About These Birds
Pacific Black Duck
A large brown dabbling duck with a distinctive bold head pattern: dark crown, buff cheeks with two dark stripes, and a green speculum. The Mallard equivalent in Australasia. Widespread and common in Australia, New Zealand, New Guinea, and Pacific islands. Very tolerant of human presence.
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.
