Migratory songbirds face exhaustion, starvation, and predation during extraordinary multi-thousand-mile journeys.
Songbird migration represents one of nature's most remarkable feats — tiny birds navigating thousands of miles guided by stars, magnetic fields, and memory. The welfare costs of migration are significant: exhaustion, starvation if adequate stopover habitat is unavailable, and disorientation by artificial light create mortality and suffering at scale. Many migrants complete Gulf crossings in exhausted, depleted condition — arriving in coastal areas desperate to feed and rest. Maintaining stopover habitat, reducing building lighting during migration, and protecting wintering habitat in the neotropics all directly reduce migration welfare costs.
