Variation of migration routes in the central Asian-breeding Common Cuckoo population influenced by the Qinghai-Tibet Plateau
September 2025
Ecological barriers present significant challenges to bird migration by limiting the availability of stopover sites and shelters. The Qinghai-Tibet Plateau, a major migratory barrier located in higher...
The role of sterile apices of Puya chilensis (Bromeliaceae) on the nectar-feeding behavior of passeriform birds in central Chile
September 2025
The factors affecting the behavior of non-specialized nectar-feeding passerines have received little attention in the literature on plant-pollinator interactions. Puya chilensis (Bromeliaceae) has sterile...
Multi-dimensional niche segregation of sympatric breeding seabirds in the Xisha Archipelago

Studying coexistence mechanisms is practically important for understanding and conserving marine biodiversity and community structure. Tropical marine ecosystems may exhibit higher competition between...
Sri Lanka's laughingthrush: An ecological and phylogenetic assessment of a babbler confused for a laughingthrush
September 2025
The Ashy-headed Laughingthrush (Argya cinereifrons), a species endemic to Sri Lanka, has been historically considered a laughingthrush in the genus Garrulax. However, based on phylogenetic evidence,...
How nestlings of Oriental Reed Warbler respond to adult alarm calls
September 2025
Avian alarm calls mediate defenses against brood parasites and predators. These calls facilitate communication among adults and alert nestlings to potential danger. While heterospecific call recognition...
From fledging to independence: Post-fledging movements and space use of the Crested Ibis (Nipponia nippon)
September 2025
The post-fledging period, extending from fledging to independence, is a crucial life stage characterized by high mortality due to fledglings' limited mobility and inexperience. During this stage, fledglings...
Genomic evidence of hybridization between two species of Penduline Tits reveals postzygotic reproductive isolation
September 2025
Azure-winged Magpies breeding in urban areas can effectively reduce the risk of brood parasitism
September 2025
With the ongoing acceleration of global urbanization, an increasingly larger proportion of natural habitats are being transformed and utilized by humans. Urbanization has a substantial impact on animal...
Regional differences in wintering habitat selection strategies of Siberian Crane (Leucogeranus leucogeranus) and ecological network construction of key wintering areas
