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.
Flying Steamerduck
The only flying species among the four steamerducks, with grey plumage, rufous-washed head, and an orange-yellow bill. Can fly strongly unlike its relatives. Found in Patagonian freshwater and coastal habitats. Highly territorial; pairs defend stretches of river or lakeshore aggressively.
