ridges parallel to the
North Sea coast (younger dunes) as well as directed from NW to SE (older
dunes))
- salt marsh with creeks (Oosterkwelder and Strandvlakte)
- grassland polder protected by dike in the south (Banckspolder, not included in
National Park)
- freshwater lakes (Westerplas, Kooiplasjes)
- duck decoy (Eendenkooi, at eastern edge of polder)
- pine forest (1e dennen and 2e dennen, north of village),
- tidal flats with creeks and channels (Wadden Sea, south of island).
Water depth, water temperature and hydrology
Water depth of the North Sea gradually increases in a northward direction with the 20
m depth line at 3 - 4 km from shore. The incoming tide enters the Wadden Sea
through channels east and west of the island. The Wadden Sea is intersected by
numerous creeks and channels of varying depth (maximum 10 m). About 70-80% of
the area consists of tidal flats which are submerged during high tide. Relatively high
water temperatures can be reached in shallow pools with stagnant water.

4. Places with high concentrations of vulnerable bird species
Breeding colonies
There are breeding colonies of Eurasian Spoonbill, Black-headed Gull, Common Gull,
Herring Gull, Lesser Black-backed Gull and Common Tern in dunes and saltmarsh
(see Figure 3.3).
239
Figure 3.3: Location of main breeding colonies of Common Gull Larus canus, Herring Gull Larus
argentatus and Lesser Black-backed Gull Larus fuscus (combined), Eurasian Spoonbill Platalea
leucorodia and Black-headed Gull Larus ridibundus on Schiermonnikoog (period 2001-2005).
Concentrations of resting, foraging or roosting birds
Geese and herbivorous ducks may forage in large groups in the polder and the salt
marsh Oosterkwelder. Geese spend the night on the Wadden Sea. Ducks also
concentrate at the fresh water lake Westerplas. Especially noteworthy are the
concentrations of hundreds of ducks (mainly Mallard) permanently present in the
duck decoy. Some of these ducks are (semi)-domesticated.
Species foraging on the tidal flats (mainly Shelduck, shorebirds and gulls) aggregate
in numbers up to more than 100,000 individuals on the various high tide roosts of the
island (see Figure 3.4).
Figure 3.4: Location of high tide roosts and main foraging areas for Common Shelduck Tadorna
tadorna and shorebirds and gulls Charadriiformes on Schiermonnikoog and the adjacent tidal flats of
the Wadden Sea.
5. Local movements of vulnerable bird species
Shelduck, shorebirds and gulls typically spread over the tidal flats at low tide, often
covering distances of 5 km or more from the high tide roosts. In the non-breeding
240
season, individuals of most species easily move to other parts of the Wadden Sea,
depending on food conditions. In this respect the Wadden Sea should be regarded as
an open system in which these species may freely move from one place to another,
using high tide roosts on different islands (or on the mainland), see Figure 3.5.
Geese (mainly Barnacle Geese) staging or wintering on the island may perform
foraging flights to preferred grazing areas on the mainland (areas inside and near the
embanked area Lauwersmeer, and the polder Anjumer Kolken, see Figure 3.5).
Figure 3.5: Location of main foraging areas on Schiermonnikoog as well as on the
mainland, commonly used by the same local population of Barnacle Geese Branta leucopsis.
In the period March-May Spoonbills which belong to the local breeding population
may forage in ditches in agricultural land in the provinces of Friesland and
Groningen, often covering distances of up to 25-30 km.
6. Position of site in flyway and consequences of bird movements for further
spread of H5N1
General position in flyway
The National Park Schiermonnikoog is situated in the East Atlantic Flyway which
connects arctic breeding grounds of waterbirds in Northern Europe, Siberia,
Greenland and East Canada with staging and/or wintering grounds in temperate
Europe and sub-tropical and tropical regions (North, West and South Africa). Most
waterbird species on Schiermonnikoog follow the coastline, moving in W-SW (205-
215 degrees) direction in autumn and in NE-E (25-35 degrees) direction in spring.
241
Ring recoveries
The EURING database has been searched for direct and indirect ring recoveries for
the 17 species analysed in detail in Chapter 2, the results being given in Table 3.5.
Maps are presented for Lapwing and Black-headed Gull (see Figure 3.6).

Recoveries for Greater White-fronted Goose and duck species are few and all situated
in NW Europe with five recoveries in autumn and winter from southern UK
(Common Teal (1), Mallard (3) and Northern Shoveler (1)). Recoveries for Lapwing
and Black-headed Gull are more numerous and fit well with the known main
directions of movement within the East Atlantic Flyway (Figure 3.6). For both
species, nearly all recoveries are in NE (spring and summer) or SW (autumn and
242
winter) directions. Again, a number of Black-headed Gulls have been recovered from
southern England.
Consequences of bird movements for further spread of H5N1
Shorebird species typically follow the Wadden Sea and any outbreak of H5N1 among
these species can be expected to spread within the international Wadden Sea,
presumed direction of spread to be determined by species ecology and season.
Shelducks perform moult migration and concentrate in numbers up to 100.000
individuals in the German Wadden Sea in July/August. Eider ducks moult in loose
groups more spread out in the Wadden Sea area.
Being rather opportunistic feeders, gulls may visit a variety of habitats, including
open sea, beaches, harbours, agricultural fields, open garbage dumps and urban areas
(mainly Black-headed Gull). This group may pose a special risk for spreading H5N1
to human settlements, but it is extremely difficult to predict any direction of possible
spread by this group.
Geese and herbivorous ducks could probably spread H5N1 to agricultural field or salt
marsh areas on other Wadden Sea islands or on the mainland. During severe weather
conditions geese may show “frost migration”. Barnacle geese usually migrate to the
south of the Netherlands and/or Belgium, whereas Brent Geese may move to southern
England (Kent) and France (Cote Picardy and Morbihan).
7. Human use of site and disturbance effects
Access to the public
Schiermonnikoog is a popular destination for tourists, with about 300,000 visitors
each year. From 15 April 15 July the dunes and salt marsh (whole area east of
Banckspolder) is closed to the public with the exception of the beaches along the
North Sea. Outside the above mentioned period the whole island is open to the public
with the exception of part of the dune habitat which is especially vulnerable to
erosion.
Hunting regimes
Hunting (mainly Rabbit, Brown Hare, Mallard and Pheasant) is limited to the polder
area (260 ha.) and the ridge of dunes nearest to the North Sea, which has a special
status for coastal defence (100 ha.). Hunting pressure is low.
Other human usage of site
The Banckspolder is used for farming (7 farms). In part of the Oosterkwelder,
extensive cattle, sheep and horse grazing occurs as a vegetation management measure.
There is small scale fishing in the creeks of the Oosterkwelder as well. Scientists of
Groningen University run several ecological projects on birds, observations focusing
on Oosterkwelder and tidal flats. There are two bird ringing stations, the duck decoy
(catching of ducks in October-January) and Groenglop (catching of passerines in July
- November).
243
8. Existence of poultry farms within a radius of 10 km of site
Density, location and nature of poultry farms
There are no (semi-) commercial poultry farms on the island, but a number of farms
and households keep small numbers of chickens and a few ducks and turkeys. These
are partly free roaming although they usually stay in the vicinity of human habitation.
At the edge of the village and the polder there is a small public farm which has been
especially created for children. The animals present (a dozen chicken, ducks and
geese) roam freely within a fenced area and are fed by the public.
Presence of other domesticated animals vulnerable to H5N1
There are numerous domestic cats on the island, some of which have escaped and now
live in the wild. A small number of pigs is kept by the municipality in the “children’s
farm” referred to above. A small number of inhabitants keep domestic goats, sheep or
horses.
9. Measures to be considered in case of an outbreak
Monitoring bird mortality
In case of an outbreak of H5N1 monitoring for dead and moribund birds should take
place at regular internals (preferably twice a week) and with a focus on higher risk
species.
Places to be inspected are:
- preferred foraging areas of geese (Banckspolder, Oosterkwelder)
- preferred foraging/resting areas of ducks (special attention to duck decoy)
- high tide roosts of shorebirds and other species foraging in the marine and littoral
zone (inspection of roosting places as well as the high tide line along the dike
south of the Banckspolder and the North Sea beach).
Monitoring activities should take place in such a way that disturbance of
concentrations of birds is kept to a minimum, i.e. visiting high tide roosts and high
tide lines at low tide.
Sampling wild birds for the occurrence of AI
The duck decoy, which is well equipped for catching ducks (ringing program) offers a
unique possibility to catch and sample Mallard and to a lesser extent also Northern
Pintail, Eurasian Wigeon and Common Teal for AI virus analysis. The duck decoy is
already involved in the Dutch AI sampling program.
Restrictions with respect to human activities in and near site
Restrictions should aim at minimizing the risk of further spread of H5N1, inter alia
through avoiding disturbance of wild birds.
Measures to be considered are:
- closing parts of the island to the public (Oosterkwelder, Westerplas, beaches, part
of Wadden Sea area)
244
- closing Berkenplas (fresh water pool in dunes) for swimming
- ban on hunting and bird catching/ringing activities
- ban on collecting eggs of Northern Lapwing (March-April)
- closing of the children’s farm
- keeping cats indoors
- keeping racing pigeons indoors
- ban on feeding birds in the village (it often attracts Black-headed Gulls)
- avoiding access of gulls to garbage (transhipment dump and garage barrels in
national park)
- restrictions with respect to the keeping and transport of poultry (conform
national/EU guidelines)
- restrictions with respect to the keeping of other vulnerable domesticated animals
(conform national/EU guidelines)
- informing the public (announcements on ferry, in hotels, on concentration points
for recreation and information leaflets distributed to all inhabitants).
A surveillance system should be put in place as well for some neighbouring sites, such
as the islands of Ameland and Rottumerplaat, the Lauwersmeer and surrounding
polders (concentrations of geese) and part of the Wadden Sea coast of Groningen and
Friesland.

