Article
Rolanda J. Steenweg, Auteur ; Pierre Legagneux, Auteur ; Glenn T. Crossin, Auteur ; H. Grant Gilchrist, Auteur ; T. Kurt Kyser, Auteur ; Oliver P. Love, AuteurMany birds change their partners every year and pairing may occur before arrival on the breeding grounds. Early pairing strategies can benefit mates by strengthening pair-bonds and increasing the rate of pre-breeding resource acquisition, leadin[...]

Jocelyn Champagnon, Auteur ; Pierre Legagneux, Auteur ; Guillaume Souchay, Auteur ; Pablo Inchausti, Auteur ; Vincent Bretagnolle, Auteur ; François Bourguemestre, Auteur ; Laura Van Ingen, Auteur ; Matthieu Guillemain, AuteurIbis, 4-2016The survival of captive-bred individuals from release into the wild to their first breeding season is crucial to assess the success of reintroduction or translocation programmes, and to assess their potential impact of wild populations. However,[...]

Article
Matthieu Guillemain, Auteur ; Steven L. Van Wilgenburg, Auteur ; Pierre Legagneux, Auteur ; Keith A. Hobson, AuteurManagement of migratory game birds must be considered at the flyway scale. Flyway delineation has generally relied on ring recoveries, yet migratory connectivity between breeding and wintering grounds is often difficult to demonstrate due to low[...]
Article
Pierre Legagneux, Auteur ; Alice-Anne Simard, Auteur ; Gilles Gauthier, Auteur ; Joel Bety, AuteurMarkers are widely used to study behavior, migration, and the life history traits of birds such as survival, dispersal, and reproductive success. The presence of neck collars has been shown to impact the breeding propensity of adult female Great[...]
Article
Céline Arzel, Auteur ; Johan Elmberg, Auteur ; Matthieu Guillemain, Auteur ; Michel Lepley, Auteur ; Fabrice Bosca, Auteur ; Pierre Legagneux, Auteur ; Jean-Baptiste Nogues, AuteurTwo frequent assumptions about the evolution of long-distance migration in birds are that they travel long distances annually to reach food-rich areas for breeding, and that they time their migratory journey to be at staging sites when the latte[...]
Article
Pierre Legagneux, Auteur ; Robert G. Clark, Auteur ; Matthieu Guillemain, Auteur ; Cyril Eraud, Auteur ; Marc Thery, Auteur ; Vincent Bretagnolle, AuteurIridescent colours produced during moult likely play an important role in pair formation in birds. We sought to quantify geographic variation in such colouration in a duck species, Eurasian teal Anas crecca, in winter (when mating occurs) to eva[...]
Article
Vincent Marmillot, Auteur ; Gilles Gauthier, Auteur ; Marie-Christine Cadieux, Auteur ; Pierre Legagneux, AuteurEnvironmental constraints are strong in migratory species that breed in the Arctic. In addition to breeding, Anatidae have to renew all their flight feathers during the short arctic summer. We examine how temporal constraints and climate affect [...]
Article
Matthieu Guillemain, Auteur ; Céline Arzel, Auteur ; Pierre Legagneux, Auteur ; Johan Elmberg, Auteur ; Hervé Fritz, Auteur ; Michel Lepley, Auteur ; Christophe Pin, Auteur ; Antoine Arnaud, Auteur ; Gregoire Massez, AuteurMate guarding by males is common in species with long-lasting pair bonds. We tested if the need to guard females affected foraging depth in male teal (Anas crecca), and if they were more vigilant than females when foraging with submerged eyes (p[...]
Article
Pierre Legagneux, Auteur ; Martine Duhart, Auteur ; Vincent Schricke, AuteurDiet quantification has long been and still is one of the first steps undertaken when studying the basic ecology of a species. We conducted a literature review of the techniques used to study and analyse diet among waterfowl. Even though the ide[...]
Article
Pierre Legagneux, Auteur ; Holly L. Hennin, Auteur ; H. Grant Gilchrist, Auteur ; Tony D. Williams, Auteur ; Oliver P. Love, Auteur ; Joel Bety, AuteurTheoretically, individuals of migratory species should optimize reproductive investment based on a combination of timing of and body condition at arrival on the breeding grounds. A minimum threshold body mass is required to initiate reproduction[...]
Article
Pierre Legagneux, Auteur ; Christine Blaize, Auteur ; Franck LATRAUBE, Auteur ; Jerome Gautier, Auteur ; Vincent Bretagnolle, AuteurDespite a long historical record of radio-tracking analyses, basic home-range information is still lacking for most common waterfowl species, especially during the winter. We investigated how dabbling duck home ranges and daily foraging movement[...]
