The Black Swan is a native of Australia and Tasmania and is also found wild in New Zealand to where it was introduced.

It is the world's only black swan although its flight feathers, normally almost fully hidden at rest, are white.

The Black Swan is closely related to the Mute Swan (Cygnus olor) and the Black-necked Swan (Cygnus melanocorypha)
