â€¢ Variation in migratory route and plumage color is explained by genomic variation
â€¢ A region on chromosome 4 is strongly and additively associated with orientation
â€¢ This region includes circadian, nervous system, and cell signaling genes
â€¢ Recurrent selective sweeps have shaped variation in this region
