Abstract
This evaluation is based on a recent compilation on the birds of Guatemala and on workshops with
institutions involved in waterbird conservation. Guatemala has ~250 km of Pacific coast and ~150 km
of Atlantic coast, ~2,780 km
2
of interior water bodies, and 6,270 km
2
of other wetlands as waterbird
habitats, equaling 8.3% of the country. In the country 149 species of waterbirds have been reliably
reported, 29 of them with hypothetical records, without documentation by specimen or photograph.
Three of the 149 species are considered extinct or extirpated: Atitlan Grebe (Podilymbus gigas), Black
Rail (Laterallus jamaicensis), and Eskimo Curlew (Numenius borealis). Reproduction has been
reported for 32 species and is assumed for additional nine species; 103 species are considered non-
reproductive in Guatemala, and the status of five species is uncertain. The Guatemalan region most
species rich in waterbirds is the Pacific Coast, where 123 species have been recorded, followed by
the Pacific Slope (102 species), the Atlantic Coast (88 species), the Atlantic Slope (87 species), and
the Highlands with 47 species. Of the 149 species, 38 are restricted to the Pacific Slope and Coast,
but only 9 species are restricted to the Atlantic Slope and Coast. Based on relative abundance data
from few sites and data on the distribution of wetlands, total populations in Guatemala are estimated
for 91 species. Based on present knowledge, sites on the Pacific coast and slope support the highest
abundances especially of wintering waterbirds. Based on previous evaluations of conservation
priorities on global, regional, and national scales, 54 waterbird species of special concern were
identified. An account of 17 important sites is presented, including status, threats and
recommendations for their conservation.
Introduction
Water is one of the most essential natural resources for mankind. The overall human population on
earth is growing rapidly. Therefore public interest has focused early on the conservation of wetlands.
An international convention on wetlands was signed in 1971 in Ramsar, Iran, providing a framework
for wetland protection. In Guatemala, five sites are designated as Ramsar sites (Valencia Rodríguez
2004; http://www.wetlands.org) and four more are proposed. However, unsustainable land use
practices threaten wetland habitats seriously (e.g. ParksWatch 2005). Mangrove forests have been
evaluated as threatened in all Central America (Dinerstein et al. 1995). Expansion of cattle ranching is
a major threat to fresh water marshes and swamp forests in Guatemala. Introduction of exotic fish
species and overharvest of fish affect the biological balance of water ecosystems. The use of water as
transport medium for waste endangers whole watersheds.
Birds have been identified as adequate organisms for biological monitoring in different kinds of
habitat. While almost all bird species use water at least for drinking and bathing, some are specialized
on habitats near water. In Guatemala approximately 20% of all bird species are waterbirds. Some of
them are specialists of the open sea, others of shaded rainforest rivers, of coastal lagoons and
beaches or freshwater marshes. Knowledge of waterbirds in Guatemala is poor and there is no
national waterbird monitoring as an indicator for habitat quality (Ellison 2004, Eisermann & Avendaño
2006). Habitats are disappearing without the possibility to quantify the loss of biodiversity. This report
is an attempt to quantify waterbird populations in Guatemala and to identify important sites with the
objectives addressed on a global scale by Delany & Scott (2002). Main deficiencies for the
conservation of waterbirds in Guatemala are discussed with the goal to find strategies and solutions
on a regional scale (Kushlan et al. 2002).

Background
The history of documentation of bird species in the area today known as Guatemala reaches back to
the Maya era (2000 BC - 1500 AD); Tozzer & Allen (1910) identified 14 species of birds in Maya
codex figures, including several waterbirds like herons and cormorants. Inventorying waterbird species
with scientific standards began in Guatemala in the 19th century, when major collections of bird
specimens were made. Distributional data from this period were compiled by Salvin & Godman (1879-
1904). Later compilations on species distribution in Guatemala and adjacent areas were published by
Griscom (1932), Dickey & van Rossem (1938), Friedmann et al. (1950), Miller et al. (1957), Russell
(1994), Monroe (1968), Land (1970), Blake (1977), Álvarez del Toro (1980), Thurber et al. (1987),
Miller & Miller (1992), Howell & Webb (1995), Komar (1998), Jones & Vallely (2001), Komar &
Domínguez (2001), Bonta & Anderson (2002), Jones (2003), and Eisermann & Avendaño (2006).
Compilations for North American species, wintering or transient in Guatemala, were published by
Poole & Gill (1992-2003). The compilations are based on the following original works about
waterbirds. The ecology and extinction of the Atitlan Grebe (Podilymbus gigas) has been documented
by Bowes (1964), LaBastille (1969, 1974, 1978, 1983a,b, 1984, 1990a,b, 1992, 1994, 1996), Polunin
(1969), LaBastille & Bowes (1962), Hamilton (1970), LaBastille et al. (1973), Hunter (1988), Prytherch
& Everett (1988), and Wahlstedt (1988). Off-shore birds are the least studied in Guatemala
(Eisermann & Avendaño 2006), with only a few papers focused on them (Salvin 1864, 1865, Jehl
1974, Pitman 1986, Pitman & Jehl 1998, Spear et al. 1995, Huyvaert & Anderson 2004). Band
recoveries of waterbirds in Guatemala have been published for several species (Cooke 1938a,b,
1940, 1946a,b, 1950, Bergstrom 1951, Austin 1953, Chapman 1969, Hopkins 1972, Thurber & Villeda
1972, Gill & Mewaldt 1983, Anonym 1986, Dunning 1987, Botero & Rusch 1988, Schreiber & Mock
1988, Belant & Dolbeer 1993, Houston 2000, King & Greve 2001). The distribution of Cattle Egret
(Bubulcus ibis) in Guatemala, a species of African origin, has been documented by Smithy & Land
(1960) and Crosby (1972). Distributional and natural history data for waterbirds were published by
Salvin (1861, 1864, 1865), Oberholser (1918), Dickey (1929), Deignan (1933), Wetmore (1941, 1945),
Conover (1945), Saunders (1950), Tashian, (1953), Smithe & Paynter (1963), Coues (1964), Weller
(1964), Smithe (1966), Dickerman (1968, 1972, 1973, 1977), Biderman & Dickerman (1978), Jehl
(1979), Zedekar et al. (1980), Wendelken & Martin (1986, 1989), Myers et al. (1990), Beavers et al.
(1991), Beavers (1992), Howell & Webb (1992), Weber & Bucklin (1995), Palacios & Mellink (1996),
Baker et al. (1999), Pérez & Castillo (2000), Eisermann (2003a), Komar (2003), Eisermann &
Avendaño (2004), Herrera (2005), and Herrera & Ibarra (2005). Recent distributional data are
published in quarterly reports on bird records in Central America compiled by Jones (since 2000).
Rapid assessments with information about waterbirds were carried out in the Punta de
Manabique Wildlife Refuge (CECON-CDC 1992, Pérez 1999), in the Laguna del Tigre National Park
(Pérez & Castillo 2000), and Bocas del Polochic Wildlife Refuge (Arrivillaga et al. 1992, Dowell et al.
1994, Holtropp 1995). University studies ("licenciatura" thesis research, university practice) including
waterbirds were carried out at lake Atitlán (Cazali 1984), Bocas del Polochic Wildlife Refuge (Cardona
1994), Manchón-Guamuchal (Sigüenza 1995), Laguna del Tigre National Park (Baumgarten 1998,
Ordoñez 1998, Castillo 1999), Punta de Manabique Wildlife Refuge (Tenez 2001), Laguna Lachuá
National Park (Avendaño 1999, 2001) and Lake Amatitlán (Chávez 1997, 2001). More detailed studies
were carried out in the Bocas del Polochic Wildlife Refuge (Seglund & Conner 1997), in the Punta de
Manabique Wildlife Refuge (Eisermann 2001a, 2003a), and on Lake Güija (Herrera & Ibarra 2005).
Continued monitoring efforts have been made in the Bocas del Polochic Wildlife Refuge (Valle 2002,
Pérez et al. 2003, García 2004, García de la Vega 2005). Dix & Fernández (2001) published an
inventory of 191 Guatemalan wetlands with scarce information on the biological diversity of each site.

