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

[2] The United States population is an estimated 3,000–4,000 nesting pairs[3] The spectacled eider molts at sea anywhere from 2 to 45 kilometers (1.2 to 28.0 mi) from the shore and north of 63°N.

Fish and Wildlife Service originally listed the spectacled eider as Threatened because of a more than 96% drop in breeding population size in Alaska.

It is believed to be able to remain submerged longer than most diving ducks and mostly feeds on mollusks while at sea and aquatic insects, crustaceans, and plant material while on the breeding grounds.

Since spectacled eiders live in frigid areas that are not easily accessible to humans their main habitat loss has been a result of climate change.

A future threats to their habitat is the possible development of oil and gas drilling near Teshekpuk Lake which has well been established as a globally significant important bird area.
