The snow goose (Chen caerulescens), consisting of both a white phase and blue phase (Blue Goose), is a North American species of goose commonly collectively referred to as "light geese". Its name derives from the typically white plumage. Some authorities place this species in the more traditional grey goose genus Anser.
