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.
Blue-billed Duck
Australia's only endemic stiff-tailed duck (~840 g), family Anatidae, males recognized by deep chestnut plumage and a vibrant blue bill in breeding season. Inhabits deep freshwater lakes and swamps in southeastern and southwestern Australia. Dives for aquatic invertebrates and plant matter. Least Concern; dependent on permanent water bodies, vulnerable to drought cycles.
