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.
Emperor Penguin
体型最大、最重的企鹅。在南极冬季零下60摄氏度的环境中繁殖。雄鸟孵卵约65天，期间完全禁食。
