About These Birds
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.
Surf Scoter
丑鸭（白头黑海番鸭）因雄鸟嘴部具大型橙白色斑块，似戴眼镜而得名。全身黑色，嘴部橙白黑三色，头部具白色和锈色斑点；雌鸟褐色。繁殖于北美北部泰加林的湖泊，越冬于北太平洋和大西洋沿岸。善深潜，以软体动物和甲壳类为食。
