The Emperor Goose (Anser
canagicus) is a species of goose. It breeds around the Bering
Sea, mostly in Alaska, USA, but also in Kamchatka, Russia. It
is migratory, wintering mainly in the Aleutian Islands. The American
ornithologist, David Sibley, places this species and the other
North American "white" geese in the genus Chen, rather
than the more traditional "grey" goose genus Anser.
The Emperor Goose is then classed as Chen canagica. This goose
has a stout grey body, subtly barred with fine barring, and a
white head and hindneck, often stained orange from iron-rich waters.
Unlike the blue morph Snow Goose, the white does not extend onto
the front of the neck. The sexes are similar, but immatures have
the head the same colour as the body.
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. Breeding birds moult near the breeding colonies,
but non-breeders move to St Lawrence Island to moult prior to
the main migration to the rocky coastines of the wintering grounds.
The food of this
goose is typically composed of shoreline grasses and other coastal
