The article I selected is ‘Non-breeding season events influence sexual selection in a long-distance migratory bird’ for this study. This article talked about how the non-breeding season events (like different quality of overwintering habitats) change the sexual selection factors (like departure time, polygyny, and nest conditions, etc.) of migratory birds.
This is an academic, peer-reviewed research material as the source has been reviewed by at least 1 referee before publication, which could be proved by the end of conclusion: We gratefully acknowledge the many field assistants who contributed to this study.
