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.
Green Pygmy-goose
A tiny dark-green duck with pale spotted underparts, a dark cap, and a short stout bill. Endemic to New Guinea and northern Australia. Found on water-lily-covered billabongs and lakes. Feeds by snatching seeds and petals of aquatic plants from the surface.
