A diminutive fowl, it is barely larger than a domestic Mallard. In fact, one might be tempted to misidentify a white park duck as this species. The bill and feet are pink, not orange, and the stubby bill is thicker like a goose and not flat like a duck. Important, too, are the black wingtips of this and Snow Goose.
The Snow Goose is larger and has a bigger, longer bill. But a lone goose or family group, with no other waterfowl to compare with, can confuse.
The breeding range is the central Canadian Arctic and Hudson Bay. The main population from Arctic Canada winters in California; the population breeding around Hudson Bay winters in New Mexico, Texas, and adjacent Mexico.