Methodology
Definition of terms: This report treats as waterbirds all species of the following bird families with
species distributed in the Neotropics: Spheniscidae, Gaviidae, Podicipedidae, Diomedeidae,
Procellariidae, Hydrobatidae, Pelecanoididae, Phaethontidae, Pelecanidae, Sulidae,
Phalacrocoracidae, Anhingidae, Fregatidae, Ardeidae, Chionididae, Threskiornithidae,
Phoenicopteridae, Anhimidae, Anatidae, Gruidae, Aramidae, Rallidae, Heliornithidae, Eurypygidae,
Jacanidae, Rostratulidae, Haematopodidae, Recurvirostridae, Burhinidae, Charadriidae,
Scolopacidae, Thinocoridae, Ciconiidae, Laridae, Rhynchopidae, and Alcidae.
The term "wetland" is used for all kinds of waterbird habitats: off-shore, beaches, estuaries and
river mouths, salt and fresh water marshes, swamp forests, mangroves, lakes, and rivers.
Sources of information: I reviewed relevant literature including gray literature, recently compiled in a
bibliographic list by Eisermann & Avendaño (2006). Unwritten information was gathered during two
workshops with relevant institutions. One workshop was held on 7 September 2005 in Flores, Petén,
with institutions active in northern Guatemala (Petén) and a second workshop was held on 12
September 2005 in Guatemala City with institutions active in southern Guatemala. See section "13.
References/experts consulted" for the names of participating institutions and personnel.
Spatial analysis are based on GIS layers which have been prepared with Landsat satellite
images and topographic maps 1:250,000 (MAGA 2002).
For some of the key sites a satellite image (Landsat SWIR bands, provided online by NASA at
https://zulu.ssc.nasa.gov/mrsid) is presented, which illustrates the distributions of forest and water
bodies. Images are from the year 2000.
Distribution: A division of geographical units is used for the description of species distribution (Fig.
1): Atlantic Slope and Pacific Slope (<900 masl), Highlands (>900 masl), Atlantic Coast and Pacific
Coast (coastal waters, beaches, estuaries and mangrove).
Population estimates and status: No population census
data were available for Guatemalan wetlands. Data on
relative abundance were available for some sites. From
these I estimated population sizes for the sites. For the
whole area of suitable habitat (derived from MAGA 2002), I
applied the mean population size per km
2
of wetland from
sites with relative abundance data. The median was taken
of a range of values of abundance from expert opinions for
further estimates. Similar to classes applied by Delany &
Scott (2002) for the size of world populations, I present
estimates for the populations in Guatemala as best-guess
information in the following classes: A <50 individuals; B
51-250; C 251-1,000; D 1,001-10,000; E 10,000-50,000; F
>50,000. The estimated percentage of the total population
of the subspecies or regional population was calculated
based on the most recent numbers given by Delany & Scott (2002). I assume that all individuals of
populations entirely breeding in North America and entirely wintering in South America, pass through
Guatemala. The percentage of the regional population is therfore marked with "100%".
In-country population trends are based on expert opinions collected during workshops,
however no long-term monitoring data were available. I used categories proposed by Delany & Scott
(2002): Stable, Decreasing, Increasing, Fluctuating, Extinct, and I added Data Deficient as an
additional category.

Identification of important sites and species of special concern: I define an important site as a
land unit which can be managed for conservation (usually a protected area, a part of a river, a lake or
small scale watershed, or other naturally defined wetland) with relatively high species richness and/or
high abundances, or with records of species of special concern. Species of special concern are
globally threatened species (BirdLife International 2004), species listed in Parker et al. (1996) with
conservation priority in the Neotropics, species with populations at risk or at potential risk in North and
Central America (Kushlan et al. 2002), or species listed as threatened in Guatemala (Eisermann &
Avendaño 2006).
Species nomenclature follows AOU (1998) and supplements; names of species treated in this report
are influenced by Banks et al. (2000, 2002). Common local names are given for some regions of
Guatemala. Local Spanish names were provided by Eisermann (2001a) for the Punta de Manabique
Wildlife Refuge, Izabal, and for Petén, names were compiled during the workshop. Names in the
Q'eqchi' language for some species or groups of species were provided by the bird census takers
from the community Rocjá Pomtilá, Cobán, Alta Verapaz (PROEVAL RAXMU Bird Monitoring
Program, Eisermann 2003b). However, the account of local names remains incomplete, considering
that 24 languages are spoken in Guatemala (Secaira 2000).
Results
Species occurring within the country
In Guatemala 149 waterbird species of 24 families (Fig. 2) have been reliably reported (Appendix I,
see Appendix II for common names), 29 species of them with hypothetical records lacking a
documentation by specimen or photograph (Eisermann & Avendaño 2006). Table 1 summarizes
status of residency of waterbird species, see Appendix I for the category of each species. An
additional 19 species may occur in Guatemala; they have been recorded near Guatemala in
neighbouring countries (Appendix III).
Of the 149 species of waterbirds, most species occur in Guatemala exclusively as visitors (Fig.
2). Reproduction is documented for 32 species, an additional 9 species are assumed to nest in
Guatemala, 103 species are considered non-reproductive in Guatemala, and the status of five species
is uncertain.

number of species recorded. Non-reproductive visitors include vagrants and transients.
One species, the Atitlan Grebe (Podilymbus gigas), was restricted to the Atitlán Lake and is now
considered extinct (Wege & Long 1995, O’Donnel & Fjeldså 1997, Hilton-Taylor 2000, BirdLife
International 2004). There exist apparently no recent record of Black Rail (Laterallus jamaicensis)
(Howell & Webb 1995), and the Eskimo Curlew (Numenius borealis) was recorded reliably only once
in Guatemala (Salvin 1861). Both species are considered locally extirpated (Eisermann & Avendaño
2006).

