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.
Red-breasted Merganser

Breeds near freshwater and coastal habitats across the Northern Hemisphere; winters in estuaries and coastal seas. Dives in pursuit of fish and invertebrates. Least Concern; one of the fastest flying ducks, reaching 100 km/h.
