Migratory songbirds rely on specific stopover habitats to rest and refuel during journeys of thousands of kilometers, and the quality of these sites directly determines individual bird welfare and survival.
Individual migratory songbirds arriving at degraded stopover sites without adequate food resources face exhaustion-induced death or must continue migration in depleted condition that increases mortality risk. The welfare of individual birds during migration is critically dependent on the chain of stopover habitats connecting their breeding and wintering grounds. Restoring native plant communities at stopover sites, reducing building lighting during peak migration nights, and preventing window strikes collectively improve the welfare of billions of migrating songbirds each spring and fall.
