Physical description Click here for a physical description Black Swans are large, almost all-black swans, with white primary and secondary flight feathers, a long, slender neck and a red bill with a white bar near the tip. The grey-brown edges of their feathers may give them a mottled appearance. Male Black Swans are taller than females. During their moult, Black Swans are flightless. Juveniles are scalloped light to mid-grey, paler than adults, with black tips on the primaries, and also a paler bill. Black Swan cygnets are all-grey.

Taxonomy, classification See Black Swan at Wikipedia .

Range, habitat, finding this species Click here for information on habitat and range The overall distribution of this species can be assessed, and specific locations where birds have been spotted can be found, based on individual sighting reports submitted by birdwatchers to ebird.org . The global distribution of the Black Swan is available HERE . The populations in western and central Europe and in New Zealand are introduced. Black Swans are endemic to Australia. Their range extends over more than half of the Australian continent. Depending on the availability of water, they can be found anywhere except the most arid regions, i.e. the major deserts in the western half of WA, the south-western corner of the NT and the eastern half of SA. They are most common along the eastern, south-eastern and south-western seaboard, most of the Great Dividing Range and the Murray-Darling Basin. Black Swans have a preference for fresh water habitats with open water surrounded by dense vegetation, such as lakes, swamps, mudflats and also dams lined with dense reeds. They will also stay in suitable wetlands in urban parks. Where to look? How to find this species? Black Swans are often found in shallow water with aquatic plants within their reach. Being large, black birds with a prominent pink bill, they are easy to spot from long distances. They can also be prominent when sitting on their nest because many nests, although protected by a body of water, are in plain sight.

Sightings Click here for sighting information Black Swans can be seen regularly in various types of wetlands in inland NSW, e.g. at Narrabri Lake. We have also spotted them in other locations in the Narrabri area after the significant rainfalls of May/June 2007. A small number stayed around Narrabri Lake throughout the winter of 2008. Seen also during the winter of 2010 and in the years since. Black Swans were also spotted by us at Goran Lake, an ephemeral lake about 30 km South of Gunnedah, NSW, when the lake was full in 2011/12. Black Swans were also found by C. Hayne at Whittaker's Lagoon, 20 km west of Moree, NSW, and many other wetlands in the area. Black Swans were seen by us as far inland as Walgett, NSW, in ephemeral wetlands in April 2009. They were also spotted by us in many locations in central QLD, in particular also, in large numbers, in the wetlands of Capricorn Resort, Yeppoon, in July 2009. Special access to the wetlands kindly granted by the owners of Capricorn Resort is most gratefully acknowledged. Later we have also spotted Black Swans in many locations along the NSW coast and in the northern tablelands (e.g. Dangars Lagoon near Uralla, NSW, and Mother of Ducks Lagoon NR, Guyra, NSW). We also saw some in the area of Geraldton, WA, in March 2003. Also seen on the banks of River Torrens (which forms a lake) in Adelaide, SA, by J. Thurmer in February 2009. Black Swans were spotted by us also at Currawinya NP in south-western QLD. They are also commonly found in wetlands in other parts of QLD, for example on the Gold Coast, as reported by A. & J. Ross-Taylor. R. Plumtree reports spotting Black Swans at Hollands Landing, Lake Victoria, East Gippsland, VIC, in October 2014. J. Greaves reports spotting Black Swans regularly in Perth, WA, and in other parts of WA. They were also spotted on Kangaroo Island, SA, in March 2016. K. White reports finding Chestnut Teals regularly at St Georges Basin on the NSW South Coast. R. Russell reports finding Black Swans at Mount Molloy, in far North QLD, in January 2015. C. Pears reports finding Black Swans regularly at various locations in Perth, WA, and semi-regularly in Quindalup, WA. However, although well within its range, at Cervantes, WA, D. Dyer only rarely finds the species. One Black Swan was seen there in May 2022, at the time the first in years. M. Eaton reports finding Black Swans breeding in St. Helens, TAS, in September 2021. J. Boettcher, FNQ Nature Tours found Black Swans at the Forever Wild Shared Earth Reserve, Mareeba, QLD, in October 2020.

ADULT

Many bird species exhibit sexual dimorphism, i.e., male and female have differing appearances which can be quite subtle.
The sexes of birds shown below were not determined by individual birds' appearances, but by comparison with a nearby partner. Male Black Swans are taller than females, but otherwise not distinguishable.

Behaviour

Social behaviour: Territorial/communal

Mobility: Nomadic

Elementary unit: Pair/family clan/flock

During the breeding season, male Black Swans fight over the right to find and mate with a partner. Outside the breeding season, Black Swans are more sociable, forming small flocks.

There is a separate page describing Black Swan courtship behaviour.
