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.
Cockatiel
The cockatiel is the smallest member of the cockatoo family and one of the most popular pet birds globally. These gentle, intelligent parrots can learn to whistle tunes and mimic sounds. Wild cockatiels are nomadic, traveling in flocks following food and water availability across the Australian outback.
