Avian ecology and behavior

The paper constructs a global seabird foraging guild database, identifies 22 diets and 30 strategies, and shows the Gusein-Zade model fits guild structure distributions.

This study examines how bird diversity in a farmland mosaic in Northeastern Portugal changed during a period of both agricultural intensification and land abandonment from 1980-2000.

This study tracks migration routes and wintering sites of Aquatic Warblers in Lithuania and North Belarus using geolocators, revealing most overwinter in Mali's Inner Niger Delta with some in Senegal and Burkina Faso.

The paper examines brood division in Formicivora acutirostris, finding it reduces drowning risk, spatially divides food consumption, and allows concurrent reproduction, with implications for climate change impacts.

This study uses long-term banding data to show that 86% of boreal songbirds in Alaska advanced their autumn migration timing by ~2-3 days per decade, with site-specific variations linked to climate indices.

The paper develops an ecological clustering method to delineate natural populations using population dynamics data from North American birds, identifying 2-5 populations per species for 160 species.

The paper develops an improved estimator for bird abundance by combining point and transect observations, validated through simulations and confidence interval analysis.

This study examines visual concealment and nest-site selection in Yellow-wattled Lapwings, finding no link between camouflage mechanisms and hatching success, but identifying preferences for high vegetation cover and low food availability.

The paper examines how social flocking behavior in two bird species changes with environmental conditions, finding that social clustering increases in harsher climates.

This study examines the ecological and public health impacts of poultry production and consumption waste on urban raptors and scavengers in Delhi, highlighting climate, disease, and pandemic-related effects.

The paper estimates bird diversity in Southwest West Bengal, India, identifying 343 species and 55 new records using point count methods and citizen science.

The paper examines the relationship between seabird body size and foraging specialization, finding negative scaling exponents and proposing a model based on ecological principles.

The paper assesses insect availability for meadow bird chicks using image analysis of sticky traps across two years, finding increased insect counts in 2018 but no correlation with management practices.
