The Spectacled Eider(Somateria fischeri) is a large sea duck that breeds on the coasts of Alaska and northeastern Siberia. At sea, eiders forage on clams, polychaete worms, and other organisms on the sea floor. In winter, the world population of Spectacled Eiders group at a single site south of St. Lawrence Island, Alaska, in the northern Bering Sea. In the summer, the species is divided into three breeding populations; western and northern Alaska and northern Russia.