Distribution and habitat needs information
Guatemala covers an area of ~108,900 km
2
, with ~250 km Pacific coast line and ~150 km Atlantic
coast line. All types of wetlands (without coastal waters) cover a total of 9,043 km
2
, which is 8.3% of
Guatemala (Fig. 3). Of this total wetland area, the interior water bodies including major rivers cover
~2,779 km
2
, equaling ~2.5% of the country. Forested wetlands including mangroves and other
wetlands cover ~6,264 km2, equaling ~5.8% of the country. Guatemala has no oceanic islands, which
are important nesting sites for seabirds in other Central American countries (e.g. Angehr 2003).
Guatemala's region with the highest species richness in waterbirds is the Pacific Coast, where
123 species have been recorded, followed by the Pacific Slope (102 species), the Atlantic Coast (88
species), the Atlantic Slope (87 species), and the Highlands with 47 species (Appendix I). Of the 149
species, 38 are restricted to the Pacific Slope and Coast, but only 9 species are restricted to the
Atlantic Slope and Coast.
A total of 33 species are
restricted to one of the five
regions (Appendix I). Nineteen
species occur exclusively on
the Pacific Coast: Parkinson’s
Petrel (Procellaria parkinsoni),
Pink-footed Shearwater
(Puffinus creatopus), Wedge-
tailed Shearwater (Puffinus
pacificus), Sooty Shearwater
(Puffinus griseus), Christmas
Shearwater (Puffinus
nativitatis), Audubon’s
Shearwater (Puffinus
lherminieri), Wilson’s Storm-
Petrel (Oceanites oceanicus),
Leach’s Storm-Petrel
(Oceanodroma leucorhoa),
Wedge-rumped Storm-Petrel
(Oceanodroma tethys), Black
Storm-Petrel (Oceanodroma
melania), Least Storm-Petrel
(Oceanodroma microsoma),
Red-billed Tropicbird
(Phaethon aethereus), Nazca
Booby (Sula granti), South
Polar Skua (Stercorarius
maccormicki), Long-tailed
Jaeger (Stercorarius
longicaudus), Heermann’s Gull (Larus heermanni), Sabine’s Gull (Xema sabini), Elegant Tern (Sterna
elegans), and Arctic Tern (Sterna paradisaea). Four species occur exclusively on the Atlantic Coast:
White-tailed Tropicbird (Phaethon lepturus), Double-crested Cormorant (Phalacrocorax auritus),
Roseate Tern (Sterna dougallii), and Bridled Tern (Sterna anaethetus); two exclusively on the Atlantic
Slope: Pinnated Bittern (Botaurus pinnatus) and Sunbittern (Eurypyga helias); one on the Pacific slope
(Mallard Anas platyrhynchos), and seven species have been recorded exclusively in the Highlands:
Canvasback (Aythya valisineria), Eared Grebe (Podiceps nigricollis), Virginia Rail (Rallus limicola),
Wilson’s Phalarope (Phalaropus tricolor), the extinct Atitlan Grebe (Podilymbus gigas), the extirpated
Black Rail (Laterallus jamaicensis), and Eskimo Curlew (Numenius borealis). Distribution maps of

Population estimates, percent of global population, and in-country trends (status)
The estimation is based on relative abundance data from four sites on the Atlantic slope, four sites on
the Pacific slope, and two sites in the Highlands (Table 2). Details for the derivation of population
estimates are given in Appendix V. The following species are breeding in North America and wintering
in South America (Howell & Webb 1995); I assume that all individuals pass through Guatemala:
American Golden-Plover (Pluvialis dominica), Upland Sandpiper (Bartramia longicauda), Hudsonian
Godwit (Limosa haemastica), Buff-breasted Sandpiper (Tryngites subruficollis), and Franklin's Gull
(Larus pipixcan). With exception of Franklin's Gull, there are only few records of all of these species in
Guatemala. Migration happens probably mainly at night, as a report of 30 hunted Upland Sandpipers
in one night in a village in Huehuetanago suggests (Baepler 1962). The overall waterbird population in
Guatemala is estimated to be ~1.8 million individuals.
Noteworthy is the population estimate of 1960 individuals of the Bare-throated Tiger-Heron
(Tigrisoma mexicanum), which represents almost 20% of the estimated world population (Delany &
Scott 2002, Kushlan et al. 2002). Eleven more species are supposed to have >1% of the regional
population in Guatemala: Fulvous Whistling-Duck (Dendrocygna bicolor), Blue-winged Teal (Anas
discors), Least Grebe (Tachybaptus dominicus), American White Pelican (Pelecanus
erythrorhynchos), Little Blue Heron (Egretta caerulea), Cattle Egret (Bubulcus ibis), Jabiru (Jabiru
mycteria), Wood Storck (Mycteria americana), American Coot (Fulica americana), Collared Plover
(Charadrius collaris), Spotted Sandpiper (Actitis macularius). However, all estimates are preliminary
due to the lack of useful field data. None of the key sites in Guatemala supports 1% of the regional
population.

For 56 of the 149 waterbird species in Guatemala, data were deficient and I was unable to estimate
the population. National population estimates, percentage of global populations, and overall in-country
trend are listed in Appendix I. For the lack of data trends could be estimated for only 31 species. I
assume a population decrease for all species which prefer wooded wetlands due to habitat alteration
(Fig. 22), like Boat-billed (Cochlearius cochlearius) or Agami Heron (Agamia agami).
Species of Special Concern
A total of 54 species of special concern have been identified (Table 3). Four species are included in
the Red List of globally threatened bird species (BirdLife International 2004, IUCN
http://www.redlist.org), nine species have been evaluated with medium to urgent conservation priority
in the Neotropics (Parker et al. 1996), and 19 species have been evaluated at risk or potential risk in
North and Central America (Kushlan et al. 2002). In the official national Red List (CONAP 2001) many
waterbird families were ignored, but 37 species have been evaluated as threatened or data deficient
on a national scale by Eisermann & Avendaño (2006).

borealis) is listed as Critically Endangered, in Guatemala it has been recorded reliably only once
(Salvin 1861). Vulnerable are Parkinson's Petrel (Procellaria parkinsoni) and Pink-footed Shearwater
(Puffinus creatopus). Seabirds have been identified as the least investigated group of birds in
Guatemala (Eisermann & Avendaño 2006). P. parkinsoni breeds on two islands in New Zealand.
During migration to the Pacific waters off Mesoamerica and South America the species is threatened
by fisheries (BirdLife International 2004). P. creatopus breeds exclusively on islands off Chile (Collar
et al. 1992). The species has been reported entangled in fishing gear (BirdLife International 2004).
Abundances and the impact of fisheries on both species in Guatemala is unknown. Regular
monitoring of populations off Central America should be undertaken, including quantifying the impact
of fisheries.
Locations and descriptions of key sites used by aquatic species
A total of 17 important waterbird sites were identified in Guatemala (Fig. 5, Table 4), based on
publications, gray literature, and expert opinions. These include 13 wetlands within protected areas
(including all Guatemalan Ramsar sites) and four wetlands which are not declared as protected areas.
The regional distribution is as follows: four of the key sites are located on the Pacific Coast, one on the
Pacific Slope, two on the Atlantic Coast, eight on the Atlantic Slope and two in the Highlands (Fig. 5).
Based on present knowledge, the sites on the Pacific coast (Manchón-Guamuchal, Sipacate-Naranjo,
Monterrico-Hawaii, and El Paraíso-La Barrona) and Lake Güija support the highest abundances of
waterbirds in Guatemala, especially migratory populations. Sites on the Atlantic coast and slope are
important for their high species richness of waterbirds and for supporting species of special concern.
An account follows of all key sites including information on location, size, habitats,
conservation status, importance, threats, recommendations for conservation improvements, and
involved institutions. Information on the size of protected areas is based on CONAP (2005). See
section "Organizations relevant to waterbird and/or wetland conservation" for full names of
abbreviations of institutions.

