About These Birds
Wandering Whistling-duck
A medium-sized whistling-duck with rufous-brown body, dark brown back, pale buff underparts, and a chestnut collar. Found in tropical wetlands from Indonesia to Australia and Pacific islands. Highly social and nomadic. Forages by dabbling and diving in shallow freshwater.
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.