3.3.2 Camargue (Rhône delta), France
1. General information
Name of site: Camargue (Rhône Delta)
Country: France
Coordinates: 43° 20’- 43° 43’ N / 04° 06’- 04° 51’ E
Size: 145,300 ha
Managing organizations: Conseil Général des Bouches-du-Rhône, Conseil Général du
Gard, SNPN, Conservatoire du Littoral, Parc Naturel Régional
de Camargue, Station Biologique de laTour du Valat, Les
Salins
2. Short description of the site
Topography
The Camargue, situated in the south of France, extends over an area of 145,300
hectares, between the gulfs of Aigues-Mortes in the west and Fos-sur-Mer in the east
(see Figure 3.7). The base of the delta is formed by 80km of sandy beach. The central
artery, the Rhône, divides into two arms near the town of Arles; the Grand Rhône,
which drains 85% of the land, and the Petit Rhône, which only drains the remaining
15% and tends to silt up at its mouth. These two arms divide the Camargue into three
sectors (from west to east, see Figure 3.7): the Petite Camargue, the Grande Camargue
(or Ile de la Camargue) and the Plan du Bourg. There is a network of roads connecting
the many farms, small villages and towns in the area. The town of Arles (50.000
inhabitants) is situated at the head of the delta.
Figure 3.7: Topography of the Camargue
246
Habitat types
The Camargue is of recent alluvial origin, gently sloping from north to south. The
northern part of the area (north of the Étang du Vaccarès) is characterized by a series
of alluvial ridges of riverine origin with fresh water marshes situated between the
ridges. The central part is largely covered by lagoons of varying salinity. The
southern part, which is periodically flooded, is characterized by saline lagoon
systems, formed by the sea. Habitat types are largely determined by hydrological
regime (degree of flooding) and salinity.
The following types can be distinguished:
- salt marshes and brackish lagoons
- freshwater marshes
- woodland
- meadows
- sandy beaches
- reed beds
- bare ground or salt-steppe, dry in summer and flooded in winter
- cultivated areas
The area under cultivation covers ca. 50.000 ha and consists mainly of rice and wheat
fields, vineyards, horticulture and arboriculture. In large parts of the area there is
extensive grazing by cattle, horses and sheep.
Water depth, water temperature and hydrology
The Ile de Camargue, which is situated between the two arms of the Rhône, is
completely surrounded by dikes, both along the course of the river and along the sea
coast. To serve the needs of agriculture, hunting and nature protection water levels are
managed by a combination of irrigation and drainage: each year about 400 million m3
of river water is pumped into to the area and distributed through a system of channels,
whereas about 200 million m3 is drained away. The area is divided into six
compartments in order to facilitate water level regulation.
3. Occurrence of vulnerable bird species at the site
Numbers and seasonal presence of higher risk species
Generalized figures of higher risk species in all months of the year are given in Table
3.6, showing that several duck species, Black-tailed Godwit, Ruff and Black-headed
Gull may occur in numbers exceeding 10,000 individuals. For a long period of time,
aerial counts have been made of swans, geese, ducks, coot and Black-tailed Godwit in
the period September-March. The results of the most recent count (season 2005-2006)
are presented in Table 3.7, showing that the total number of ducks, most of which are
higher risk species, may exceed 100,000 individuals.
247
Table 3.6: Numbers of higher risk species occurring in the Camargue in all months of the year. Numbers are generalized and
based on counts over a period of several decades. They should be read as follows: 1 = 1-10, 10 = 10-100, 100 = 100-1000, etc.
For more information on recent counts of swans, geese and ducks, see Table 3.7.

Occurrence of species of high conservation concern
Greater Flamingo breeds in the Camargue in numbers up to 15.000 pairs, which is about 50%
of the European population. Any outbreak of H5N1 in the breeding colony could be
disastrous for the European population. Breeding colonies of Eurasian Spoonbill, Glossy Ibis
and Squacco Heron are regarded of special conservation concern as well.
252
4. Places with high concentrations of vulnerable bird species
Breeding colonies
The Camargue hosts large numbers of colonially breeding waterbirds, such as Greater
Flamingo, herons, egrets, Pied Avocet, gulls and terns (see Table 3.10). During the
past decades Greater Flamingos have bred in Etang du Fangassier. Most other species
show less site fidelity and often change breeding places between years. Such
movements depend on environmental conditions such as flooding, food situation and
disturbance. Locations of breeding colonies and breeding numbers are assessed each
year by the Station Biologique de la Tour du Valat.

Concentrations of resting, foraging or roosting birds
In the non-breeding period, large numbers of ducks and Common Coot (up to more
than 100,000 individuals, see Table 3.7) concentrate in daytime in the various lake
systems within the area (especially Ligagneau-Vigueirat marshes in Plan du Bourg,
Tour du Valat (St. Seren), the Vaccarès and Consécanière in the Ile de Camargue).
Greater Flamingos winter in all of these areas and in the lower salinity saltpans. The
exact locations where major concentrations of waterbirds are found may change from
year to year and even from month to month. Greater Flamingos, swans, geese, ducks
and Common Coot are counted by aerial census on a monthly basis by staff members
of the Station Biologique de la Tour du Valat.
5. Local movements of vulnerable bird species
There are many local movements of waterbirds within the area which, however, very
much depend on food availability and thus change from year to year and between
seasons. Most prominent are movements of swans and geese between foraging areas
(agricultural fields and natural land habitat) and night roosts (on water bodies). Ducks
have a reversed diurnal rhythm, often being present on and alongside the lakes by day,
253
and performing foraging flights at night to feeding grounds (agricultural fields and
marshes) as far as some tens of km away. Herons and egrets spread over marshes and
water bodies in daytime, usually roosting together in trees. Gulls spread over a variety
of habitats, including urban areas (refuse dumps) and spend the night on open water.
The Greater Flamingo performs foraging flights from the colony up to 50 km away to
the Petit Camargue and Languedoc.
6. Position in flyway and consequences of bird movements for further spread
H5N1
General position in flyway
The Camargue is host to large numbers of birds throughout the year, most species
being migrants. The area is quite centrally-placed within the African-Eurasian region.
Ducks and shore-birds come from Northern Europe and Asia to winter in the
Camargue and elsewhere in the western Mediterranean, more than 30 species of
shorebirds transit the area twice a year moving between destinations as far apart as
Siberia and southern Africa while others, such as the Greater Flamingo, move around
the Mediterranean and West Africa, making the Camargue the most northerly part of
their range.
Consequences of bird movements for further spread of H5N1
The migrant species occurring in the Camargue cross the European continent in spring
on their way north and in autumn, on their way south, they either cross the
Mediterranean Sea or the Iberian Peninsula. Any outbreak of H5N1 among migrant
species could be expected to spread to other areas, these depending on the species’
ecology and season.
Shelducks from the Camargue perform moult migration (June-August) to the German
Wadden Sea, returning south again in winter.
Being rather opportunistic feeders, gulls may visit a variety of habitats, including
open sea, beaches, harbours, agricultural fields and urban areas, in particular rubbish
dumps. Waste from the city of Marseille is deposited at Entressen, close to the
Camargue, this being the largest open air dump in Europe. Gulls may pose a special
risk for spreading H5N1 to human settlements.
Ring recoveries
The EURING database has been searched for direct and indirect ring recoveries for
the 17 species analysed in detail in Chapter 2, the results being given in Table 3.11.
Maps are presented for Gadwall, Common Teal, Common Pochard and Black-headed
Gull (see Figure 3.8).

