About These Birds
Reunion Shelduck
留尼汪麻鸭（Alopochen kervazoi）是一种曾特产于印度洋留尼汪岛的已灭绝麻鸭。属鸭科（Anatidae），仅凭亚化石骨骼和历史记录得知，因人类定居后引进的哺乳动物掠食和猎捕而灭绝。
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.
