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.
Mandarin Duck
The mandarin duck is widely considered the most beautiful duck in the world. In East Asian culture, mandarin ducks symbolize love and fidelity because they form strong pair bonds. Unlike most ducks, mandarins nest in tree holes up to 9 meters above the ground, and day-old ducklings must leap to the ground.
