About These Birds
Grey Teal
A small grey-brown teal with fine pale edging on feathers, red eye, and green speculum. Widespread and common in Australia and New Zealand. Highly nomadic in Australia; follows inland flooding. Found in a wide variety of freshwater habitats from permanent lakes to temporary claypans.
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.
