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.
Cape Shoveler
A medium-sized shoveler with a characteristic large spatula-shaped bill. Males have yellow-orange eyes, brown head, and spotted brownish body; females are mottled brown. Endemic to southern Africa. Found mainly on the Western Cape's lakes and saline pans.
