The snow goose (Chen caerulescens), also known as the blue goose, is a North American species of goose. Its name derives from the typically white plumage. The genus of this bird is disputed. The American Ornithologists’ Union and BirdLife International place this species and the other “white geese” in the Chen genus,[2] while other authorities follow the traditional treatment of placing these species in the “gray goose” genus Anser.[3][unreliable source?]

This goose breeds north of the timberline in Greenland, Canada, Alaska, and the northeastern tip of Siberia, and winters in warm parts of North America from southwestern British Columbia through parts of the United States to Mexico.[4] It is a rare vagrant to Europe, but a frequent escape from collections and an occasional feral breeder. Snow geese are visitors to the British Isles where they are seen regularly among flocks of barnacle, Brent and Greenland white-fronted geese. There is also a feral population in Scotland from which many vagrant birds in Britain seem to derive.

In Central America, vagrants are frequently encountered during winter.
