A small compact diving duck. Males have rich chestnut-brown head and body, white eye, and white undertail; females are duller. Found across Eurasia and Africa. Locally common on Mediterranean and Central Asian lakes; population declining. Near Threatened globally.
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.
