A medium-sized diving duck. Males have a rich chestnut-red head, black breast, and pale grey body; females are brown with a pale face. Widely distributed across Eurasia. Population declining sharply; Vulnerable on European Red List.
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.
