Range Extent CommentsBREEDING: islands and coasts of Chukchi and Bering seas from Diomede Islands and Cape Lisburne south to the Aleutian Islands; from the Alaska Peninsula south to British Columbia; northeastern Siberia to the Kurile Islands; also Cooper Island, just east of Point Barrow, Alaska (see Johnson and Herter 1989).