Manchón-Guamuchal
• Location: departments Retalhuleu and San Marcos, UTM Zone 15 599800/1597000.
• Size: ~14,900 ha, the Private Protected Area "La Chorrera-Manchón-Guamuchal" covers 1,243 ha
of it (CONAP 2005).
• Habitats: mangrove, reed swamp, beach.
• Conservation status: Private Protected Area; Ramsar site (designated 1995).
• Importance: The site supports large breeding colonies of several heron species (R. Sigüenza) and
large numbers (possibly thousands) of wintering and staging populations of migratory species. No
detailed abundance data are available. At least 23 species of special concern have been recorded
(Appendix IV).
• Threats: Estimated waterbird habitat is ~14,900 ha, most of it designated as Ramsar site (López et
al. 1993; Fig. 6), but 92% of the Ramsar site is unprotected. The area lacks management due to
scarce interaction with private landowners. Hunting seems to be intensive; massive kills of White
Ibis (Eudocimus albus) have been observed (R. Sigüenza, pers. comm.). Sport hunters enter the
area. Deforestation of mangrove and water pollution by agrochemicals were reported by López et
al. (1993) and Schaeffer Novelli (2003). There is insufficient surveillance in the area.
• Recommendations for conservation improvement: Promote communication with all landowners
within the Ramsar site and apply a management plan for the Ramsar site.
• Involved Institutions: INAB, CONAP, OCRET.
Fig. 6. Area of Manchón-Guamuchal; approximate border of Ramsar site is marked by the yellow line, the approximate
border of the Private Reserve is marked by the red line. The dark green area along the coast line is mangrove, which is
bordered by reed swamps and agricultural land (light green areas, areas with shades of magenta, lavender and pink).

Sipacate-Naranjo
• Location: department Escuintla, UTM Zone 15 711000 / 1541000.
• Size: ~3,300 ha, the National Park covers 2,000 ha of it.
• Habitats: mangrove, reed swamp, beach.
• Conservation status: National Park.
• Importance: Large nesting colony of herons (apparently Ardea alba, according to description by F.
Valenzuela). At least 13 species of special concern have been recorded (Appendix IV).
• Threats: Estimated waterbird habitat is ~3,300 ha, therefore ~1,300 ha are unprotected (Fig. 7).
Massive harvest of heron chicks in the nesting colonies; the meat is sold at markets in Guatemala
City (R. Sigüenza, pers. comm.). Sewage from the sugar industry is causing yearly dying of fish
between May and November (F. Valenzuela, pers. comm.). The area is used by sport hunters and
there is insufficient institutional control. Mangrove is deforested by local people.
• Recommendations for conservation improvement: The first management master plan has been
elaborated for the period 2002-2006 (CONAP 2002). To prevent harvest on nesting sites,
surveillance needs to be improved, which requires additional personnel.
• Involved Institutions: CONAP, OCRET.
Fig. 7. Area of Sipacate-Naranjo; approximate border of the National Park is marked by the yellow line. The dark green area
along the coast line is mangrove, which is bordered by agricultural land (light green areas, areas with shades of magenta,

Monterrico - Hawaii
• Location: department Santa Rosa, UTM Zone 15 777000 / 1537000
• Size: Monterrico 2,800 ha; Hawaii 3,657 ha (ARCAS 2004)
• Habitats: reed swamp, mangrove, beach.
• Conservation status: Monterrico is an Area of Multiple Use, Hawaii is an proposed Area of Multiple
Use (Fig. 8). The largest lagoons north of Monterrico have not been included in the protected area.
• Importance: Monterrico-Hawaii is the second-largest mangrove area in Guatemala, after
Manchón-Guamuchal. A high abundance of wintering waterbirds has been found, especially in
shallow lagoons within reed swamp: 500 Pelecanus erythrorhynchos (Eisermann in Jones 2005b),
>1,000 Ardea alba, >200 Egretta thula, >100 Butorides virescens, >50 Mycteria americana, >300
Anas discors (pers. obs.). At least 21 species of special concern have been recorded (Appendix
IV).
• Threats: Subsistence fisheries and shrimp larva harvest (Sigüenza de Micheo & Ruiz Ordoñez
2000), burning reed for the harvest of a snail, mangrove deforestation as fuel for salt production
and firewood.
• Recommendations for conservation improvement: A declaration as Ramsar site might be
considered. Monterrico and neighbouring beaches are popular national and international tourist
destinations. Approximately 9,000 people live within the protected areas of Monterrico-Hawaii
(Sigüenza de Micheo & Ruiz Ordoñez 2000, ARCAS 2004), further development of tourism
services may provide more people with alternative income.
• Involved Institutions: CECON (administration in Monterrico), ARCAS (administration in Hawaii),
OCRET.

El Paraíso - La Barrona
• Location: department Jutiapa, UTM Zone 15 803000 / 1525000.
• Size: ~2,700 ha.
• Habitats: mangrove, beach.
• Conservation status: The area has been proposed as protected area and also as Ramsar site (F.
Castro, pers. comm.).
• Importance: Congregations of waterbirds have been observed (R. Sigüenza, pers. comm.) but no
data or report is available. I assume similarities of the bird community with Monterrico- Hawaii due
to the proximity and similar habitat.
• Threats: Deforestation of mangrove for firewood. American White Pelicans (Pelecanus
erythrorhynchos) are killed on shrimp farms (R. Sigüenza, pers. comm.)
• Recommendations for conservation improvement: Apply a management plan.
• Involved Institutions: OCRET, CONAP, INAB.

Lake Güija
• Location: department Jutiapa, UTM Zone 16 224000 / 1579000, and Santa Ana, El Salvador.
• Size: 4,200 ha, of which 1,010 ha are on Guatemalan territory.
• Habitats: Lake, reeds.
• Conservation status: The area has been proposed as protected area and also as Ramsar site
(MARN 2001, F. Castro, pers. comm.).
• Importance: Wintering site for several thousands of Nearctic-Neotropical migratory waterbirds
(Herrera & Ibarra 2005, Herrera, pers. comm.), e.g. 11,150 Fulica americana; 10,000 Anas
discors; 5,100 Dendrocygna bicolor; 3,500 Aythya affinis; 2,000 Dendrocygna autumnalis; 1,200
Anas clypeata; 630 Sterna caspia; and 300 Mycteria americana. At least 19 species of special
concern have been recorded (Appendix IV).
• Threats: Eutrophycation by surrounding agricultural activities and settlements. Fisheries seem to
be intensive (MARN 2001), but I am unable to assess the impact on waterbird populations due to
a lack of data.
• Recommendations for conservation improvement: Apply a management plan.
• Involved Institutions: CONAP, A3K.

