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.
Muscovy Duck
疣鼻栖鸭原产于中南美洲热带地区，是家番鸭（又称番鸭）的野生祖先。嘴基和眼周具红色疣状皮肤，体型大，雄鸟体重可达4千克。栖息于热带森林的河流和湖泊，在树洞中营巢。家养品种已遍布全球，野生种群因栖息地丧失和猎捕而数量减少。
