Birds' co-occurrence is mediated by diet, habitat type, and anthropogenic disturbances in Ghana's Central Region
September 2025
Understanding the fundamental drivers of large-scale species co-occurrence is a critical issue in ecology and conservation research. Here, we assessed foraging guilds, habitat type and disturbances...
Migration patterns and spatial connectivity of Pallas's Gulls (Ichthyaetus ichthyaetus) from Alakol lake, Kazakhstan using ring recovery and tracking data
September 2025
Understanding migration patterns and spatial connectivity is crucial for conserving long-distance migratory birds. While satellite telemetry has advanced the study of large gulls, Pallas's Gull (Ichthyaetus...
Elevated extinction risk of low-elevation populations of two songbirds on the Taiwan island
September 2025
Prevailing concerns on mountainous biodiversity are concentrated on the impacts of climate change at higher elevations. However, the lower elevations are facing additional human disturbance and are...
Evaluation of the visual signal in playback by territorial responses of nuthatches
September 2025
A playback experiment is a well-established method for behavior research, especially in the study of the territorial responses of songbirds. Birds obtain information from multimodal signals, whereas...
Testing urban edge effects: Nest predation rates are higher in areas further from the boundary of a suburban park
September 2025
Urban green spaces and parks offer opportunities for retaining and increasing bird richness, diversity, and species abundance. However, urbanisation influences predator–prey interactions, leading to...
Responses of steppe birds to habitat fragmentation: Insights from niche specialization and functional traits
September 2025
Habitat fragmentation poses a significant threat to bird communities, especially those in open and semi-open ecosystems such as steppes. This study investigates how steppe birds adapt to and utilize...
Climatic, topographic, and local-scale variables differently shape bird communities in urban streets and parks
September 2025
Green cover and human disturbance are important local factors shaping urban bird communities, while climatic and topographic variables can be important when analyzing cities in different biomes. However,...
Reconciling Bergmann's rule throughout the annual cycle in two congeneric large-bodied migratory waterbirds
September 2025
Bergmann's rule predicts that the larger of two homeotherm species differing only in size would occur at higher latitudes, or in cooler climates than the smaller, because of relative thermoregulatory...
Phylogeography of the endangered Yellow-headed Parrot (Amazona oratrix)
September 2025
Elucidating the historical processes that led populations to their current spatial and genetic arrangement is relevant in conserving threatened species. We interpreted the phylogeographic structure...
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...
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...
