Wikipedia Abstract

The emperor goose (Chen canagica) is a species of goose. It breeds around the Bering Sea, mostly in Alaska, United States, but also in Kamchatka, Russia. It is migratory, wintering mainly in the Aleutian Islands. The species is listed as Near Threatened by the IUCN. The American Ornithologists' Union places this species and the North American "white" geese in the genus Chen, rather than the more traditional "gray" goose genus Anser. This species is much less gregarious than most geese, usually occurring in family groups. It breeds on coastal tundra, laying 3–7 eggs in a ground nest.
