Snow Goose - Chen caerulescens Beak with shapr egdes.
THE SNOW GOOSE has two very different color forms. One is almost pure white, the other is a dark gray-blue. At one time, the blue form was thought to be a seperate species. Snow geese are powerful fliers, and they migrate every year to their breeding grounds in the far north.
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.
