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.
Torrent Duck
A slim agile duck perfectly adapted to fast-flowing Andean rivers. Males are striking with a white-and-black-streaked head, red bill, and chestnut breast; females are rufous below. Forages by diving and swimming in violent rapids, holding on to boulders with strong claws. Monogamous with strong site fidelity.