For nearly all species (also those not depicted in Figure 3.8) recoveries are widespread
but restricted to Europe, with a relatively small number of recoveries from European
Russia (Greater White-fronted Goose (1), Mallard (1), Common Teal (9), Eurasian
Wigeon (2), Northern Pintail (2), Northern Shoveler (2) and Tufted Duck (1)). Three
data points (Eurasian Wigeon (2) and Northern Pintail (1)) are situated in the well-
known moulting areas for ducks in the Volga Delta, northern Caspian Sea.
The data for Gadwall, Common Teal, Common Pochard and Black-headed Gull
(Figure 3.8) nicely demonstrate the connections between the Camargue and a large
number of sites all over Europe.
It should be noted that ring recoveries depend very much on human population
density and the likelihood that rings found will be reported. This might explain the
absence of recoveries for ducks from well-known wintering sites in North Africa,
especially the southern Mediterranean Coast, as well as from arctic and boreal
breeding grounds in Asia.
7. Human use of site and disturbance effects
Over one million tourists visit the Camargue each year, mainly from Easter through to
the end of summer. During the summer, visitors are concentrated on the beaches
wherever there is access to the sea. There is considerable leisure activity related to the
cattle and horses of the Camargue and the area is also a mecca for naturalists. Several
parks and reserves allow the public to approach wildlife.
256
Access to the public
Much of the Camargue is out of bounds to the public being situated within reserves.
Furthermore, there are private estates or properties not accessible to the public.
However, visitor facilities are available in various places with nature trails, hides etc.
Hunting regimes
Hunting pressure is high outside of the reserved areas (waterfowl, wild boar, rabbits).
Other human usage of site
Reed cutting
Fishing
Ricefields
Cattle and horses
8. Existence of poultry farms within a radius of 10 km of the site
Density, location and nature of poultry farms
No poultry farms. Few farms for ducks and pheasants to be released for hunting.
Households may keep small numbers of chicken (and a few ducks and turkeys).
Hunters use domestic ducks as decoys to attract wild ducks.
Presence of other domesticated (and wild) animals vulnerable to H5N1
Dogs (especially hunting dogs), cats in villages, Wild boar, Coypu are abundant and
tame.
9. Measures to be considered in case of an outbreak
Monitoring bird mortality (when and where)
In case of an outbreak of H5N1 monitoring for dead and moribund birds should take
place at regular intervals (preferably twice a week) and with a focus on higher risk
species. Monitoring activities should take place in such a way that disturbance of
concentrations of birds is kept to a minimum. If an outbreak occurs in summer, places
to be inspected should include the flamingo colony in the Salins de Giraud which
could only be done by the Tour du Valat team in association with the salt company,
and the colonies of tree-nesting herons which are all on private land. In winter,
inspections should focus on concentrations of swans, geese, ducks and common Coot,
places to be chosen on the basis of the most recent aerial survey.
Sampling wild birds for the occurrence of AI (where, which species)
The duck traps on the Tour du Valat are already being used to sample for AI virus and
for ringing surface-feeding ducks. This should be continued and intensified in case of
an outbreak.
Restrictions with respect to human activities in and near site (hunting ban, closed
areas, restrictions for keeping domesticated animals, etc.)
Restrictions should aim at minimizing the risk of further spread of H5N1, inter alia
through avoiding disturbance of wild birds.
257
Measures to be considered include:
- Closing part of the area to the public and minimizing other human use as far as
this may disturb bird concentrations
- Ban on hunting
- Restrictions with respect to the keeping and transport of poultry (conform with
national/EU guidelines)
- Restrictions with respect to the keeping of other vulnerable domesticated animals
(conform with national/EU guidelines)

3.3.3 Eastern Sivash, Crimea Autonomous Republic, Ukraine
1. General information
Name of site: Eastern Sivash (part of Sivash Lake)
Country: Crimea Autonomous Republic, Ukraine
Coordinates: N 45.255754 - 46.184015° – E 34.389325 - 35.470045°
Size: 1 650 km
2
(165 000 ha)
Managing organization: none
2. Short description of the site
Topography
The Eastern Sivash is the largest part of the Sivash Lake (Figure 3.8). It lies to the
south of the town of Genichesk and includes parts of Novotroitsky and Genichesk
Rayons (Kherson Oblast), and parts of Dzhankoy, Nyzhnyogirsky, Sovetsky,
Kirovsky and Leninsky Rayons (Crimea Autonomous Republic). The Eastern Sivash
covers much of the west coast of the Azov Sea on the north-eastern coast of the
Crimean Peninsula. All the different parts of the Eastern Sivash are joined together by
a system of narrow straits, and one strait in the east unites it with the Azov Sea. The
bay is shallow, saltwater, with an indented, mostly low-lying shoreline and numerous
spits and islets, as well as a large number of saline lowlands and peninsulas. It is
separated from the Azov Sea by a large, low-lying peninsula (Arabatska Spit), and has
only one narrow connection to the Azov Sea.
Habitat types
The main habitat types found in the Eastern Sivash are:
- Shallows and mud flats (situated along the coast line; mud flats are frequently
flooded or exposed under the influence of strong winds);
- Reed beds (mainly in shallow bays with constant or seasonal inflow of fresh
water);
- Sandy (or shell) banks, beaches and islets that cut smaller lagoons and bays off
from the main water area of the Sivash;
- Salt marshes in the depressions around the shallows and mud flats;
- Pastures, which generally surround fields or salt marshes;
- Agricultural fields (winter wheat, various crops) situated on the highest patches of
the terrain, most of them irrigated;
- Rice fields with dense network of irrigation canals make a distinctive artificial
habitat type.
Water depth, water temperature and hydrology
Waters of the Sivash Lake are generally shallow and rarely reach depths of 1.5- 2 m,
but water level varies considerably, depending on the season (in spring it is generally
higher) or time of day and/or wind force and direction. Fluctuations of water level
may range up to 1 m. Extensive areas are intermittently flooded or exposed under the
influence of strong winds. Just within several hours water is brought from one part of
the water body to another. Some shallows totally dry up during the hot season. Canals
259
Figure 3.8: Topography and location of the Eastern Sivash, and locations and sizes of
principal waterbird colonies
bring irrigation or drainage water to most bays. Salinity of water is generally lower at
the outlets of the canals. In summer, water temperatures may rise in shallows up to
27-30 degrees C. In extremely severe winters the water area becomes totally frozen,
while normally it stays clear of ice. Water temperatures in normal winters are around
0 - + 5 degrees C.

4. Places with high concentrations of vulnerable bird species
Breeding colonies
Most colonially breeding birds settle on the low-lying spits and islets in the northern
part of the Eastern Sivash (Figure 3.8), which is richer in aquatic feeding resources
than the southern part. Depending on the water level, colonies fluctuate in size and
species composition, but the most important ones are located in the same places every
year.

