spectacled eider

The spectacled eider (pronounced /ˈaɪ.dər/) (Somateria fischeri) is a large sea duck that breeds on the coasts of Alaska and northeastern Siberia.

The spectacled eider is slightly smaller than the common eider at 52–57 cm (20.5–22.5 in) in length. The male is unmistakable with its black body, white back, and yellow-green head with the large circular white eye patches which give the species its name. The drake's call is a weak crooning, and the female's a harsh croak.
