About These Birds
Cape Barren Goose
A large pale grey goose with a distinctive lime-green cere at the base of its short dark bill and pink legs. Endemic to southern Australia. Grazes on grasses and low scrub on offshore islands. Territorial and aggressive; pairs hold year-round territories. Can survive without fresh water.
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.