Eastern Sivash in 1998. For codes of colonies see Figure 3.8

Concentrations of resting, foraging or roosting birds
The Eastern Sivash is a large area. It is therefore difficult to count all waterbirds in the
area on a regular basis. Altogether 13 (near-)complete counts are available for the
period 1991-2005, carried out in January (8), April (2), August (2) and October (1)
(Table 3.14). These counts, together with other available data for the area, have been
used for an analysis of the integrated density of waterbirds (breeding, migrating and
wintering birds taken together) in the area in different seasons. Analysis used a spatial
database and involved creating a raster model and performing analyses with GIS
software. A summary of the results (integrated density all year round) is given in
Figure 3.9. The figure shows that most waterbird concentrations occur along the
coastline. High concentrations appeared to be related to food abundance and the
absence of hunting. The analysis has been used for identifying high risk areas for the
introduction and transmission of Avian Influenza as far as wild waterbirds are
concerned (see below).
266
Figure 3.9: Density of waterbirds at the Eastern Sivash in all seasons
5. Local movements of vulnerable bird species
Geese (White-fronted and Red-breasted) and to a lesser extent Mallards staging or
wintering in the area perform daily foraging flights to preferred grazing areas inland,
some of which are as far as 10-15 km distant. Distribution of shorebird gatherings
(especially Dunlin and Curlew Sandpiper) strongly depends on the water level at the
foraging sites in lagoons. They quickly move from flooded to exposed mudflats,
which are often situated at a distance of 10-15 km. Ruffs, which forage mostly on the
fields adjacent to the wetland, intensively move between feeding areas and
roosting/drinking sites on the coast. Gulls from breeding colonies or staging birds
(Slender-billed Gull Larus genei, Mediterranean Gull Larus melanocephalus) make
rather distant foraging flights to the fields and over shallows in various directions.
267
6. Position on flyways and consequences of bird movements further spread
H5N1
General position in flyway
The Sivash is a rather important staging area for arctic and boreal breeding species,
many of which use the Black Sea/Mediterranean Flyway both in spring and autumn.
This flyway connects the northerly breeding grounds with winter quarters in the
Mediterranean basin and Western Africa. For some species (White-fronted Goose,
some ducks) the Eastern Sivash is not only a staging, but also a wintering area.
Waterbirds passing the Eastern Sivash in spring head in E or ENE directions, many of
them stopping over in the Caspian Sea region and the extensive wetlands in Northern
Kazakhstan, SW and W Siberia before reaching their breeding grounds. During
autumn migration, waterbirds arriving from these regions concentrate in the Eastern
Sivash, some of them preparing for a long-distance flight in a southerly direction (as
far as South Africa), others undergoing primary wing moult (ducks) or taking a rest
before moving in SW-WSW direction to the Mediterranean basin or further into
western Africa.
Ring recoveries
The EURING database has been searched for direct and indirect ring recoveries for
the 17 species analysed in detail in Chapter 2, the results being given in Table 3.15.
Maps are presented for Mute Swan, Greylag Goose and Mallard (see Figure 3.10).

269
For most species the data available are few. Nevertheless a general pattern can be
distinguished which largely confirms the position of the Sivash described above.
The ringing data show migratory connections with:
- wintering areas in Western and Southern Europe (Greater White-fronted Goose,
Eurasian Wigeon, Northern Pintail, Garganey and Common Pochard)
- spring and autumn staging areas as well as presumed moulting areas along the
Black and Caspian Seas (Greylag Goose, Northern Pintail, Northern Shoveler and
Common Pochard)
- a large area situated NW-NE of the Sivash where most species of geese and ducks
can be expected either to breed or to pass on the way to/from their breeding areas
(most prominent in Greylag Goose and Mallard (see Figure 3.10).
Rather detailed information is available for Mute Swan Cygnus olor, which completes
its life cycle around the Black, Caspian and Aegean Seas. Breeding probably takes
place to a large extent in smaller inland wetlands, whereas staging and wintering is
concentrated along the shores of the Black and Aegean Seas. Wintering locations are
probably dependent on weather conditions, with cold weather movement taking place
in a SW direction when conditions are severe. This probably was the case when the
species unexpectedly appeared in the south of Greece and Italy, where it was
involved in outbreaks of H5N1 in the winter of 2005-2006
.
Consequences of bird movements for further spread of H5N1
There are well-known connections between the Caspian Sea and the Black Sea with
waterbirds moving from the former to the latter in reaction to cold weather.
Furthermore, there is an exchange of waterbirds between the Sivash and other
wetlands in the Black Sea area. Also in this case, waterbirds tend to move westwards
in reaction to cold weather. It is therefore believed that wetlands along the Black Sea
coast are directly at risk in case of an outbreak in the Sivash. In fact the Eastern
Sivash did already face a series of outbreaks of H5N1 in the winter of 2005-2006.
These outbreaks, which occurred in October, November and January were all related
in time with similar outbreaks in wetlands situated in the western part of the Black
Sea (Turkey and Romania). Although there is no firm proof that waterbirds spread the
disease in the area, there is a marked coincidence with their migratory movements.
Arctic shorebirds occurring in the Sivash (e.g. Dunlin and Curlew Sandpiper) might
potentially spread H5N1 to other wetlands in the Mediterranean basin and into Africa.
Ducks, Northern Pintail and Garganey in particular, might be involved in the spread
the disease to wetlands in sub-Saharan West Africa.
Frequent changes of water level in the Eastern Sivash facilitate mixing of different
species of waterbirds and their movements to the small freshwater ponds on the coast,
where they can easily come into contact with domestic birds. In mild winters White-
fronted and Red-breasted geese move daily between roosts and grazing areas,
increasing the risk of spreading the disease inland in the radius of 10-15 km of the
roosts. As everywhere else, gulls may play a linking role in the spread of disease
carrying the virus from concentrations of waterbirds to various water bodies
frequented by domestic birds, but their movements in search of food are hardly
predictable. In August, when their numbers reach a maximum, many gulls and terns
270
forage over agricultural fields and come close to the settlements, roost on the ponds in
the villages or nearby. In winter, during severe weather conditions, parts of the
Eastern Sivash with low salinity may freeze up and then waterbird concentrations
move to the hypersaline water areas in the southern part of Eastern Sivash and Central
Sivash. In the extremely severe winter of 2006 the Sivash became totally frozen and
all wintering waterbirds concentrated along the southernmost coast of the Crimean
peninsula.
Occurrence of outbreaks of H5N1 in the winter of 2005-2006: predicting areas of
special risk
A series of outbreaks of H5N1 occurred in the Eastern Sivash in the winter of 2005-
2006. The first outbreak was recorded in October in the village of Nekrasovka which
is located next to one of the most important waterbird concentration areas in the
Sivash. Many of these waterbirds (especially Greater White-fronted Geese and
Mallards) forage on the agricultural fields near the village where they mingle with
domestic ducks. A second outbreak occurred in November, shortly after a cold spell
had brought thousands of waterbirds to the area, among which were 15.000 Greater
White-fronted Geese. A third outbreak took place in mid January. At that time the
Volga delta had become totally frozen. This resulted in large numbers of waterbirds
leaving the Caspian Sea area, visiting the Eastern Sivash, after which they were forced
further westwards by freezing conditions.
It follows from the above that the onset of outbreaks could in all cases be related to
the existence of waterbird concentrations or major migratory movements of these
birds. After a “new outbreak” had started, there was usually a series of “satellite
outbreaks” which were often away from the larger concentrations of wild waterbirds.
An analysis of the chronology of the outbreaks, their distribution and the
circumstances under which they took place led to the hypothesis that three major
environmental factors might be involved: (1) the presence of wild waterbird
concentrations; (2) the presence of irrigation canals and other small freshwater bodies
near human settlements which might be a source of contact between wild and
domestic birds, and (3) the density of the human population, as a reflection of the
distribution of free roaming poultry.
Shortly after the second outbreak had taken place, an attempt was made to indicate
areas with varying degree of “outbreak risk” on the basis of the above factors using
spatial modelling as applied for the integrated bird density (see Figure 3.9). This time
all three factors mentioned above were integrated. The analysis resulted in a map
indicating areas of medium, high and very high risk which is indicated in Figure 3.11.
The figure shows that most outbreaks were indeed located in the areas of highest and
high risk. Two outbreaks which appeared after the analysis had been made (indicated
as “predicted” in the figure) were also in or next to a high risk area. The analysis
shows that spatial modelling might be a useful tool for indicating areas at risk for
outbreaks of H5N1.

