Spectacled Eider Somateria fischeri

This peculiar Arctic sea duck breeds on the tundra in Alaska and far eastern Russia and winters in massive flocks among pack ice in the Bering Sea. Males have a unique olive-green head with white goggles, a dark breast, and a carrot-orange bill. Females are brown overall with pale goggles. Rarely seen away from a few key sites in Alaska, usually in small numbers. Compare with other eider species; even the dullest young females have pale goggle pattern on head.
