About These Birds
White-winged Duck
A large dark duck with a pale speckled head, brownish body, and broad white wing patch visible in flight. One of Asia's most endangered ducks. Found in undisturbed lowland forest near rivers in South and Southeast Asia. Nests in large tree hollows. Threatened by deforestation and hunting.
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.
