Cygnus atratus is the world’s only Black Swan. It has white, conspicuous flight feathers. The male’s bill and neck are longer and straighter than the female’s. The swans prefer large, permanent swamps and lakes with emergent and submerged aquatic vegetation. Their nests are large mounds of reeds, grasses and aquatic plants (Pizzey and Knight, 2003).
The black swan is a large waterbird, a species of swan which breeds mainly in the southeast and southwest regions of Australia. Within Australia they are nomadic, with erratic migration patterns dependent upon climatic conditions. Black swans are large birds with mostly black plumage and red bills. Wikipedia

Black Swans are widespread throughout much of Australia, and occur wherever there is a wetland, from river estuaries, bays and great lakes to inundated pasture and water-meadows. In some places, where the wetlands are permanent, Black Swans are sedentary, remaining throughout the year. However, where the wetlands dry out for part of the year, swans are forced to disperse over wide distances in search of suitable water, and have even been recorded swimming in isolated waterholes surrounded by vast tracts of arid stony desert.