7. Human use of site and disturbance effects
Access to the public
The coast of Eastern Sivash has a low human population density. Most villages are
concentrated along the North Crimean Canal and its branches, although some
populated places are situated right on the coast close to places of seasonal
concentrations of waterfowl. There is no public access limitation over most of the
area, except for some hunting grounds during the season, and private fish-ponds. The
Crimean coast of the Eastern Sivash is visited by a small number of local people who
work on the adjacent fields, and also by hunters and fishermen. In the northern part of
Arabatska Spit (south of Genichesk) there are some resorts, which are gradually
recovering after the post-Soviet period and enjoy increasing numbers of visitors each
year. Roads over most of the Eastern Sivash coast lack any paving and many areas are
rather difficult to access.
Hunting regimes
Hunting (waterfowl, Pheasant, Quail, Grey Partridge, Brown Hare, Red Fox) is
allowed in autumn (according to Ukrainian hunting law only on Tuesdays and at
weekends). Waterfowl are hunted from mid-August till December; mammals - during
winter. Hunting areas are divided among local hunters’ associations and clubs. Access
to the hunting grounds in leasehold of private hunting clubs is limited. Hunting
pressure is medium, but poaching is rather widespread.
Other human usage of site
The local agriculture is primarily horticultural. Eighty per cent of the area is occupied
by arable land; the remainder is occupied by orchards (2.2%), vineyards (1.2%) and
fallow land (1.2%). Almost half of the cultivated land is under irrigation. Pastures
272
comprise more than 13% of the area. Mostly cattle and sheep are bred. Commercial
fisheries have lost their importance over the last decade and only amateur fishermen
catch fish in the Sivash and some small rivers that flow into it. Some bays of the
Sivash have been turned into fishponds where carps are bred.
8. Existence of poultry farms within a radius of 10 km of site
Density, location and nature of poultry farms (chickens, ducks, turkeys)
An ostrich farm (300 birds) is located south of Strelkovoe village. Ostriches are kept
in a fenced area under the open sky and are at risk of exposure to wild birds.
Villagers throughout the Eastern Sivash commonly keep chickens, ducks geese and
turkeys. Official statistics were shown to underestimate the numbers of poultry in the
private sector. During the epizooty of H5N1 in winter 2005-2006 a total of 29,135
birds were culled in 2,228 households in infected villages. This gives an average of
around 13 birds per household, which is 5 times lower than figures reported by the
veterinary service. Free roaming used to be a widespread practice throughout the
region; poultry and other domestic animals are often kept together. Domestic geese
and ducks also used to visit ponds, rivers, canals and artesian wells in the vicinities of
villages. As the number of freshwater sources is limited, birds from different
households often concentrated in these places, which were frequently visited by wild
birds as well. Currently, the local veterinary service is making efforts to ensure that
people keep poultry indoors and maintain basic rules of biosecurity.
Presence of other domesticated animals vulnerable for H5N1 (cats, pigs)
In the villages around Eastern Sivash cats and dogs are kept in nearly every
household. Villagers also keep pigs, sheep, cows and horses. There are commercial
herds of sheep and cows.
9. Measures to be considered in case of an outbreak
Monitoring bird mortality
In case of an outbreak of H5N1, monitoring for dead and moribund birds should take
place at selected parts of the coast (Dzhankoi bay, sea side of Arabatska Spit) and
several islands and spits (Tup-Tarkhan peninsula, Koyanly Islands, Cjongar Islands)
with a focus on higher risk species. Staff of the Azov-Black Sea Ornithological
Station should be involved. As the distances to walk along the muddy coast-line are
rather large, bird mortality monitoring is feasible on a weekly basis only.
Sampling wild birds for the occurrence of AI
Staff of the Azov-Black Sea Ornithological Station in Melitopol have extensive
experience of catching waders in this area. Mist-netting of shorebirds (Ruff, Curlew
Sandpiper, Dunlin, Broad-billed Sandpiper, Little Stint) can be easily organised at the
known suitable localities in April, May, August, September and October. Possibilities
for catching ducks and other species have yet to be investigated. Fresh faeces from
cormorants, gulls and terns can be collected in sufficient numbers at roosts and on the
colonies. In winter, fresh droppings can be collected from White-fronted Goose at
grazing sites.
273
Restrictions with respect to human activities in and near site
Restrictions should aim at minimizing the risk of further spread of H5N1, inter alia
through avoiding disturbance of wild birds.
Measures to be considered are:
- ban on hunting and control of bird catching/ringing activities
- keeping cats and dogs indoors
- ban on collecting Nereis worms (local fishermen commonly collect Neris
diversicolor on the mudflats, where waterbirds forage)
- restrictions with respect to the keeping and transport of poultry (conform with
national/EU guidelines)
- restrictions with respect to the keeping of other vulnerable domesticated animals
(conform with national/EU guidelines)
- informing the public (local press, on the road upon entering Crimea, information
leaflets distributed in the villages).

3.3.4 Djoudj National Park, Senegal
1. General information
Name of site: Djoudj National Park
Country: Senegal
Coordinates: 16° 30’N and 16°10’W
Size: 16000 ha
Managing organisation: Direction des Parcs Nationaux du Sénégal
National Parks Department P.O. Box 5135, Dakar-Fann, tel.
+221 832 2309
2. Short description of the site
Topography
Djoudj National Park is a large wetland in the Senegal River Delta (Figure 3.12).
Some dunes with Tamarix vegetation lie in the North-east and in the south of the park.
There is also a small dune system in the centre. There is no settlement inside the park
but 7 villages are located in the buffer zone with a total population estimated at 3,800
individuals.
Djoudj national Park is one element of the complex of wetlands in the Senegal River
delta (e.g. Diawling National Park, Mauritania, and Les Trios Marigots, Djeuss
Marigot, Ndiaël Ramsar Site and Guembeul Reserve, Senegal). Djoudj is regularly
flooded by fresh water coming mainly from the Senegal River through two dams, the
Djoudj and Crocodile infrastructures.
Djoudj can be reached by car from Saint-Louis, regional Capital after 60km and from
Ross Béthio at a distance of 15 km. Djoudj is a tourist destination and in some
seasons, light aircraft can land at the small airport. Djoudj is open for tourism during 8
months from October to the end of May.
Figure 3.12: Topography and Vegetation types in the Djoudj national park
275
Habitat types
The main habitat types of the site are indicated on the vegetation map (Figure 3.12).
About 80% of the total area is permanently flooded, providing excellent habitat for
waterbirds for resting, foraging and nesting. The vegetation is mainly Typha on the
western side, Phragmites in the centre and widely, Sporobolus sp. In the open water,
there are two species of Water lilies, an important source of food for ducks and geese.
The dunes are located in the south covered mainly by Tamarix vegetation.
Water depth, water temperature and water hydrology
The main river, called Djoudj, is 1.8 m deep between November and January. The
water level decreases from February to June and the surrounding wetlands become
completely dry.
The minimum temperature between January and August varies from 13° to 25°C,
and the maximum from 30°C to 39°C between February and March.
The Flood gates of the Djoudj River and Crocodile River control the water level in the
park with the aim of maintaining optimal breeding success and feeding conditions for
waterbirds.
The water level determines the quality and the quantity of food available to
waterbirds, and also determines the ecological character of the park
3. Occurrence of vulnerable bird species at the site
Numbers and seasonal presence of higher risk species
Table 3.16 shows the Higher Risk species identified in Chapter 1 that occur regularly
at the Djoudj. The most numerous of these are (in order of abundance) Garganey,
Ruff, Northern Pintail and Northern Shoveler. Two species in Table 3.16 are Globally
Threatened according to IUCN Criteria: Marbled Teal, which is Vulnerable and
Black-tailed Godwit which has recently been classified as Near-Threatened.

count)
- African Pygmy Goose Anas auritus: 40 non-breeding individuals (January count)
- Marbled Teal Marmaronetta angustirostris Irregular non-breeding visitor in small
numbers.
4. Places with high concentrations of vulnerable bird species
Breeding colonies
There are extensive colonies of Great White pelican, Wood Ibis, Knob-billed Goose,
White-faced Tree Duck, Egyptian Goose, Spur-winged Goose, African Spoonbill,
Sacred Ibis , Black-crowned Night Heron, Grey Heron, Little Egret, Great White
Egret, Great Cormorant, Long-tailed Cormorant and African Darter (see also Figure
3.13).
Concentrations of resting, foraging or roosting birds
Northern Pintail, Garganey and Northern Shoveler may rest or forage in large groups
at Grand Lac, Khar marsh and on Thieguel River and in its surroundings. During
night time, they leave the park to visit Senegal River Marshes for feeding.
The White-faced Whistling Ducks aggregate in numbers up to 10,000 on the Djoudj
river, at Grand Lac and at Khar river and lake (see Figure 3.13).
Ruffs and Black-tailed Godwits aggregate in large groups in Grand Lac and
surroundings for resting and roosting.

