The Black Swan, Cygnus atratus is a large non-migratory waterbird which breeds mainly in the southeast and southwest of Australia. It is also found along the east coast of Australia, Tasmania and recently reintroduced in New Zealand. Prior to the arrival of the Māori, a sub-species known as the New Zealand Swan used to live in New Zealand. This subspecies was hunted to extinction. The Black Swan was formerly placed into a monotypic genus, Chenopis.

The Black Swan is commonly found in the wetlands of southern Australia. Unfortunately, human inhabitance has decreased the population of the swan. The current global population of the Black Swan is approximately around 500,000 individuals.


The Black Swan is 130cm (52in) long and weighs up to 9kg (20lbs). It has all black plumage, except for the red bill, dark grey legs and white tips of the wing feathers. The neck is long and curved in an "S". On its red bill, there is a white bar near the tip. Both sexes are similar, with female slightly smaller and lighter than male. The cygnets have light grey plumage. The beak—otherwise known as the bill or rostrum—is an external anatomical structure which serves as the mouth in some animals. ...

The Southern Hemisphere swan species differ from the all-white Northern Hemisphere swans in that they all have some black in the plumage, but only the Black Swan is almost completely black. However, its closest living relative is probably the Mute Swan which is most similar, except in body plumage. The Southern Hemisphere is the half of a planets surface (or celestial sphere) that is south of the equator (the word hemisphere literally means half ball). On Earth it contains five continents (Antarctica, Australia, most of South America, parts of Africa and Asia) as well as four oceans (South...

Every year, the adults moult and become flightless. During this time they gather on open lakes in flocks. The diet consists mainly of water plants and unlike many other waterbirds, they spend their entire lives in the area where they were hatched. In animals, moulting (Commonwealth English) or molting (American English) is the routine shedding off old feathers in birds, or of old skin in reptiles, or of old hairs in mammals (see also coat (dog)). In arthropods, such as insects, arachnids and crustaceans, moulting describes the shedding of its exoskeleton (which...


As with other swans, the Black Swan is largely monogamous, pairing for life. It nests on large mounds build in the middle of a shallow lake and reuses the same nest each year, restoring or rebuilding it as needed. Male and female swans share the care of the nest, and once the cygnets are fledged, it is not uncommon to see whole families looking for food. In monogamy (Greek: monos = single/only and gamos = marriage) a person has only one spouse at a time (as opposed to polygamy). ...


Black Swans were discovered by the expedition of Willem de Vlamingh to the west coast of Australia in 1697. Their discovery created great interest in Europe, where "all swans are white" had long been used as a standard example of a well-known scientific truth. Willem de Vlamingh (born 28 November 1640, died ?) was a Dutch sailor who explored the southwest coast of Australia (then New Holland) in the late 17th Century. ...
