Eiders are large seaducks in the genus Somateria. Steller's Eider, despite its name, is in a different genus.
The three extant species all breed in the cooler latitudes of the Northern hemisphere.
Species
- Common Eider The Common Eider, Somateria mollissima, is a large sea-duck, which is distributed over the northern coasts of Europe, North America and eastern Siberia. It breeds in Arctic and some northern temperate regions, but winters somewhat farther south in temperate zones, when it can form large flocks on coastal waters Somateria mollissima
- Spectacled Eider Somateria fischeri
- King Eider Somateria spectabilis
Two undescribed species are known from fossils Fossils are the preserved remains or traces of animals, plants, and other organisms from the remote past. The totality of fossils, both discovered and undiscovered, and their placement in fossiliferous (fossil-containing) rock formations and sedimentary layers (strata) is known as the fossil record. The study of fossils across geological time, how, one from Middle Oligocene The Oligocene is a geologic epoch of the Paleogene period and extends from about 33.9 million to 23 million years before the present. As with other older geologic periods, the rock beds that define the period are well identified but the exact dates of the start and end of the period are slightly uncertain. The name Oligocene comes from the Greek rocks in Kazakhstan Kazakhstan , officially the Republic of Kazakhstan, is a country in Eurasia ranked as the ninth largest country in the world. It is also the world's largest landlocked country. Its territory of 2,727,300 km² is greater than Western Europe. It is neighbored clockwise from the north by Russia, China, Kyrgyzstan, Uzbekistan, Turkmenistan, and also and another from the Late Miocene The Miocene is a geological epoch of the Neogene period and extends from about 23.03 to 5.33 million years before the present . The Miocene was named by Sir Charles Lyell. Its name comes from the Greek words μείων (meiōn, “less”) and καινός (kainos, “new”) and means "less recent" because it has 18% fewer modern sea or Early Pliocene The Pliocene epoch is the period in the geologic timescale that extends from 5.332 million to 2.588 million years before present of Lee Creek Mine, USA ^ b. English is the de facto language of American government and the sole language spoken at home by 80% of Americans age five and older. Spanish is the second most commonly spoken language. The former may not actually belong into this genus.
