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.
Spectacled Duck
A large dark brown duck with distinctive white spectacle-like eye-rings, a pale buff face, and a prominent white speculum. Found in fast-flowing forest rivers of southern South America. Shy and elusive; inhabits clear rushing rivers through temperate forest. Also known as the Bronze-winged Duck.
