About These Birds
Crested Duck
A large grey-brown Andean duck with a slightly shaggy crest on the nape, long neck, and bronze-and-black speculum. Found along fast-flowing Andean rivers and high-altitude lakes. Highly territorial; pairs defend stretches of river or lakeshores. Feeds by dabbling and upending.
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.
