About These Birds
Emperor Goose
皇帝雁是一种中型海雁，繁殖于阿拉斯加西部及西伯利亚东北部，越冬于阿留申群岛沿岸。头部和颈背白色，颈前黑色，形成鲜明对比。主要栖息于海滨苔原和沿海滩涂，以草地植物和海藻为食。受栖息地变化和气候变暖的影响，种群数量已有所下降。
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.
