The paper assesses avian communities and soundscapes along an Amazonian river using acoustic monitoring and machine learning, finding taxonomic diversity peaks at river edges while functional structure remains consistent.

Opening a standardized, spatially contiguous biodiversity database collected over 40 years: Czech breeding bird atlases 1973-77, 1985-89, 2001-03, and 2014-17

The paper releases a long-term, standardized biodiversity dataset of Czech breeding birds spanning 40 years, providing spatially contiguous records for ecological and ornithological research.

The impacts of seventy years of changes in stopover habitats on the critically endangered Spoon-billed Sandpiper Calidris pygmaea

This study examines how 70 years of habitat changes affected Spoon-billed Sandpiper populations in Japan, finding that natural habitat loss had a stronger negative impact than artificial wetland expansion.

Stage-specific habitat use of the Mountain Plover in Colorado, USA

The paper investigates stage-specific habitat use of Mountain Plovers in Colorado, finding that vegetation structure, not food availability or predation risk, best explains nest and brood site selection.

Human land-use change drives co-occurrence of ecologically similar avian aerial insectivores in Southeast Asia

The paper evaluates how human land-use change, particularly nest farms, affects niche partitioning and competition among six sympatric swiftlets and swallows in Northern Borneo.

Feather corticosterone is not associated with feather growth rate or quality across tropical and temperate passerines, but possibly linked to elevation

This study examines the relationship between corticosterone levels in feathers and feather growth rate or quality across passerine birds, finding no association but suggesting elevation may influence corticosterone levels.

Landscape heterogeneity as a main driver of avian population dynamics

This study examines how landscape heterogeneity and environmental factors influence bird population dynamics over 25 years in Poland, finding that long-term spatial constraints and habitat heterogeneity are key drivers.

ANTHROPOGENIC AND VEGETATION FACTORS SHAPE RED-CHEEKED CORDON-BLEU ABUNDANCE IN A NIGERIAN SAVANNA LANDSCAPE

This study examines how human activity and vegetation affect Red-cheeked Cordon-bleu bird abundance in Nigerian savannas, finding that building density and vegetation structure are significant predictors.

SPATIAL HABITAT DIFFERENCES DRIVE ABUNDANCE OF RED-CHEEKED CORDON-BLEU IN HUMAN-MODIFIED LANDSCAPES

This study finds that farmlands support higher abundance of Red-cheeked Cordon-bleu than human settlements in Nigerian savannas, likely due to better vegetation and less disturbance.

The AvianMetaNetwork: biotic interactions among birds of the continental United States and Canada

The paper constructs a comprehensive dataset of 25,907 bird-bird interactions across North America to address macroecological and eco-evolutionary questions.

Drone Survey Reveals a Severe Chinstrap Penguin Decline and a Novel Gentoo Colony in an Antarctic Specially Protected Area

The paper uses drone surveys to assess population changes in three seabird species in an Antarctic protected area, finding a significant decline in Chinstrap Penguins and growth in Gentoo Penguins and Antarctic Shags.
