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.
White-winged Scoter
A large diving duck (~1.6 kg) in family Anatidae, distinguished by white secondaries visible in flight. Breeds on freshwater lakes in boreal North America; winters along Pacific and Atlantic coasts. Dives for mussels, clams, and aquatic insects. Least Concern; North American populations remain broadly stable despite some local declines.
