About These Birds
Hardhead
A medium-sized diving duck. Males have rich chestnut-brown body, white eye, and blue-grey bill; females are similar but duller. Australia's only widespread diving duck. Nomadic; follows inland flooding. Forms large rafts on deep lakes.
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.
