About These Birds
Madagascar Teal
马岛鸭（Anas bernieri）是一种小型褐色鸭，体羽具细密斑点，眼睛红色，具蓝绿色翼镜。特产于马达加斯加，属鸭科（Anatidae），是马达加斯加最濒危的水禽之一，受到栖息地丧失威胁。
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.
