Black swan

The black swan (Cygnus atratus) is a large waterbird, a species of swan which breeds mainly in the southeast and southwest regions of Australia. Within Australia, the black swan is nomadic, with erratic migration patterns dependent on climatic conditions. It is a large bird with black plumage and a red bill. It is a monogamous breeder, with both partners sharing incubation and cygnet-rearing duties. Black swans can be found singly, or in loose companies numbering into the hundreds or even thousands. It is a popular bird in zoological gardens and bird collections, and escapees are sometimes seen outside their natural range. The black swan was introduced to various countries as an ornamental bird in the 1800s, but has managed to escape and form stable populations. This bird is a regional symbol of both Western Australia, where it is native, and the English town of Dawlish, where it is an introduced species.
