Snow goose
species of bird
The snow goose (Chen caerulescens or Anser caerulescens), also known as the blue goose, is a North American species of goose. Its name comes from its white feathers. Some authorities place this species in the Chen genus.[1] Other authorities place these species in the "gray goose" genus Anser.[2] In addition to a white phase they also have a blue phase.[3] In the white phase they are all-white except for their primary feathers which are black. In the blue phase the head and upper neck remain white.[3]
