Avian ecology and behavior

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

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.

This study updates the population estimate for northern gannets in the North-East Atlantic after a 2022 HPAI outbreak, showing a 17% decline in occupied sites.

The paper estimates hornbill abundance and habitat correlates in Kali Tiger Reserve, finding Malabar Grey Hornbills are most abundant and widely distributed, with encounter rates linked to food-tree density.

The paper examines how energy availability and habitat heterogeneity influence bird diversity in Finland and suggests conservation strategies based on these findings.

This study assesses climate vulnerability in an alpine bird species by linking population density to habitat features across multiple timescales.

This study links wind pattern oscillations to seabird movements at multiple scales, showing adult albatrosses adapt to wind patterns while younger birds are more affected by synoptic-scale winds.

The paper compiles over 3500 quantitative raptor diet records from 1000 studies into a database with metadata on location, time, and prey species.

This study examines diet and reproductive productivity in European Shags at two Portuguese colonies, finding that environmental factors influence diet and that prey biomass affects reproductive success.

The paper reassesses the historical record of Pionus fuscus in Colombia using multiple lines of evidence, concluding it does not occur there.

This study examines how climate variables affect nestling development in two Patagonian bird populations, finding that climate impacts hatch weights but not growth rates or pre-fledging weights.

This study examines how climatic factors affect embryonic development in thorn-tailed Rayadito birds, finding that northern populations are more vulnerable to climate change than southern ones.

This study compares space use and survival of hand-reared and wild juvenile herring gulls, finding differences in habitat preferences and range size but no survival difference.

This study examines how biodiversity can be supported in dense urban areas by analyzing bird species richness and composition in Gothenburg, finding that local habitat area and connectivity are key factors.

This study shows that rising temperatures in Oman's hyper-arid desert caused reproductive collapse in Golden Eagles, with near-zero reproduction beyond 28.3-28.6°C, indicating climate-driven functional extinction.

The paper estimates the 2025 Red Knot stopover population at Delaware Bay using a Bayesian Jolly-Seber model and finds a 17% increase from 2024 with stable migration timing.

This study shows that active restoration of logged tropical forests in Borneo leads to persistent declines in forest-dependent bird species compared to naturally regenerating forests.

The paper analyzes long-term changes in body mass of great tits, finding that early-life environmental factors drive decreases in adult and nestling mass over 47 years.

This study shows a sharp decline in peregrine falcon nesting in California's San Francisco Bay region linked to an H5N1 avian influenza outbreak.

The paper compares passive and active survey methods for detecting Coturnix coturnix, finding that call playback significantly increases detectability, especially in low-density populations.

This study examines how Forest Owlets select habitats across multiple scales in Gujarat, finding that they thrive in agroforestry systems when certain conditions are met.

The paper examines how breeding timing, clutch size, and nesting strategy affect reproductive success in crested ibis over three seasons, finding significant declines with later breeding and positive clutch size effects.

This paper develops a Bayesian integrated population model to analyze Western Capercaillie population dynamics in Scotland, identifying key drivers of decline and evaluating management strategies.

The paper investigates crash-based mortality in northern gannets, finding wind direction predicts crashes and their demographic impact.

This study compares bird communities in urban lakes between Europe and South America, finding higher overall richness in South America but similar common species richness and higher dominance in Europe.
