The white and blue forms readily breed together, and the goslings from a single clutch can be either white or blue - sort of the way humans have brown or blue eyes. These birds are now known as the dark or blue morph of the Snow Goose. Ornithologists once believed these birds belonged to a separate species, called the Blue Goose. However, there are many Snow Geese with dark gray-bluish bodies.

Overall, the most common form has a snow-white body plumage. The Snow Goose occurs in different plumage colorations, known as morphs or forms. This is mainly because, as well as being a tundra nester, the Snow Goose tends to concentrate in key migration and wintering spots and thus is not as widespread.

This fact, however, is easily dismissed in fall and winter by people enjoying the sight of thousands of gleaming-white birds coming in to land at national wildlife refuges, including California's Salton Sea, New Mexico's Bosque del Apache, Texas's Anahuac, and Delaware's Prime Hook, as well as other wetland areas.Īlthough one of the world's most abundant waterfowl species, the Snow Goose is regularly seen by fewer people than is the familiar Canada Goose. This means that from about late March to late October, this is a wilderness bird. Like the Snowy Owl and Snow Bunting, the Snow Goose nests at the “top of the world” on tundra, much of it above the Arctic Circle.
