About These Birds
Red-breasted Goose
A small strikingly patterned goose with a vivid chestnut-red breast and face patch, black-and-white body, and white flank stripe. Breeds in Siberian tundra; winters mainly around the Black Sea. One of the most colorful and endangered geese, threatened by hunting and agricultural changes at wintering sites.
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.
