About These Birds
Blue-winged Goose
A medium-sized grey-brown goose-like duck with distinctive pale blue-grey wing patches visible in flight. Endemic to the Ethiopian Highlands. Grazes on short grass near mountain rivers and streams. Monogamous; pairs are permanent. Threatened by agricultural intensification and overgrazing.
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.
