The spectacled eider 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 (20-22 inches) 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. The female is a rich brown bird, but can still be readily distinguished from all ducks except other eider species on size and structure. The paler goggles are visible with a reasonable view and clinch identification. Immature birds and eclipse adult drakes are similar to the female.
