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.
Baikal Teal
A strikingly beautiful teal with intricately patterned golden, green, black, and white head; pink-brown breast; and grey flanks. Breeds in Siberian taiga; winters in East Asia. Once seriously depleted, now recovering. Forms spectacular flocks of hundreds of thousands at South Korean wintering sites.
