The East Atlantic Flyway is a migration route used by about 90 million birds annually, passing from their breeding areas in United States Canada, Greenland, Iceland, Siberia and northern Europe to wintering areas in western Europe and on to southern Africa.

Wetlands International has identified key sites on the flyway in the project Wings Over Wetlands.
