Millions of seabirds, endemic species that only nest here, and Asiatics that blow in with storms or spring and fall migration.
More than a millions birds nest on each of these refuge islands, St. George in the Pribilofs, Kiska, Chagulak, St. Matthew, Forrester and the Semidis. Another island, Buldir, is also in the "millionaire" class but is closed to the public to protect Steller sea lions. Other, more accessible, islands host at least a quarter million nesting seabirds such as St. Lazaria near Sitka, the Barren Islands near Homer, and Egg Island near Unalaska. Adak is a destination for spring and fall migrants blowing ashore from Asia (see Adak Bird List)