Lake Amatitlán
• Location: department Guatemala, UTM Zone 15 762000 / 1600000.
• Size: 1,520 ha.
• Habitat: Lake.
• Conservation status: not declared as protected area.
• Importance: Wintering and stopover site for Nearctic-Neotropical migratory waterbirds: 100 Anas
acuta, 40 Anas discors, 20 Anas clypeata, 20 Aythya affinis, 1,500 Fulica americana (Chávez
2001). At least 10 species of special concern have been recorded (Appendix IV).
• Threats: A dense human population and industrial and domestic sewage input from Guatemala
City (via Villalobos River) causes water pollution and lake degradation by major sedimentation
(Fig. 11). The watershed of Lake Amatitlán has been identified as the most polluted Guatemalan
region (AMSA 1998, CEPAL 2002). High degree of deforestation around the lake. Eutrophycation
causes expansion of water hyacinth Eichhornia crassipes.
• Recommendations for conservation improvement: A governmental project including a waste water
purification plant is on the way. According to Martínez (2005) the first plant is working since 2005.
Water quality should be continously monitored.
• Involved Institutions: FUNDALAGO, Comité del Lago de Amatitlán, AMSA.

Lake Atitlán
• Location: department Sololá, UTM Zone 15 693000 / 1626000
• Size: 12,700 ha
• Habitat: Lake.
• Conservation status: Area of Multiple Use
• Importance: Former site of the endemic Atitlan Grebe (Podilymbus gigas), which is considered
extinct (BirdLife International 2004). Presumed nesting site of Ruddy Duck (Oxyura jamaicensis).
Wintering and stopover site for water fowl. At least 5 species of special concern have been
recorded recently (Appendix IV).
• Threats: Loss of reed habitat along the shore due to a continuously dropping water level has been
observed since a major earthquake in 1976 and has been evaluated as one of the reasons for the
extinction of the Atitlan Grebe (Hunter 1988, LaBastille 1992). Introduction of exotic fish species,
mainly Micropterus salmoides, caused reduction of food resources for waterbirds (LaBastille 1974,
1984). Eutrophycation through input of sewage from communities along the shore has increased
in the last decades (Castellanos et al. 2002, Dix et al. 2003). Reed (Typha domingensisi, Scirpus
californicus) is overharvested for handicrafts, which reduces nesting sites.
• Recommendations for conservation improvement: The installation of sewage treatment in all
communities and enterprises (mainly hotels) around the lake should be fulfilled in the short term.
Harvest of reed should be managed, during breeding season it should be avoided.
• Involved Institutions: CONAP, TNC, AMSCLAE, Asociación Patronato Vivamos Mejor.

Punta de Manabique
• Location: department Izabal, UTM Zone 16 344000 / 1752000.
• Size: 66,900 ha terrestrial; 66,000 ha coastal waters (Fig. 14).
• Habitats: Swamp forest, mangrove, salt marshes, beach, coastal waters.
• Conservation status: Wildlife Refuge; Ramsar site (designated 2000).
• Importance: High species richness of waterbirds, although no species has been found in high
abundances; 25 species of shorebirds; nesting colony of 40 pairs of Ardea alba; 29 species of
special concern have been recorded (Appendix IV).
• Threats: Habitat alteration (deforestation for cattle farming) mainly in the southern part of the
reserve (Fig. 13; Sigüenza 1999) cause an increase of water pollution with agrochemicals. The
Motagua river, crossing Guatemala from the western highlands to the Gulf of Honduras, has
impact over coastal waters with a high load of industrial sewage and agrochemicals. Occasional
dying of fish has been observed on the lower Motagua river (Grupo Seguridad y Justicia 2003).
Unsustainable subsistence fishery methods cause reduction of food resources: anchovies
(Anchoa sp.) are harvested along the coast with small-mesh nets, and mouths of estuaries and
rivers are crossed with nets in order to harvest fish populations moving between the sea and the
inland water bodies. Institutional control in the area is weakened by lawlessness (Eisermann
2003c,d; CALAS 2005a).
• Recommendations for conservation improvement: Surveillance in the areas needs to be reinforced
to prevent overharvest of natural resources, coupled with the development of alternative income.
• Involved Institutions: CONAP, FUNDARY.

Río Dulce / Chocón Machacas / Río Sarstún
• Location: department Izabal, UTM Zone 16, 301000 / 1744000 (Fig. 14)
• Size: total 54,457 ha (Río Dulce 13,000 ha; Chocón-Machacas 6,265 ha; Río Sarstún 35,202 ha).
• Habitats: river, lake, mangrove (Yañez-Arancibia et al. 1994).
• Conservation Status: Río Dulce (National Park); Chocón Machacas (Biotope); Río Sarstún (Area
of Multiple Use).
• Importance: In the area 16 species of special concern have been recorded (Appendix IV).
• Threats: Deforestation for agriculture (cattle farming) causes habitat loss and water pollution.
Several settlements are located within the area, the use of natural resources is unsustainable. The
Biotope Chocón-Machacas has been evaluated as critically threatened (ParksWatch 2003a).
• Recommendations for conservation improvement: Surveillance should be reinforced and
management plans applied.
• Involved Institutions: CONAP, FUNDAECO, CECON.

Bocas del Polochic
• Location: department Izabal, UTM Zone 16, 242000 / 1709000 (Fig. 14).
• Size: 20,760 ha.
• Habitats: freshwater swamp (wooded and reed), river.
• Conservation status: Wildlife Refuge; Ramsar site (designated 1996).
• Importance: High species richness, 20 species of special concern have been recorded (Appendix
IV).
• Threats: The reserve is surrounded by private farm land (rice and cattle farming). Pollution with
agrochemical is presumed. Fish is overharvested by local people, causing reduction of food
resources. Nickel mining north of the reserve is proposed and may in future cause pollution with
heavy metals. Sport hunting has been observed (G. Martínez, pers. comm.), but not quantified.
• Recommendations for conservation improvement: Monitoring of heavy metal pollution should be
installed. Reinforcement of surveillance of use of natural resources.
• Involved Institutions: CONAP, FDN, AMAZURLY.

Laguna Lachuá and Floodplain of the Ik'bolay river
• Location: department Alta Verapaz, UTM Zone 15, 755000 / 1752000.
• Size: ~19,550 ha.
• Habitats: Lake, wooded rivers, yearly flooded woodlands.
• Conservation status: National Park (partially), see Fig. 15.
• Importance: High species richness, 13 species of special concern have been recorded (Appendix
IV).
• Threats: Local people around the National Park live mainly from growing corn for subsistence and
cardamom as cash crops. Large farms for cattle ranching have been founded in the last years
which cause considerable landscape pauperization, which is a major threat especially for the
floodplain, which is unprotected.
• Recommendations for conservation improvement: Extend the technical assistance to develop
alternative crops like cacao and vanilla with the local population.
• Involved Institutions: INAB, IUCN, Sank', PROEVAL RAXMU, USAC.

