About These Birds
Meller's Duck
A large brown dabbling duck resembling a female Mallard but larger, with green iridescent speculum and orange bill. Endemic to Madagascar. Endangered; threatened by hunting and wetland loss. One of Madagascar's rarest 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.
