The paper shows that blackcaps have shifted migratory direction due to warmer winters, using geolocator data and historical ringing records.

The paper uses a demographic model to show that productivity, particularly nest survival, drives population decline and male-biased sex structure in Common pochard.

This study examines how environmental factors affect body condition in European robins, finding sex- and age-specific declines linked to temperature and soil moisture, with impacts on survival and population trends.

The paper examines how foraging behavior, rather than prey identity, influences niche packing in tropical montane birds across an elevational gradient.

The paper analyzes long-term bird egg-laying data to show widespread phenotypic plasticity and recent evolution of plasticity in response to climate change.

The paper tracks changes in bird communities' interaction milieu over time, showing non-random structural shifts in association networks.

The paper uses satellite data and field surveys to predict bird communities in the Peruvian Amazon, finding that satellite-derived variables better predict species occurrence than habitat categories.

This study describes the first comprehensive analysis of egg development in the Crested ibis using candling, identifying critical periods of embryo mortality and providing a reference for conservation efforts.

This study uses national-scale passive acoustic monitoring to track avian migration patterns and develop species distribution models for three passerine species.

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.

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.

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.

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.

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.

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.

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.

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.

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

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.

This study examines habitat selection and movement patterns of Eurasian Woodcocks in Mediterranean regions, finding reduced use of open habitats and altered activity patterns compared to Atlantic-influenced areas.

The paper quantifies the conservation relevance of prebreeding seabirds by analyzing reproductive and survival rates across 84 species, finding they make up nearly half of populations and could be key to future stability.

The paper tests red-blade patterning at a South African wind farm and finds an 83% reduction in avian fatalities with strong statistical support.

This paper introduces a framework to scale BirdFlow models to 153 North American migratory bird species using integrated data, achieving biologically realistic movement predictions.

The paper develops order-level regression models to predict avian wingspan from wing length, providing estimates for 9,194 species with high accuracy.

This study examines 44 years of population trends in Capercaillie and Black grouse in central Sweden, linking changes to forestry, climate, and vole abundance.

This study examines how 13 British passerine bird species track a consistent incubation thermal niche across time and space, finding partial tracking across multiple axes but no difference between migrants and residents.