• Size: 116,991ha.
• Habitats: Swamp forest and freshwater marshes, rivers.
• Conservation status: National Park, part of the Maya Biosphere Reserve.
• Importance: Extensive swamps within the largest continuous tropical forest in Central America. At
least 12 species of special concern have been recorded (Appendix IV).
• Threats: Habitat alteration is an issue in the whole Maya Biosphere Reserve. Although the
Mirador-Río Azul National Park belongs currently to the most pristine areas, near future threats
may be caused by proposed road constructions between Petén and México and the development
of tourism infrastructure in these areas (ParksWatch 2002b).

Laguna del Tigre
• Location: department Petén, UTM Zone 15, 750000 / 1940000.
• Size: 335,080 ha.
• Habitats: Rivers, lagoons, freshwater marshes, swamp forest.
• Conservation status: National Park, Biotope; both reserves are part of the Maya Biosphere
Reserve (Fig. 20); Ramsar site (designated 1990).
• Importance: The northwestern part of Petén is the largest wetland area in Guatemala. At least 22
species of special concern have been recorded (Appendix IV) and reproduction has been
confirmed for Himantopus mexicanus (R. Balas McNab, pers. comm.).
• Threats: Laguna del Tigre has been evaluated as critically threatened (ParksWatch 2003b,c). Both
documents summarize the threats which include forest fires, illegal settlements, agriculture (mainly
cattle farming), oil exploitation, and illegal extraction of natural resources. The issues are
worsened by lack of institutional control and general lawlessness. Reports are available online at
www.parkswatch.org. To date all threats have continued and worsened; in fact ~50% of this
protected area is damaged (ParksWatch 2005).
• Recommendations for conservation improvement: A special law has been created in 2004 for the
rescue of this National Park (Decreto 16-04, see section "Legislation"). Urgent action is required to
save at least 50% of the area (ParksWatch 2005).
• Involved Institutions: CONAP, CECON, IDAEH, WCS, ProPetén, SEPRONA, Ejército Nacional de
Guatemala, ProPetén.

• Lake Izabal (unprotected area), Izabal: Largest lake
in Guatemala, except for the Bocas del Polochic
Wildlife Refuge, no data exist about the use by
waterbirds. ~68,000 ha; UTM Zone 16 270000 /
1716000.
• Castañeda Salguero (1995) compiled an inventory of
1,139 lagoons at sizes <1,000 ha in Guatemala (Fig.
21). Many of them are included in important sites for
waterbirds, e.g. Laguna del Tigre, Punta de
Manabique, Bocas del Polochic and Manchón-
Guamuchal, but the status and importance of many
other lagoons is uncertain.
Issues and threats to waterbirds and their habitats
The human population in Guatemala is growing rapidly, an increase of 35% has been documented
from 1994-2002 (INE 2002). The national economy depends basically on small and medium scale
agriculture and a major part of the human population are subsistence farmers. Increasing land
requirements for agriculture cause pressure also on waterbird habitats.
Main threats to waterbird populations in Guatemala include the following:
• Lack of knowledge about waterbird populations
• Habitat alteration
• Reduction of food resources
• Hunting and fisheries
• Introduced species
• Water pollution
• Disturbance on roosting and foraging sites
• Management deficiencies
• General lack of environmental consciousness in the Guatemalan society
Lack of knowledge of waterbird populations
There is a lack of published data on the recent distribution of waterbirds in Guatemala (Ellison 2004,
Eisermann & Avendaño 2006); this report is based almost exclusively on unpublished reports and
expert opinions. Unpublished information was very limited, due to the lack of monitoring programs or
the inappropriate performance of waterbird monitoring. The least studied group are off shore seabirds.

Waterbird Conservation for the Americas Country Report for Guatemala
32
Habitat alteration
The annual deforestation rate in Guatemala
from 1990-2000 was 1.7%, equaling 485 km
2
(FAO 2003). Today the lowlands on the
Guatemalan Pacific slope are almost entirely
deforested (Fig. 22). Especially waterbirds
requiring wooded habitats, like Agami Heron
(Agamia agami), Boat-billed Heron (Cochlearius
cochlearius), Yellow-crowned Night-Heron
(Nyctanassa violocea), and Sungrebe (Heliornis
fulica) are threatened by the deforestation of
mangroves and swamp forests. All of these
species are resident. Deforestation is a threat in
all parts of Guatemala. A secondary effect of
deforestation is the alteration of water quality.
Another type of habitat alteration is the
harvest of emergent water plants like Scirpus
spp., Typhus spp. (Lake Atitlán, Monterrico),
which affects nesting and foraging habitats of
herons and rails.
Eutrophycation through water pollution
may alter habitat by massive growth of floating
plants, like Eichhornia crassipes, which can
cover small water bodies completely.
Water bodies were directly altered
through the construction of dams for electric power production, the largest one across the Chixoy
river. Human modification of river beds and banks has not been an issue in Guatemala, but after a
recent storm disaster along the Pacific Slope in October 2005 (Hurricane STAN), a national fond was
created for constructing artifical river beds (González Arrecis 2005).
Reduction of food resources
Waterbirds feed mainly on fish, arthropods and their larvae, small vertebrates, plankton, and plants
(Poole & Gill 1992-2003). Fish and crustaceans are reduced directly by human competition. Fish is
harvested in all water bodies near human settlements. Comments by local people explaining that
quantity and quality (size) decreased drastically are indicators of overharvest. This is a major problem
in regions where local people live mainly from fisheries (coastal regions, e.g. Punta de Manabique,
Monterrico-Hawaii). Indirect reduction of food resources (major fish dyings) through water pollution
has been reported in Sipacate-Naranjo and on the Motagua river (Punta de Manabique).
Hunting and fisheries
Subsistence hunting is common in rural communities in Guatemala, but waterbirds are not the main
target, with exception of Muscovy Duck (Cairina moschata) and migratory ducks. In Sipacate-Naranjo
heron chicks (Ardea alba) have been harvested at a nesting colony and in Manchón-Guamuchal
hunting of White Ibis (Eudocimus albus) has been observed. In the department Huehuetenango
migratory birds are hunted at night using fires, the method is locally known as "chitbal" (Monzón
1976). Baepler (1962) reported that in one night 30 Upland Sandpipers (Batramia longicauda) were
taken by the local people.

