Early-Life Group Size Does Not Influence Japanese Quails' Learning in a Response Inhibition Task

This study examines how early-life group size affects response inhibition in Japanese quails, finding that larger groups reduce pecking time but do not impact learning rates.

Metabolic responses to cold: thermal physiology of native common waxbills (Estrilda astrild)

This study examines the metabolic responses of common waxbills to cold temperatures in their native range, identifying a metabolic inflection point at 16°C that may indicate an adaptive energy-saving strategy.

Beyond a unitary construct: Dissecting stopping behaviour in two bird species

This study examines stopping behaviour in two gull species using three tasks, finding species-specific differences linked to migration and foraging strategies.

Metabolic adjustments to winter severity in two geographically separated great tit (Parus major) populations

This study compares winter metabolic rates in two great tit populations, finding differences in basal and maximum metabolism that challenge the aerobic capacity model.

Seasonal variation in great tit (Parus major) energy requirements: reallocation versus increased demand

This study examines energy requirements in great tits during winter and breeding seasons, finding no substantial difference in energy expenditure, supporting the reallocation hypothesis.

Host-pathogen co-existence incurs reproductive costs

This study shows that host-pathogen co-existence in pigeons leads to reduced reproductive success but protects against clinical disease.

Body size and tree species composition determine variation in prey consumption in a forest-inhabiting generalist predator

This study shows that body size and tree species composition influence prey consumption in orb-weaving spiders, with larger spiders consuming larger prey and tree diversity affecting prey richness.

How many bird and mammal extinctions has recent conservation action prevented?

The paper estimates that conservation actions prevented 21-32 bird and 7-16 mammal extinctions between 1993-2020, and 9-18 bird and 2-7 mammal extinctions between 2010-2020.
