About These Birds
Swan Goose
A large long-necked goose with warm brown body, pale underparts, a dark brown cap, and a long straight black bill. The ancestor of the Chinese domestic Swan Goose breed. Wild populations are declining sharply. Breeds in Mongolia and Siberia; winters in eastern China. Endangered in the wild.
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.
