Natal legacies cause social and spatial marginalization during dispersal

B Catitti, MU Grüebler, DR Farine… - Ecology Letters, 2024 - Wiley Online Library
Early‐life experiences can drive subsequent variation in social behaviours, but how
differences among individuals emerge remains unknown. We combined experimental …

Turning tables: food availability shapes dynamic aggressive behaviour among asynchronously hatching siblings in red kites Milvus milvus

B Catitti, UG Kormann… - Royal Society …, 2023 - royalsocietypublishing.org
