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.
Maned Duck
An elegant medium-sized duck with a grey body, chestnut-spotted breast in males, brown head with a short mane, and short grey bill. Endemic to Australia; also called the Australian Wood Duck. Grazes on grass in open woodland and pastures near water. Highly adaptable; common in urban parks and golf courses.
