About These Birds
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.
Comb Duck
A large pied duck with a black-and-white body and, in males, a large black knob on the upper mandible during breeding season. The New World Comb Duck found from Panama to northern Argentina. Nests in tree cavities near lakes. Feeds by dabbling and grazing in wetland margins.