278
5. Local movements of vulnerable bird species
Pintails, Shovelers, Garganeys, Ruffs and Black-tailed Godwits often move locally
between Djoudj marshes and surrounding wetlands. Ruffs and Black-tailed Godwits
usually forage in the rice fields in the northern part of the park as well as elsewhere
along the Senegal river. At a local scale, a number of wetlands in the lower Senegal
delta are often used by the same bird populations for feeding and roosting. The
distribution of these birds appears to be primarily determined by the presence of food,
water (flooding) and safety (hunting, predators). See also under 6.

Position of site in flyway and consequences of bird movements for further spread
H5N1
General position in flyway
The Djoudj National Park is situated in the East Atlantic Flyway in the Sub-Saharan
zone. It connects breeding grounds of waterbirds situated in Greenland, Europe,
Western and Central Asia with West African wintering grounds as far south as South
Africa. Most northerly breeding waterbirds staging or wintering in the Djoudj make
use of additional staging areas situated along the Atlantic coast of Europe and North
Africa, or in the Mediterranean basin. Migratory waterbirds visiting the Djoudj
usually follow the coastline, moving in N-S directions. However, there are also
migratory movements in E-W directions, between the Djoudj and other West African
flood plain systems, such as the Inner Niger Delta and Lake Chad. Some species like
Garganey and Ruff may perform so-called loop migrations, flying southward through
the western Mediterranean in autumn, and returning northward through the Central or
Eastern Mediterranean in spring.
Ring recoveries
The EURING database has been searched for direct and indirect ring recoveries for
the 17 species analysed in detail in Chapter 2, the results being given in Table 3.18.
The data are sparse and only those for Garganey have been depicted (Figure 3.14).

Figure 3.14: Direct and indirect ring recoveries for Garganey Anas querquedula ringed or found in the
Djoudj (EURING database).
For the species mentioned recoveries are spread over Europe and Russia as far east as
SW Siberia (Northern Pintail). There is one exception of a Garganey being recovered
in the Inner Niger delta (Figure 3.14). These data are in line with the position of the
Djoudj in the East Atlantic Flyway and the existence of a connection with West
African flood plains.
Consequences of bird movements for further spread of H5N1
Waterbird movements connect the Djoudj National Park with several other wetlands
in the West African region.
The following connections are highly relevant with respect to threat spreading H5N1:
- Shorebirds, Eurasian breeding ducks and African ducks aggregating in the Djoudj
frequently use other wetlands in the lower Senegal Delta for feeding. There is also
a regular exchange of birds between these wetlands depending on water level,
food abundance and safety.
280
- Movements of Greater Flamingo, Northern Shoveler, Garganey and Northern
Pintail have been shown to connect the Djoudj with Mauritania (Diawling and
Banc d’Aguin), The Gambia, Guinea Bissau, Guinea and Mali.
- Outside the breeding season, Great White Pelicans breeding in the Djoudj often
visit other Senegalese wetlands as well as wetlands in Mauritania (Banc d’Arguin
National Park, Diawling National Park, Chott Boul Reserve).
- White-faced Whistling Ducks breeding in the Djoudj spread to other wetlands in
the Senegal Delta, Mauritania and Mali after breeding.
- Knob-billed Ducks perform moult migration and may gather in the Djoudj in large
numbers (maximum number 8993). After moult has been completed these ducks
may be found foraging in rice fields along the Senegal river and the Niger river.
- It may be concluded from these data that any outbreak of H5N1 can potentially be
spread by wild waterbirds within the West African region, especially in the lower
Senegal Delta (Senegal-Mauritania).
7. Human use of site and disturbance effects.
Access to the public
Djoudj National Park is a popular and international destination for tourists with
15,000 visitors per year. The park is open From October to the end of May.
Hunting regimes
Hunting is mainly organised in the surrounding zone to the north-east and in the
south. Shovelers, Pintails, Gargeneys and African ducks can be hunted. Shooting of
these species is allowed in the morning and in the evening. These limitations restrict
hunting pressure.
Other human usage of site
The local human populations have access to the park throughout the year to find lost
domestic animals and to gather materials to make hats or carpets. In the buffer zone,
the rice fields are the main livelihood of the local population. Fishing is forbidden in
the park but from time to time poachers are arrested inside the park. Cattle grazing is
not controlled.
8. Existence of poultry farms within a radius of 10 km of site
Density, location and nature of poultry farming
There are no commercial poultry farms within a radius of 10 km. The inhabitants of
the Djoudj area keep small numbers of chickens and a few ducks which stay in the
vicinity of human habitation.
Presence of other domesticated animals vulnerable to H5N1
There are few domestic cats or dogs in the eight villages surrounding the park, and
pigs are not kept.
281
9. Measures to be considered in case of an outbreak
Monitoring bird mortality (when and where)
- In case of an outbreak of H5N1 monitoring for dead birds and moribund birds
should take place at regular intervals (three times a week) and with a focus on
higher risk species.
- Places to be inspected are:
- Preferred foraging/ resting areas of ducks (more attention for national committee
for Avian Influenza: CONAGA).
- Preferred foraging/ resting areas of shorebirds and other birds foraging in the
lower flooding areas.
- Monitoring activities should take place in such a way that disturbance of
concentrations of birds is kept to a minimum.
Sampling wild birds for the occurrence AI
CONAGA in partnership with the ACTS (the Senegalese association of hunting and
shooting) should ensure the catching of ducks, to sample Shovelers, Pintails,
Garganeys, and Ruffs for AI virus analysis.
CONAGA is already involved in the AI sampling programme with CIRAD.
Restrictions with respect to human activities in and near the site
- Closing the park to the public (visitors and local inhabitants).
- Ban on hunting.
- Restrictions with respect to keeping and transport of poultry(conform national and
international guidelines).
- Restrictions with respect to the keeping of other vulnerable domesticated animals
(conform national and international guidelines).
- A surveillance system should also be established for neighbouring sites, such as
the rice fields, the Trois Marigots, Diawling National Park and Djeuss area.

