Abstract

A cross-sectional study of migrating raptors aged from 1 to 27 years old shows that migratory performance gradually improves with age and is driven both by selective mortality and individual improvement, with younger birds leaving progressively earlier as they age and becoming more proficient at coping with adverse environmental conditions, such as unfavourable winds.
