About These Birds
Trumpeter Swan
号天鹅是北美最大的本土水鸟，体重可达12千克以上。全身白色，嘴部全黑，以飞行时发出低沉的号角般鸣叫而得名。繁殖于阿拉斯加和加拿大西部，越冬于美国西部沿岸地区。曾因羽毛交易而濒临灭绝，经保护措施后数量已恢复。以水生植物、谷物为食。
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.