4. Future Work
The bulk of interpretation in this report is from two major databases, the International
Waterbird Census (IWC) and the EURING database. In this preliminary assessment,
we have provided an overview of the available data and have described the broad
patterns in the abundance and movements of a selection of the higher risk species. In
addition we have provided examples of the kind of information that can be rapidly
brought together to describe the risk of an outbreak in a site spreading to other areas.
With such a broad analysis, it is inevitable that there will be gaps in our knowledge.
These gaps can be filled in three ways: by more specific analysis of the existing data,
by adding to or modifying the way the data are collected, or by developing novel
techniques to determine with confidence how wild birds might spread the H5N1
throughout Europe.
The species dealt with in this report cover only a proportion of the species
that are at risk of spreading H5N1. To fill this gap it would be necessary to
expand the current analysis to other species, including short-distance intra-
European, Asian and African migrants and also to other taxonomic groups.
IWC counts have traditionally concentrated on wintering sites but large
concentrations of birds can gather at different sites in spring and autumn.
Collecting more detailed information on stop-over sites used in autumn and
spring, in particular the timing of occurrence and the numbers of higher risk
species present at any one time. For example, do species X and Y overlap in time
and space? This can be achieved by further analysing the IWC database and
identifying gaps, which could be included in the IWC program in future.
Establish a system for mortality monitoring and assessing ‘normal mortality’.
Baseline data need to be gathered to pick up exceptional mortality as different
from ‘normal mortality’. Little is known about this at present. Existing data
gathering networks can be engaged in gathering this type of information.
At the current level of analysis only broad patterns in migration routes have
been identified and not the precise routes or timing of migration. We propose
analysing the EURING data to understand better the direction and movements
from individual regions within Europe. For example, the current analyses indicate
a general direction of movement but contained within this is probably more than
one migration route. We would develop smoothing techniques to identify the main
directions of movement on a regional basis (e.g. one degree grid cells) and
describe the phenology of migration. This could involve detailed analysis of
ringing and count data for one, two or more Higher Risk species, in order to
describe movements in space and time.
One of the major gaps in our knowledge is identifying which sites and species
are the most likely to be involved in the spread H5N1 between flyways.
Identifying sites that bridge the gap between flyways can be done from ringing
recoveries. For example in this report, it has been shown that different populations
of several species mix in the eastern Sivash (Greater White-fronted Goose,
Mallard, Eurasian Wigeon, Pintail, Teal, Garganey and Pochard) linking the East
Atlantic flyway with the Black Sea/Mediterreanean flyway, whereas analysis of
283
the recovery data from Schiermonnikoog indicated that only one population of
each species was involved.
Strategies for long-distance migration are poorly understood for many
wildfowl species. Migration strategy may also impact the ability of a wild bird to
spread H5N1. Some species may migrate in short-hops whereas others migrate in
long-distance jumps. We would aim to identify migration strategies for the high
risk species and determine length of flights and stopover-times where possible
from the literature. We would also specifically analyse EURING data to identify
those species that undergo moult migrations and, in conjunction with IWC count
data, determine the important moulting areas for particularly ducks, geese and
swans, with the longer-term aim of developing the survey program to provide
better count coverage of these sites at appropriate times.
Analysis of "contact risk with poultry" for "bridge species". We know little
about this for Europe and virtually nothing for Africa. This would involve survey
work around poultry farms to identify the species that come into contact with
poultry and determine the kind of behaviour that determines risk. Included within
this would be survey work around outdoor pig farms as pigs can be a carrier as
well.
In relation to trans-European migrants, we know very little about European-
Afrotropical migration systems, which is important as it is a key potential
source of H5N1 reaching Europe. Knowledge is limited in part due to low
ringing effort in Africa and also a low reporting rate of hunted birds. Initiation of a
wildfowl ringing programe in key sites, e.g. Djoudj, where major passerine
ringing activities have taken place before (but also sites in Mali, Nigeria & Chad
and along the rift valley and coastal east Africa) would greatly improve our
knowledge of movements of birds to and from these areas. The IWC data could be
used to determine concentrations of waterbirds and sites, which may be suited for
catching activities. In conjunction with the point above, collation of recovery data
generated from within Africa (using data from the various African Ringing
Schemes under the auspices of AFRING) would be necessary to describe
movements of intra-African migrants.
Identify the degree to which individual species deviate from the general
migration patterns identified in this report. The major directions of movement
have been identified for the species covered by this report. However it is
important for tracking the potential spread of H5N1 to specifically look for
species that show exceptions to these general movements, e.g. movement between
flyways between years, exceptional movements, etc. To determine which species
are more or less likely to show unusual movements, will require the development
of statistical methods to objectively analyse the degree of abnormal movements
using EURING data.
To determine the linkages between wintering, breeding and moulting areas
may require other novel techniques to be used. A method using stable isotopes
in flight feathers has been used to successfully track shorebird migration in South
and North America (Atkinson et al. 2005) and trace element analysis has been
used in Sand Martins. Satellite tracking is now available for many waterbird
species and could be a valuable tool to fill in gaps in our knowledge of bird
movements.

Annex 1.1
Evaluation of species considered to pose a high risk of carrying Asian
H5N1 lineage
Evaluation of migratory waterbird species which pose a relatively high risk of
spreading Asian lineage H5N1 to and within the European Union. Only species
belonging to the orders of the Anseriformes and Charadriiformes, which migrate from
outside the EU to within EU borders are included. Codes used for bahaviour/ecology
are explained in Section 1.3. Codes used for migration behaviour are Y (yes) and N
(no). Codes used for contact risk with poultry are 0 (no risk), L (low risk), M (medium
risk) and H (high risk). Higher risk species are indicated with green shading. Criteria
for not selecting the other species are indicated with yellow shading.

In the winter of 2010-2011, an outbreak of highly pathogenic avian influenza virus (HPAIV) infection occurred in wild and domestic birds in Japan. Tufted ducks were found dead in an urban area of Toyota City, Koriyama, Fukushima Prefecture. Two tufted ducks were examined histopathologically, immunohistochemically and molecularly. Gross findings included marked dark-red clotted blood in the pectoral muscles and multifocal hemorrhages on the serous membranes. Microscopically, non-suppurative meningoencephalitis, multifocal to coalescing pancreatic necrosis and severe pulmonary congestion were observed. HPAIV antigen was detected in the malacic areas, neuronal, glial and ependymal cells, pulmonary capillary endothelial cells and epithelium of pulmonary bronchioles, necrotic pancreatic acini and degenerated cardiac myocytes. The HPAIV isolate was genetically classified into clade 2.3.2.1 group A. The broad distribution of virus antigen in brain and pulmonary tissues associated with HPAIV spontaneous infection in tufted ducks might be useful in understanding its pathogenesis in nature.

... We used mallards, a dabbling duck with a wide breeding range, omnivorous food choice and flexibility with respect to habitat choice [29] In Europe, where the species naturally occurs, it is a partially migratory species. Temperate populations are often sedentary, whereas more northerly populations generally migrate in a south-westerly direction [37]. There is, however, a continuous intermixing between populations [36], as males can follow females from the common wintering sites to their breeding area [30]. ...

The ontogeny of continent-wide navigation mechanisms of the individual organism, despite being crucial for the understanding of animal movement and migration, is still poorly understood. Several previous studies, mainly conducted on passerines, indicate that inexperienced, juvenile birds may not generally correct for displacement during fall migration. Waterbirds such as the mallard (Anas platyrhynchos, Linnaeus 1758) are more flexible in their migration behavior than most migratory songbirds, but previous experiments with waterbirds have not yet allowed clear conclusions about their navigation abilities. Here we tested whether immature mallard ducks correct for latitudinal displacement during fall migration within Europe. During two consecutive fall migration periods, we caught immature females on a stopover site in southeast Sweden, and translocated a group of them ca. 1,000 km to southern Germany. We followed the movements of the ducks via satellite GPS-tracking and observed their migration decisions during the fall and consecutive spring migration. The control animals released in Ottenby behaved as expected from banding recoveries: they continued migration during the winter and in spring returned to the population's breeding grounds in the Baltics and Northwest Russia. Contrary to the control animals, the translocated mallards did not continue migration and stayed at Lake Constance. In spring, three types of movement tactics could be observed: 61.5% of the ducks (16 of 26) stayed around Lake Constance, 27% (7 of 26) migrated in a northerly direction towards Sweden and 11.5% of the individuals (3 of 26) headed east for ca. 1,000 km and then north. We suggest that young female mallards flexibly adjust their migration tactics and develop a navigational map that allows them to return to their natal breeding area.

According to IWC January count data, the Wadden Sea is the only site in the Western Palaearctic holding more waterbirds than the GM (Delany et al., 2006). The overall mean counts we have calculated for the 28 year study period do not provide an accurate measure of the current importance of GM for the 12 waterbird species with significant long-term trends. ...

The Guadalquivir Marshes or Doñana wetland complex is the most important wintering site for migratory waterbirds in the Mediterranean region. However, there is a lack of previous information on the status of different species in this area. Using monthly aerial counts conducted from 1978 to 2005, we analysed the size of wintering populations of 21 waterbird species, their distribution within the Guadalquivir Marshes, and their long-term population trends. We used Underhill indices to replace missing values and to correct for flocks of unidentified ducks. Based on long-term means, we identified 16 species whose populations at Doñana exceed 1% of the biogeographical flyway population. For at least 1 month of the year, mean counts were around 10% of the flyway population for six species. The natural, temporary marshes of Doñana National Park were particularly important for Anatidae, ricefields for gulls, white storks and grey herons, fish ponds for flamingos, cormorants and avocets, and salt pans for shelduck. Four Anatidae species have undergone long-term declines and eight non-Anatidae have undergone long-term increases. Population trends were related with trophic guild, migratory status and habitat use. Winter visitors and herbivorous species showed more negative trends than resident, omnivorous–carnivorous species. Those species concentrated in strictly-protected natural marshes have tended to decline. The surface area of ricefields and fish ponds has increased over the study period, and bird species concentrated in these artificial wetlands have tended to increase. This raises questions about the value of waterbirds as flagship or umbrella species for wetland conservation.

