About These Birds
Lesser Whistling-duck
A small warm brown whistling-duck with chestnut upper-tail coverts, a pale face, and dark brown cap. The most widespread and common whistling-duck in Asia. Found in freshwater wetlands from the Indian subcontinent to Southeast Asia. Nests in holes in trees and sometimes in thatched roofs.
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.
