CIRCADIAN RHYTHMS AND ENVIRONMENTAL ADAPTATIONS IN BIRD MIGRATION: A COMPREHENSIVE REVIEW

Abstract

This paper explores the relationship between circadian rhythms, environmental adaptations, and long-distance migration in birds. Migratory birds undertake vast journeys across continents, relying on internal biological clocks and environmental cues to optimize their migration routes and timing. As climate change introduces unpredictability into these environmental cues, understanding how circadian rhythms regulate migratory behaviors is crucial. This paper reviews current research on the interaction between circadian rhythms, environmental factors like photoperiod and temperature, and the adaptations birds have made to cope with these challenges. The study highlights the importance of this relationship for bird conservation in the context of global environmental change.
