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.
Radjah Shelduck
A medium-sized elegant shelduck with white body plumage, chestnut breast band, dark green back, and pinkish-red bill and legs. Found in coastal mangroves, mudflats, and tropical wetlands of New Guinea and northern Australia. Calls with a loud raspy rattling sound.
