About These Birds
White-faced Whistling-duck
A tall elegantly built whistling-duck with a conspicuous white face, chestnut body, barred flanks, and a distinctive three-note whistle. Widespread in sub-Saharan Africa and South America. Forms large noisy flocks at freshwater sites. Highly gregarious; roosts and nests communally.
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.
