Thank you to our backers for $5600! We actually need up to $24000 - please keep donating! In the fall, most birds must pause to refuel at stopover sites where they consume fruits that are rich in antioxidants and fat. The ability of a bird to refuel may affect its ability to continue or successfully complete a migration. Our project will examine how condition (e.g. antioxidant and fat stores) on stopover may affect the behavioral decisions birds make during migration.
