About These Birds
Pink-eared Duck
A small highly specialized duck with a large spatula-shaped bill for filter-feeding, grey-brown plumage with bold facial stripe, and a tiny pink patch behind the eye. Endemic to Australia. Highly nomadic; follows inland flooding. Expert filter-feeder on microscopic algae and invertebrates.
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.
