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-backed Duck
A small compact brown-barred diving duck with a distinctive white back visible in flight and a large dark-blotched bill. Shy and easily overlooked among floating aquatic vegetation. An expert diver, feeding on water-lily seeds and tubers in African freshwater wetlands.
