Three subspecies of Black-tailed Godwit share non-breeding sites in the world's largest river delta

During the non-breeding season (September–April), Black-tailed Godwits (Limosa limosa) are commonly seen in coastal and inland wetlands of the Ganges-Brahmaputra-Meghna Delta in Bangladesh. We hypothesize...

Negative effects of artificial nest boxes on birds: A review

Artificial nest boxes are placed to attract birds to nest and breed in a specific location, and they are widely used in avian ecology research and in the attraction of insectivorous birds. There is...

Chinese Blackbirds (Turdus mandarinus) mimic electric moped sounds with lower consistency and frequencies

Passerine mimics often imitate various vocalizations from other bird species and incorporate these sounds into their song repertoires. While a few anecdotes reported that wild songbirds imitated human-associated...

Vultures as a model for testing molecular adaptations of dietary specialization in birds

Vultures are the only obligate scavengers among extant vertebrates. They provide valuable ecological services in ecosystems through removing carcasses, thus preventing the growth of other scavenger...

Correlates of avian extinction timing around the world since 1500 CE

Avian extinctions have been relatively well documented in modern history, and in the past millennia, more bird species are known to have gone extinct than species in any other vertebrate class. We examined...

Shallow water habitats provide high-quality foraging environments for the Spoon-billed Sandpiper at a critical staging site

Abundant food supply is crucial for the survival of long-distance migratory birds. The continued population decline of the Spoon-billed Sandpiper (Calidris pygmeae), a critically endangered shorebird,...
