About These Birds
Tufted Duck
凤头潜鸭是欧亚地区最常见的潜鸭之一，以雄鸟头顶长而下垂的黑色羽冠为特征。广泛繁殖于欧亚大陆北部，越冬于英国、地中海和亚洲南部。雄鸟黑白相间，羽冠明显；雌鸟褐色，羽冠较短。善潜水，以贻贝等软体动物、昆虫和植物种子为食。
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.
