===Introduced populations===
====New Zealand====
[[File:Black Swan in Flight Crop.jpg|thumb|In flight]]
Before the arrival of the [[Māori people|Māori]] in [[New Zealand]], a related species of swan known as the [[New Zealand swan]] had developed there, but was apparently hunted to [[extinction]]{{citation needed|date=April 2025}}. In 1864, the Australian black swan was introduced to New Zealand as an ornamental waterfowl and populations are now common on larger coastal or inland lakes, especially [[Lake Rotorua|Rotorua Lakes]], [[Lake Wairarapa]], [[Lake Ellesmere / Te Waihora]], and the [[Chatham Islands]].<ref name = Falla/> Black swans have also naturally flown to New Zealand, leading scientists to consider them a native rather than exotic species, although the present population appears to be largely descended from deliberate introductions.<ref>{{cite web|author=Narena Olliver |url=http://www.nzbirds.com/birds/blackswan.html |title=Black Swan (New Zealand birds) |publisher=Nzbirds.com |date=2010-10-28 |access-date=2011-10-17}}</ref>

====United Kingdom====
The black swan is also very popular as an ornamental waterbird in western [[Europe]], especially [[Great Britain|Britain]], and escapees are commonly reported. As yet, the population in Britain is not considered to be self-sustaining and so the species is not afforded admission to the official British List,<ref>{{cite web |url=http://blx1.bto.org/birdfacts/results/bob20800.htm |title=BirdFacts – Black Swan |publisher=[[British Trust for Ornithology|BTO]] |access-date=2009-11-06 }}</ref> but the [[Wildfowl and Wetlands Trust]] have recorded a maximum of nine breeding pairs in the UK in 2001, with an estimate of 43 feral birds in 2003–2004.
A small population of black swans exists on the [[River Thames]] at [[Marlow, Buckinghamshire|Marlow]], on the brook running through the small town of [[Dawlish]]  in [[Devon]], near the [[River Itchen, Hampshire]], and the [[River Tees]] near [[Stockton on Tees]].<ref>{{cite web|url=http://www.wildlifeextra.com/go/news/black-swan.html#cr|title=Archant – Inspiring Communities|access-date=2015-07-21|archive-url=https://web.archive.org/web/20150502223544/http://www.wildlifeextra.com/go/news/black-swan.html#cr|archive-date=2015-05-02|url-status=dead}}</ref> The Dawlish population is so well associated with the town that the bird has been the town's emblem for forty years.<ref>{{Cite web |title=Dawlish Waterfowl |url=https://dawlish.com/article/details/9 |access-date=2024-09-02 |website=dawlish.com |language=en}}</ref>

====Japan====
There are also wild populations in [[Japan]], having originally been imported during 1950–1960.<ref>{{Cite web |title=Cygnus atratus / Invasive Species of Japan |url=https://www.nies.go.jp/biodiversity/invasive/DB/detail/20480e.html |access-date=2024-09-02 |website=www.nies.go.jp}}</ref><ref>{{Cite web |last=Brazil |first=Mark |date=2001-07-05 |title=Beauty versus the environment |url=https://www.japantimes.co.jp/life/2001/07/05/environment/beauty-versus-the-environment/ |access-date=2024-09-02 |website=The Japan Times |language=en}}</ref><ref>{{Cite web |last=Sawa |first=Takamitsu |date=2011-02-21 |title=Swan dive into the strait dividing economic views |url=https://www.japantimes.co.jp/opinion/2011/02/21/commentary/swan-dive-into-the-strait-dividing-economic-views/ |access-date=2024-09-02 |website=The Japan Times |language=en}}</ref>

Black swans have been reported in [[Florida]], but there is no evidence that they are breeding; persistent sightings may be due to continual releases or escapes.<ref>{{Cite web |last=mauroossa |date=2020-08-04 |title=Cisne Negro/Black Swan/Cygnus atratus |url=https://birdscolombia.com/2020/08/04/cisne-negro-black-swan-cygnus-atratus/ |access-date=2024-09-02 |website=Birds Colombia |language=es}}</ref> [[Orange County, California]] reported black swans in [[Lake Forest, California|Lake Forest]], [[Irvine, California|Irvine]] and [[Newport Beach, California|Newport Beach]] on October 5, 2020, and [[Santa Ana, California|Santa Ana]] in December 2021 in the “Versailles on the Lake” apartment community.{{citation needed|date=July 2022}} The "Lake Forest Keys” community bought the original swans about eight to ten years ago and since then there have been many births and gaggles from the original couple" according to a report in the ''[[Orange County Register]]''.<ref>{{Cite web|url=https://www.ocregister.com/2020/10/05/why-are-so-many-black-swans-native-to-australia-showing-up-in-local-waters/|title = Why Australia's black swans are showing up in Orange County|date = 5 October 2020}}</ref><ref>{{Cite web|url=https://myfwc.com/media/19646/bba_blsw.pdf|title=Black Swan – Cygnus atratus|date=6 April 2020|website=Florida Fish and Wildlife Conservation Commission|access-date=6 April 2020}}</ref> Black swans formerly resided in the vicinity of [[Lake Junaluska]], a large lake in [[Waynesville, North Carolina]].<ref>{{Cite web|url=http://www.smokymountainnews.com/archives/item/14150-malcolm-s-swan-song|title=Malcolm's swan song|last=Morrison|first=Jeremy|date=27 August 2014|website=Smoky Mountain News|access-date=8 June 2017}}</ref>