Waterbird Conservation for the Americas Country Report for Guatemala
33
Sport hunting has been observed in Bocas del Polochic, Sipacate-Naranjo, Manchón-
Guamuchal, but the impact on waterbird populations can not be assessed due to the lack of
quantifying data. On agricultural cultivations (rice fields) or fish and shrimp farms, where certain
waterbirds are thought to cause economic loss, shooting these birds is common (e.g. Black-bellied
Whistling Duck Dendrocygna autumnalis, Muscovy Duck Cairina moschata, American White Pelican
Pelecanus erythrorhynchos, Neotropic Cormorant Phalacrocorax brasilianus), which has been
observed in Bocas del Polochic, Punta de Manabique and El Paraíso-La Barrona.
Hunting is forbidden in protected areas, but management deficiencies prevent effective
controls and sufficient surveillance in the areas.
Commercial and sport ocean fisheries are serious threats for seabirds, which are subjects of
bycatches. An account of critical fishery methods in the Pacific region was published by U.S. Fish and
Wildlife Service (2005). Estimates suggest that hundredthousands of seabird are killed annually in the
Pacific (U.S. Fish and Wildlife Service 2005). To my knowledge, the impact of fisheries on seabirds
foraging in Guatemalan waters has not been studied. An international action plan to reduce the
incidental catch of seabirds was published by FAO (1999).
Introduced species
Worldwide most cases of extinction of bird species since 1800 were caused by introduced species
(BirdLife International 2000). In Guatemala, the extinction of the Atitlan Grebe has been attributed
partially to the introduction of largmouth bass (Micropterus salmoides), which reduced the grebe's food
resources (LaBastille 1974, 1984). Cattle is non-native in Guatemala and large-scale cattle farming of
half-wild herds is a major cause of deforestation in Guatemala, threatening especially waterbirds
which are specialized in wooded wetlands.
Water pollution
Human population in Guatemala is growing, which consequently increases the production of waste
and sewage. Sewage treatment is underdeveloped nationwide (Spillman et al. 2000). Major dying of
fish has been observed in the Río Motagua (Grupo Seguridad y Justicia 2003) and the watershed of
the Amatitlán Lake has been labeled as the most polluted in Guatemala (CEPAL 2002). Additional to
urban sewage, habitats are contamined by agricultural runoffs with pesticids and nutrients, discharges
from industry and mining activities. Eutrophycation can be assumed through an increased input of
nitrogen due to extensive forest fires (Fig. 23) and cattle ranching. Oil exploitation has caused habitat
contamination (e.g. ParksWatch 2003, 2005).
Sea pollution with petroleum products has threatened seabird populations worldwide (e.g.
Page et al. 1990, U.S. Fish and Wildlife Service 2005). In Guatemala, oil ports are located on both the
Atlantic and the Pacific coast (Santo Tomás, Champerico, Puerto San José). Additional potential
threats to Guatemalan off shore waters and coasts are oil transports between the USA and southern
Central and South America (U.S. Fish and Wildlife Service 2005). Robles (1999) reported the
formation of a committee for disaster prevention in ports on the Guatemalan Atlantic coast. There is
currently no institutional control on pollution in off shore waters by international oversea traffic.
Disturbance of roosting and foraging sites
Increased human disturbance on roosting and foraging sites of waterbirds causes the birds to flee
more often, which consequently causes an increased energy consumption. Especially migratory birds
can be affected considerably; energy deficiencies on the wintering and staging grounds may lower
individual fitness and breeding success in the subsequent nesting period. Increased movements are
assumed in all areas with high hunting activity (Sipacate-Naranjo, Manchón-Guamuchal, Bocas del
Polochic). Aggregations of hundreds of Great Egrets (Ardea alba) and American White Pelicans

Waterbird Conservation for the Americas Country Report for Guatemala
34
(Pelecanus erythrorhynchos) in shallow lagoons in Monterrico have been observed fleeing due to local
fishermen and boats with tourists (pers. obs.), a kind of traffic which occurs daily. The Guatemalan
Pacific coast is a popular destination for national tourists. Weekend houses have been built along the
coastline between Monterrico and Hawaii in the last decade. Leisure time activities include riding four-
wheel motorcycles along the beaches, riding water-motorcycles, and the use of ultra-light aircrafts
along the beach; negative effects on shorebirds are assumed.
Management deficiencies
Guatemala has a large system of protected areas which covers 30% (3,356,341 ha) of the country
(CONAP 2005). Some of the reserves are in fact unprotected due to management deficiencies; the
worse case is symbolized by Laguna del Tigre National Park and Biotope (ParksWatch 2003b, 2005).
Guatemala's national budget for protected areas was in 2005 ~USD 4.2 million (Pellecer 2005), which
equals one US Dollar and 30 Cents per ha of protected area. Costa Rica has 1,195,740 ha of
protected areas (EarthTrends 2003) and the 2005 budget for them was at USD 26 millions (Pellecer
2005), which equals USD 21.7 per ha. The low budget in Guatemala does not allow sufficient
surveillance in the reserves; one park guard covers on average 9,282 ha (Pellecer 2005).

General lack of environmental consciousness in the Guatemalan society
People throwing trash wherever they move, farmer families living in crude oil contaminated areas, fish
dying caused by water pollution from major factories, and people invading protected areas are
indicators of a lack of environmental consciousness in Guatemala, caused by lack of education, lack
of political will, social injustice, and poverty. The rate of analphabetism in Guatemala among the
population aged 15 years and over was 28.2% in 2004, which is the second highest value in Latin
America and the Caribbean after Haiti (CEPAL 2005). In 2002, 60.2% of the Guatemalan population
lived in poverty, having incomes amounting to less than the cost of a basic food basket (CEPAL
2005). Habitat destruction in Guatemala happens because of basic need of subsistence food
production within many rural communities. On the other hand, it happens through ignorance and
violation of legal frame works, in order to perform major business (e.g. cattle farming, mining and oil
exploitation), supported by the lack of institutional control and political will. Many environmental
punishable acts in Guatemala remain exempt from legal judgment and punishment (Boueke 2004,
CALAS 2005b, E. Cifuentes en Calito 2006).
Infectious diseases
Infectious diseases can be serious threats to bird populations, e.g. avian botulism (Adams et al. 2003),
West Nile Virus (Peterson et al. 2004), or avian influenza. In 2003 the first cases of an atypical avian
influenza (H5N1) have been documented in poultry in several Asian countries (CDC 2005) and its
transmission from bird to human has been reported (Apisarnthanarak et al. 2005). However, the risk of
transmission from bird to human is very low, but future mutation of the virus may cause transmission
between humans (CDC 2005, Mott 2005). Waterbird populations are facing a twofold threat by the
H5N1 virus: 1. The influenza may cause epidemic death among bird populations. 2. Incorrect
interpretation of scientific results on the different forms of avian influenza, virus distribution and wrong
information in medias (e.g. TV, radio, press, internet) may cause direct persecutions and mass killings
of migratory waterbirds as supposed dangers for human health and life. Persecution of animals based
on beliefs have occurred, and are occurring in owls, bats, snakes, and other groups. Direct
persecution of certain species may cause their local extirpation or extinction (Primack 1993).
Climate change
Climate changes are likely to become a major issue also for waterbirds. Human-induced global
warming is altering the global water regime (Wigley et al. 1997, Karl & Trenberth 2003). The increase
of sea surface temperature and atmospheric water vapor may enhance tropical storms and rainfall
(Trenberth 2005), which may cause decrease in breeding success of waterbirds, especially of species
which nest near the coast. Further changes in microclimate due to deforestation may cause drying out
of wetlands, and rising sea levels (Meehl et al. 2005, Wigley 2005) will alter the coastal landscapes.
Changes in migratory behavior due to climatic changes have been reported in some European bird
species (Stock 2005). Primary ecosystem productivity was reported to be reduced during unusual hot
weather situations in Europe (Ciais et al. 2005), which affects waterbird habitat and food resources.

