Trichomonas gallinae , a protozoan parasite infecting a wide range of birds, has been a cause for conservation concern since its recognition as an emerging infectious disease, having had notable impacts on several avian species, including causing widespread mortality in greenfinches ( Chloris chloris ), and chaffinches ( Fringilla coelebs ), and hi...

In Europe, many bird populations have undergone strong declines over the last decades. The European Turtle Dove is an iconic declining bird species that can be legally hunted in ten EU countries, with hundreds of thousands of birds being harvested annually in western Europe alone. The European Union urgently required from these member states to tac...

The European Turtle Dove Streptopelia turtur is a trans‐Saharan migratory species that has been declining for decades. This study reports nesting habitat, nest site characteristics, nesting success (38.6%) and productivity (2.40 young / pair / season) of European Turtle Doves radio‐tracked in a deciduous forest of Western France. A matrix populatio...

Agricultural changes in recent decades have led to a widespread loss of biodiversity, with habitat loss considered as the main factor in the decline. The European turtle dove is one of the farmland birds that has declined markedly in Europe, leading the IUCN to downgrade its status in 2015 from “Near Threatened” to “Vulnerable”. Knowledge of how ha...

Conservation of migratory birds requires knowledge of breeding and nonbreeding ranges and the connections between them. European turtle doves ( Streptopelia turtur ) are Palearctic-African long-distance migrants with wintering areas in the Sub-Saharan belt that are classed as vulnerable due to strong population declines. However, detailed non-breed...

Cracidae is the most threatened avian family in the Neotropics, mainly because of habitat destruction, heavy hunting pressure and poaching. In French Guiana, Black Curassows are heavily hunted, although basic knowledge of the ecological and demographical traits of the species remains limited. Such a gap prevents any attempt to assess the impact of...

Diseases can play a role in species decline. Among them, haemosporidian parasites, vector-transmitted protozoan parasites, are known to constitute a risk for different avian species. However, the magnitude of haemosporidian infection in wild columbiform birds, including strongly decreasing European turtle doves, is largely unknown. We examined the...

Significance Globally, seabird populations are in decline. Without long-term monitoring, realistic conservation goals are difficult to establish. Here, we use lake sediment records to reconstruct the long-term dynamics of an important colony of Leach’s Storm-petrels. We show that this seabird population underwent moderate natural population fluctua...

With a decline exceeding 30% over three generations, the once-common European Turtle-dove is now considered globally threatened by IUCN. As a legal game species in 10 European countries, the recent International Single Species Action Plan for this species highlighted the need to carry out an assessment of the sustainability of current levels of hun...

Among seabirds, alcids are particularly sensitive to bycatch in fisheries and oil pollution, yet their distribution at sea remains scarcely known in most of their breeding areas. GPS telemetry data of fifteen individuals of alcids (5 Razorbills 6 Common Murres and 4 Puffins) were analyzed to determine their distribution during the breeding period o...

Background Understanding how past climatic oscillations have affected organismic evolution will help predict the impact that current climate change has on living organisms. The European turtle dove, Streptopelia turtur, is a warm-temperature adapted species and a long distance migrant that uses multiple flyways to move between Europe and Africa. De...

Satellite telemetry of two European Turtle Doves Streptopelia turtur confirmed the broad patterns suggested by earlier work using geologgers but also revealed that they migrated by night and used four distinct stopover and two wintering sites. Winter habitat used by one bird covered less than 100 km2 per site, much smaller than previously assumed.

We document the mortality of terrestrial bird species wintering in France as a result of the 2012 February cold spell. We describe the range of species affected and how some of them reacted to the cold spell in term of movement and variation in body mass. Mortality records concerned 1,791 individuals from 42 species. Among terrestrial birds, Northe...

The identification of migration routes, wintering grounds and stopover sites are crucial issues for the understanding of the Palearctic-African bird migration system as well as for the development of relevant conservation strategies for trans-Saharan migrants. Using miniaturized light-level geolocators we report a comprehensive and detailed year ro...

The St Pierre and Miquelon Archipelago hosts the only French Leach's Storm-Petrel (Oceanodroma leucorhoa) colony. We conducted a survey during the 2008 breeding season to estimate the breeding population size on Grand Colombier Island. This survey included an estimation of burrow detection probability using a double-observer approach. We estimated...

Originaire des Indes, la tourterelle turque est devenue en l’espace de quelques décennies une espèce familière de l’avifaune européenne et Nord-américaine. L’amplitude et la rapidité de son expansion à travers ces deux continents au cours du siècle dernier comptent parmi les phénomènes les plus fascinants observés chez une espèce d’oiseau. Retour s...

