About These Birds
Taiga Bean Goose
A large brown goose with dark head and neck, orange-and-black bill, and orange legs. One of two bean goose species. Breeds in Scandinavian and Russian taiga; winters in western and central Europe. Recognized as separate from Tundra Bean Goose since 2007.
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.
