The birds of the Pacific Flyway depend on a diverse chain of habitats, from Arctic tundra and northwestern rainforest to tropical beaches and mangroves. Audubon’s network of chapters, volunteers, activists, and members is preserving and restoring these vital links along the way.
Each year at least a billion birds migrate along the Pacific Flyway, but these birds are only a fraction of those that used the flyway a century ago. Habitat loss, water shortages, diminishing food sources, and climate change all threaten the birds of the Pacific Flyway.
