About These Birds
Ferruginous Duck
白眼潜鸭是以雄鸟鲜明白色眼睛命名的中型潜鸭，繁殖于欧洲中部至中亚，越冬于地中海、中东和印度次大陆。雄鸟头颈胸部栗褐色，腹部白色，眼睛白色；雌鸟相似但眼睛褐色。由于湿地丧失和猎捕，被列为近危物种，在部分地区数量大幅下降。
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.
