Golden eagles regularly use gravity waves to soar in the Alps: new insights from high-resolution weather data

This study shows golden eagles in the Alps use gravity waves for soaring, contributing to 19% of their flight segments and becoming primary updraught sources in winter.

Urbanization as an environmental filter for megacolorful birds

The paper examines how urbanization affects plumage colorfulness in tropical birds, finding that megacolorful species are less common in highly urbanized areas.

Functional and Taxonomic Diversity of Avian Communities Across Land-Use Gradients in Wayanad Using eBird Data

This study uses eBird data to analyze bird diversity across land-use gradients in Wayanad, finding that natural habitats support more diverse and specialized bird communities compared to agricultural and urban areas.

This study surveys bird diversity in Shola Sky Islands of the Western Ghats, finding higher diversity in larger, less isolated mountain ranges and highlighting conservation needs.

Decreased female survival may explain wild turkey decline

This study investigates population declines in wild turkeys by analyzing changes in female survival rates and their impact on population growth.

Using wingbeat frequency to estimate mass gained by seabirds

This paper estimates mass changes in seabirds using wingbeat frequency and biologging data to assess foraging success and energy intake.

Space use fidelity of non-territorial vulturine guineafowl groups is shaped by both environmental and social processes

This study examines how environmental and social factors influence space use consistency in non-territorial vulturine guineafowl groups.

Bird population trend analyses for a monitoring scheme with a highly structured sampling design

The paper develops a GAMM-based workflow to analyze bird population trends from structured monitoring data, addressing spatial bias, observer variation, and zero-inflation, and validates it against existing methods.

Biologically inspired warning patterns deter birds from wind turbines

This study tests if biologically inspired warning patterns on wind turbine blades deter birds, finding that aposematic patterns significantly reduce approach behavior in great tits.

Eucalyptus cover as the primary driver of native forest bird reductions: evidence from a stand-scale analysis in NW Iberia

This study shows that eucalyptus plantations reduce native forest bird abundance and richness, with eucalyptus cover being the main driver, due to limited resources like cavities and arthropods.
