Migratory birds often traverse thousands of kilometers, yet some individuals may abandon migration and form sedentary populations—a process termed ‘migratory drop-off’. A key limitation in studying this phenomenon is the inability to distinguish[...]

Human disturbances can have large impacts on wildlife and their behaviour. The extent of the effects of different kind of disturbances during different seasons is, however, less well known. Here, we assessed the impact of three different human d[...]

Among several threats, the food availability at stopover and wintering sites contributes to the decline of shorebird species. It is the case in the Pacific region, where the overwater journey for the migration is very long often without the poss[...]

Many birds sing prolifically during the dawn chorus and a subset of these species also sing at dusk. How vocal activity varies between these two periods has not been examined in many species. In this study, we explored rates of detection and son[...]

The Lesser Spotted Woodpecker Dryobates minor exhibits significant intraspecific variation across the Palearctic, with 13 recognized subspecies. This morphological variation has a large clinal component making subspecies boundaries somewhat arbi[...]

The Amazon is home to the greatest bird diversity in the world, but its avian diversity is still underestimated, partially due to cryptic diversity. An accurate assessment of cryptic species is necessary in order to construct a comprehensive inv[...]

Migration exerts a selective pressure for increased flight efficiency and reduced energy expenditure in long-distance migratory birds. In North America, eastern migratory flyways are longer and require flights over open seas, whereas western fly[...]
