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.
White-headed Steamerduck
A large flightless steamerduck with grey body and an entirely white head in males, found only along the Patagonian coast of Chubut Province, Argentina. One of the rarest ducks in South America; range extends for only about 400 km of coastline.