This is the 70th annual report of the British Trust for Ornithology's Ringing Scheme, covering work carried out, and data received, in 2006. During the year recoveries of ringed birds were used to assess the possibility of highly pathogenic Avian Influenza H5N1 being spread across Europe and into Britain by wild birds. Recovery reports were vital in understanding this risk and advising government. A study of wader survival using existing data showed that monitoring is possible, but is less effective in sites where there are low encounter rates. Constant Effort Site (CES) data show how widely adult numbers can vary from year to year, with six species showing a significant reversal in trend (with five having fallen) from the previous year. There is particular concern for Bullfinch as adult numbers decreased by 16% in 2006, a continuing downward trend that has seen numbers of the species halve since the 1970s. Five species showed a significant increase in productivity when compared to the previous year, while four showed a significant decrease. Data for 106 Retrapping Adults for Survival (RAS) studies were submitted. The final year of fieldwork for the Swallow Roost Project was completed. Although the total number of birds ringed (853,081) was lower than that in both 2005 and 2004, it was a 1% increase on the mean of the years 2002-05. The recovery total (13,785) was the highest since 1991, and was 16% higher than the mean of the previous five years. Recoveries of 251 individual birds are presented in the report. They include unexpected movements, movements that confirm suspected or known migration patterns, and longevity records.

We use a new method called “product kernel estimator” to explore the spatial and temporal distribution of 9,114 recoveries of Teal (Anas crecca) ringed in Camargue, southern France, and recovered over the whole of Europe. This method allows exploration of the changes in time of the probability density to recover a ringed bird over a grid covering the study area. We thus identified two migration corridors for this species to the north and south of the Alps, whereas earlier analyses mostly suggested a southern route from Camargue, especially in spring. The northern route seems to be used to a greater extent in autumn than in spring, indicating a frequent abmigration (animals switching from one corridor to the other). Moreover, migration of the population seems faster in spring than in autumn. The simultaneous presence of Teal recoveries in many distinct geographical areas in spring is consistent with the idea that these ducks are not limited by their migratory speed in spring, nor do they wait until favorable environmental conditions before colonizing their breeding areas.

Waterbirds are often observed to move between different wintering sites within the same winter—for example, in response to food availability or weather conditions. Within-winter movements may contribute to the spreading of diseases, such as avian influenza, outside the actual migration period. The Common Pochard Aythyaferina seems to be particularly sensitive to infection with the highly pathogenic avian influenza virus H5N1 and, consequently, could play an important role as vectors for the disease. We describe here the within-winter movements of Pochards in Europe in relation to topography, climate, sex and age. We analysed data provided by the Euring data bank on 201 individuals for which records from different locations from the same winter (December–February) were available. The distances and directions moved within the winter varied markedly between regions, which could be ascribed to the differing topography (coast lines, Alps). We found no significant differences in terms of distances and directions moved between the sexes and only weak indications of differences between the age classes. In Switzerland, juveniles moved in more westerly directions than adults. During relatively mild winters, winter harshness had no effect on the distances travelled, but in cold winters, a positive relationship was observed, a pattern possibly triggered by the freezing of lakes. Winter harshness did not influence the directions of the movement. About 41% (83/201) of the Pochards that were recovered at least 1km from the ringing site had moved more than 200km. A substantial number of birds moved between central/southern Europe and the north-western coast of mainland Europe, and between the north-western coast of mainland Europe and Great Britain, whereas no direct exchange between Great Britain and central/southern Europe was observed. Within-winter movements of Pochards seem to be a common phenomenon in all years and possibly occur as a response to the depletion of food resources. This high tendency to move could potentially contribute to the spread of bird-transmitted diseases outside the actual migration period.

The true distribution of migrant species is rarely immediately apparent from the distribution of ring recoveries due to a heavy bias in regional recovery probabilities. For western Palearctic species, the recovery probability is especially low in Africa, but also varies within Europe. However, little work has been done to derive actual estimates of these recovery probabilities needed to infer the “true” underlying distribution. Here, we investigate the potential of using ringing data to estimate the seasonal distribution densities of migrant species. Using likelihoods based on a two point mixture distribution, the proportions of individuals wintering south of the Sahara are estimated using differences in recovery distributions among species in species groups where the location-specific probability of a ring recovery can be assumed to be essentially the same among species. We consider two such approaches. In the first, survival associated with a wintering area must be set constant across species. In the second, we assume the time series is long enough that a single binary response (recovered/not recovered) may be modeled independently of survival parameters. Under the first approach, we estimated the proportion of sub-Saharan migrants, together with 95% profile likelihood confidence intervals, for redstart as 0.84 [0.70,0.93], thrush nightingale 1.00 [0.49,1.00], garden warbler 0.95 [0.85;0.99], blackcap 0.60 [0.32;0.78], reed warbler 0.87 [0.72,0.95], and pied flycatcher 0.90 [0.76;0.97] using recovery data for birds ringed in Denmark and assuming that all robins winter north of Sahara. In the second approach, estimated proportions of sub-Saharan migrants were similar, but the confidence intervals were somewhat narrower. Although further work is required to examine the underlying assumptions, the models and analyses presented here provide a framework for making better use of existing ring recovery datasets to understand the “true” seasonal distribution patterns of European birds.

The outbreak of highly pathogenic avian influenza of the H5N1 subtype in Asia, which has subsequently spread to Russia, the Middle East, Europe, and Africa, has put increased focus on the role of wild birds in the persistence of influenza viruses. The ecology, epidemiology, genetics, and evolution of pathogens cannot be fully understood without taking into account the ecology of their hosts. Here, we review our current knowledge on global patterns of influenza virus infections in wild birds, discuss these patterns in the context of host ecology and in particular birds' behavior, and identify some important gaps in our current knowledge.

In this review we examine the hypothesis that aquatic birds are the primordial source of all influenza viruses in other species and study the ecological features that permit the perpetuation of influenza viruses in aquatic avian species. Phylogenetic analysis of the nucleotide sequence of influenza A virus RNA segments coding for the spike proteins (HA, NA, and M2) and the internal proteins (PB2, PB1, PA, NP, M, and NS) from a wide range of hosts, geographical regions, and influenza A virus subtypes support the following conclusions. (i) Two partly overlapping reservoirs of influenza A viruses exist in migrating waterfowl and shorebirds throughout the world. These species harbor influenza viruses of all the known HA and NA subtypes. (ii) Influenza viruses have evolved into a number of host-specific lineages that are exemplified by the NP gene and include equine Prague/56, recent equine strains, classical swine and human strains, H13 gull strains, and all other avian strains. Other genes show similar patterns, but with extensive evidence of genetic reassortment. Geographical as well as host-specific lineages are evident. (iii) All of the influenza A viruses of mammalian sources originated from the avian gene pool, and it is possible that influenza B viruses also arose from the same source. (iv) The different virus lineages are predominantly host specific, but there are periodic exchanges of influenza virus genes or whole viruses between species, giving rise to pandemics of disease in humans, lower animals, and birds. (v) The influenza viruses currently circulating in humans and pigs in North America originated by transmission of all genes from the avian reservoir prior to the 1918 Spanish influenza pandemic; some of the genes have subsequently been replaced by others from the influenza gene pool in birds. (vi) The influenza virus gene pool in aquatic birds of the world is probably perpetuated by low-level transmission within that species throughout the year. (vii) There is evidence that most new human pandemic strains and variants have originated in southern China. (viii) There is speculation that pigs may serve as the intermediate host in genetic exchange between influenza viruses in avian and humans, but experimental evidence is lacking. (ix) Once the ecological properties of influenza viruses are understood, it may be possible to interdict the introduction of new influenza viruses into humans.
