About These Birds
Black Swan
The black swan was once considered impossible by Europeans who believed all swans were white, making it a famous philosophical example of inductive reasoning failure. It is the state emblem of Western Australia. Black swans form lifelong pair bonds and both parents share in incubation and care of cygnets.
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。
