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.
Mute Swan
The mute swan is one of the heaviest flying birds, with males weighing up to 14 kg. Despite its name, it is not truly mute, producing hissing, grunting, and snorting sounds. Mute swans form lifelong pair bonds and their aggressive defense of nesting territory is well known.
