Understanding bird migration through abnormal movements

Vagrant birds were historically neglected in migration research due to their rarity and the limitations of early tracking methods. Yet, growing research shows that vagrancy can help us better understand several aspects of bird migration and its consequences. In this talk, I will show how abnormal migratory movements can inform key processes in bird migration, including the colonization of new territories, the emergence of novel migration routes, and the navigation systems of migratory birds.