Research activities
Ornithological research is underdeveloped in Guatemala. Past studies have been summarized in the
section "Background". FDN is establishing a waterbird monitoring in the Bocas del Polochic Wildlife
Refuge, with currently inappropriate methods (García 2004, García de la Vega 2005).
Monitoring and indicators
There is no nation-wide monitoring carried out currently.
Conclusions and recommended conservation action for species of special
concern
Basic conditions are favorable for waterbird conservation in Guatemala: 30% of the country territory
are declared as protected areas and the legal framework is established with laws on protected areas,
environment, and hunting. Guatemala has also signed international conventions on wetlands, ocean
conservation, and biological diversity. Nevertheless, natural habitats including wetlands are
threatened by major deficiencies in the application of existing frameworks. Urgent action is needed in
order to save important sites like Laguna del Tigre National Park. This will require changes in the
national political attitude in order to fulfill national and international responsibilities. Achieving a
change in the short term is a difficult issue which might be possible by strengthening the non-
governmental sector. Many protected areas in Guatemala are co-administrated by non-governmental
organizations. In order to improve effectiveness of NGO's, rigorous evaluations by donors or
independent third parties should be part of each project supported, which is currently not a usual
procedure. The National Council for Protected Areas (CONAP) is currently planning to implement a
conservation plan in communities adyacent to wetlands (Calito 2006).
In order to fill gaps in our knowledge on waterbirds in Guatemala, all conservation action
should be accompanied by appropriate research. Most areas lack even basic data; with few
exceptions, there are no data available on reproduction of waterbirds. Population sizes presented in
this report are guessed, based on very few data. The performance of a basic field study across the
whole country establishing baseline data for continuous monitoring is recommendable. While
knowledge on waterbird populations can be generated in the short term, developing environmental
consciousness is a long-term goal, which can be achieved only by environmental education.
It follows a summarizing account of proposed conservation action for species of special
concern (listed in Table 3, here without extinct or probably extinct species), grouped by habitat. First
and foremost, most of these species would benefit from management improvements in and around the
protected areas. Although the number of park guards was recently elevated in several protected areas
(F. Herrera, pers. comm.), surveillance is still underdeveloped. Sustainable land use in and outside of
protected areas has much been discussed, but there is actually no conclusive large scale concept.

This account includes punctual actions in order to improve short-term conservation on some hotspots.
To achieve long-term conservation and indeed address threats listed in the previous chapter "Issues
and threats to waterbirds and their habitats" requires complex improvements among the Guatemalan
society, which are out of scope of this report, but which must include:
• Education: an elevated educational level would rise the environmental consciousness and
lower the rate of human population increase. Both are key factors of all threats.
• Management of public enterprises (government, communities) according to applying laws and
frameworks (emission control, waste water and sewage treatment, etc.).
• Once public enterprises are managed appropriately, public control over private enterprises
may be reforced.
When key sites are mentioned, refer also to the specific section in "Locations and descriptions of key
sites used y aquatic species" for details.
Offshore seabirds (Procellaria parkinsoni, Puffinus creatopus, Puffinus nativitatis, Puffinus
ilherminieri, Oceanodroma tethys, Sula sula): Visiting populations need to be monitored and a
fisheries observation program should be installed, possibly in coordination with the other Central
American countries.
Near shore and estuary seabirds (Pelecanus occidentalis, Larus heermanni, Xema sabini,
Sterna elegans, Sterna dougallii, Sterna hirundo, Sterna antillarum, Chlidonias niger): Probable
nesting sites (Brown Pelican) require documentation and special protection. Visiting populations need
to be monitored and a fisheries observation program should be installed.
Birds of shores, marshes, and savannahs (Burhinus bistriatus, Charadrius collaris,
Himantopus mexicanus, Catoptrophorus semipalmatus): Most shorebirds depend on mud flats as
feeding grounds during migration. Repeated disturbance (flushing causes increased energy
consumption) by human activities (e.g. fisheries, sport hunting, tourism) should be controlled at all
sites along the Pacific coast. Half-wild cattle moving a long the beach in Punta de Manabique are
threatening probably nesting Collared Sandplovers by trampling.
Waterbirds mainly of wooded wetlands, incl. mangrove (Tigrisoma mexicanum, Butorides
virescens, Agamia agami, Nycticorax nycticorax, Nyctanassa violacea, Cochlearius cochlearius,
Aramides axillaris, Heliornis fulica, Eurypyga helias): Further deforestation in Laguna del Tigre
National Park and in mangroves of Sipacate Naranjo, Manchón Guamuchal, and Monterrico-Hawaii
need to be prevented. First attempts to implement mangrove conservation by sustainable and
alternative landuse along the Guatemalan Pacific coast have been made (Cordero Pérez et al. 2000)
with limited success. The impact of the bilateral program "ALIANZAS" between El Salvador and
Guatemala is still limited in Guatemala (C. Muccio, pers. comm.).
Non-specialized waterbirds of freshwater wetlands and salt marshes (Cairina moschata,
Dendrocygna autumnalis, Dendrocygna bicolor, Nomonyx dominicus, Oxyura jamaicensis,
Podilymbus podiceps, Podiceps nigricollis, Botaurus pinnatus, Botaurus lentiginosus, Ixobrychus
exilis, Ardea alba, Egretta thula, Egretta caerulea, Egretta tricolor, Egretta rufescens, Platalea ajaja,
Jabiru mycteria, Mycteria americana, Laterallus exilis, Rallus limicola, Amaurolimnas concolor,
Porzana flaviventer, Pardirallus maculatus, Aramus guarauna): Sport hunting needs to be controlled in
Manchón-Guamuchal and Bocas del Polochic. Overharvest of fish needs to be addressed in Bocas
del Polochic, Monterrico-Hawaii (here also shrimps), Punta de Manabique, Petexbatún, El Pucté.
Annual reed burning in Monterrico should be prevented.

Acknowledgments
This report is based in many parts on a recent compilation on avian diversity in Guatemala
(Eisermann & Avendaño 2006), which was supported by a multitude of persons and institutions.
Please consult the long list of supporters in the mentioned publication. I want to thank WCS Petén,
especially Roan Balas McNab and José Soto, for their help organizing the waterbird workshop in
Petén. The workshop in Guatemala City was held in the National Museum of Natural History "Jorge
Ibarra". Both workshops would not have been possible without the organization by Claudia Avendaño,
who also helped gathering information on waterbird conservation in Guatemala. Many thanks to all of
them for their participation and input of unpublished data and ideas. I appreciate the support by
Rovoham Monzón on specific GIS issues. Comments and critical reviews by Oliver Komar, Claudia
Avendaño, Cristina Morales, Rebecca Zarza, Rob Clay, and Franklin Herrera improved this report.
