About These Birds
Pink-footed Goose
A compact short-necked goose with a pink-and-black bill, pink feet, and warm brown-grey body. Breeds in Greenland, Iceland, and Svalbard; winters in northwestern Europe. One of Britain's most spectacular winter visitors; massive roosts of over 200,000 birds occur in Scotland.
