Egyptian Goose
A large conspicuous sheldgoose-like bird with brown-and-white body, dark eye patches, a chestnut patch on the chest, and pink bill and legs. Native to Africa and the Nile Valley; widely introduced to Europe. Aggressive and territorial; found in urban parks. Feeds by grazing on grass.
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.
