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.
Scaly-sided Merganser
A medium-large merganser (~1.1 kg) in family Anatidae, distinguished by scaly flank patterning and a shaggy crest. Breeds along fast, clear rivers in old-growth forests of far eastern Russia and China; winters in rivers of East and Southeast Asia. Feeds on fish. Endangered due to deforestation, river pollution, and human disturbance of nesting sites.
