Greater White-fronted GooseAnser albifrons
In North America, this gray goose is found mainly west of the Mississippi River. Nesting on Arctic tundra, it winters in open country in mild climates. Wintering flocks leave night roosts before sunrise to fly to feeding areas, and musical gabbling and honking can be heard from wavering lines of White-fronts passing overhead at dawn. Included in this species is a large, dark form known as the "Tule Goose," nesting in southern Alaska and wintering in central California marshes.