Capsule Earlier broods tend to be more male biased than later broods

Summary • Quantifying connectivity between breeding, stopover, and wintering locations is critical to the management and conservation of migratory animals. Mark–recapture approaches to establishing connectivity are limited due to marking location bias and poor recovery. Alternatively, endogenous markers like stable isotopes can augment extrinsic ma...

Resumen. La Isla Europa es un importante lugar de reproducción de tortugas verdes (Chelonia mydas; 0.7 a 2.4 millones de tortugas juveniles eclosionan allí anualmente), así como de Fregata minor (700 a 1100 parejas reproductivas) y F. ariel (1000 a 1200 parejas). Por medio de observaciones visuales, cuantificamos la proporción de machos, hembras y...

The function and causes of kidnapping juveniles are little understood because individuals sustain some breeding costs to rear an unrelated offspring. Here we focus on the proximal causes of this behaviour in emperor penguins (Aptenodytes forsteri), whose failed breeders often kidnap chicks. We experimentally tested the hypothesis that kidnapping be...

The ‘division-of-labour’ hypothesis predicts that males and females perform different roles in parental care and that natural selection acts differently on each sex so as to produce different body size optima suited to their particular roles. Reversed sexual size dimorphism in avian species (females larger than males) may therefore be an adaptive c...

For birds breeding in temperate areas, territoriality and courtship co-occur during spring and are mirrored by elevated plasma levels of luteinizing hormone (LH) and testosterone. By contrast, several tropical species show no major changes in LH and testosterone throughout the year and plasma levels are often low. This study describes changes in bo...

Successful application of stable-hydrogen isotope measurements (δDf) of feathers to track origins of migratory birds and other wildlife requires a fundamental understanding of the correlation between δDf and deuterium patterns in rainfall (δDp) over continental scales. A strong correlation between δDp and δDf has been confirmed for birds and insect...

The participation of both sexes to parental care have been studied in two different frigatebird species: the Great Frigatebird (Fregata minor), exhibiting a clear sexual size dimorphism, and the Lesser Frigatebird (Fregata ariel), with little sexual size dimorphism. Our results show that Great Frigatebirds perform an unequal division of labour duri...

We studied several determinants of laying date variation and the relationship between laying date and reproductive success in the Snow Petrel Pagodroma nivea. The effects of female body size and condition, year, individual laying period, colony size, mate fidelity, previous reproductive success, and duration of the pre-laying exodus on laying date,...

We studied seasonal and inter-annual variations in the diet, amount of food delivered to chicks, and body condition of chicks and adult red-tailed tropicbird at Europa Island (Mozambique Channel, Indian Ocean), during 3 consecutive seasons. The diet consisted of epipelagic fishes (13 families) and squid (3 families) totalling 32 taxa. Three familie...

Plasma levels of corticosterone often mirror changes in body condition and parental effort. In seabirds, the brooding of young chicks is often paralleled by a marked decline in adult body condition. This may reflect the trade-off between the needs of the chick to be fed regularly and brooded, and that of the adult to spend enough time at sea to res...

Prolactin levels rapidly drop after breeding failure in several terrestrial bird species, but in penguins prolactin secretion can be maintained well after failure. We measured prolactin secretion in relation to reproductive failure in a tropical seabird, the Red-footed Booby (Sula sula). Incubation failure was recorded in 7 nests (2 accidental loss...

Europa Island is a major breeding place for green turtles (Chelonia mydas; 0.7 to 2.4 million juvenile turtles hatch there annually), Great Frigatebirds (Fregata minor; 700 to 1100 breeding pairs), and Lesser Frigatebirds (Fregata ariel; 1000 to 1200 pairs). By visual observation, we quantified the proportions of males, females, and juveniles of bo...

Plasma levels of luteinizing hormone, prolactin, testosterone, and progesterone were measured throughout breeding in masked boobies, red-footed boobies, and red-tailed tropicbirds at Europa and Tromelin Islands (Indian Ocean). LH secretion showed a dampened pattern in the three species, particularly in tropicbirds. Such specific differences may be...

Plasma levels of luteinizing hormone (LH) and prolactin associated with parental behavior were measured in the Antarctic winter breeding emperor penguin,Aptenodytes forsteri.Males exclusively incubate the egg while females exclusively brood the nonhomeothermic young; both sexes alternate in rearing the homeothermic young. Birds were sampled on arri...

Contexte du programme On a longtemps considéré les espèces animales comme « utiles » lorsqu'elles étaient gibiers ou avaient une valeur commerciale ou comme « nuisibles » lorsqu'elles présentaient une menace pour l'Homme et ses biens. Cette vision a considérablement évolué (Charlez ,1993) et à partir des années 1960 des conventions internationales...
