🦅⁷•¹ Spectacled Eider (Somateria fischeri) in Swans, Geese, Ducks Family (Anatidae)

Описание: ▪︎ Spectacled Eider (Somateria fischeri) in Swans, Geese, Ducks Family (Anatidae) is a large sea duck that breeds on coasts of Alaska & northeastern Siberia.

Binomial commemorates German scientist Johann Fischer von Waldheim.

Is slightly smaller than Common Eider at 52-57 cm in length.

Male is unmistakable with its Black body, White back, & Yellow-Green head with large circular White eye patches which give species its name.

Drake's call is a weak crooning & Female's a harsh croak.

Female is a rich Brown bird, but can still be readily distinguished from all ducks except other eider species on size & structure. Paler goggles are visible with a reasonable view & clinch identification.

Immature birds & eclipse adult drakes (a male duck that has lost its bright feathers & is wearing a duller plumage) are similar to Female.
