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.
Common Scoter
A medium-sized sea duck (~1.1 kg) in family Anatidae, males entirely black with a knobbed yellow bill. Breeds on moorland lakes in northern Europe and western Siberia; winters in large flocks on shallow coastal seas. Dives for bivalves and crustaceans. Least Concern; monitored due to sensitivity to offshore energy development and oil spills.
