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.
Falkland Steamerduck
A large flightless steamerduck endemic to the Falkland Islands, with grey body plumage, white belly, and orange-yellow bill. Males have a rust-orange head. Highly territorial and aggressive; pairs vigorously defend coastal territories. Feeds by diving in kelp beds and rocky coastal shallows.
