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.
Magellanic Steamerduck
A large flightless steamerduck with grey-blue plumage, a rust-orange head (male), and massive orange-red bill. Named for its habit of steaming across water using wings and feet. Found on rocky Patagonian coasts and sheltered channels. Among the world's heaviest ducks at up to 6 kg.
