|[[File:Cisne (Cygnus olor) en el Palacio de Nymphenburg, Múnich, Alemania30.JPG|120px]]
|''Cygnus olor''
|[[Mute swan]]
|Eurasian species that occurs at lower latitudes than the whooper swan and Bewick's swan across Europe into southern Russia, China and the Russian Maritimes. Recent fossil records, according to the [[British Ornithologists' Union]], show ''Cygnus olor'' is among the oldest bird species still extant and it has been upgraded to "native" status in several European countries since this bird has been found in fossil and bog specimens dating back thousands of years. Common temperate Eurasian birds, often semi-domesticated descendants of domestic flocks, are naturalised in the United States and elsewhere.
|Europe into southern Russia, China and the Russian Maritimes; introduced populations in North America, Japan, Australasia and southern Africa.

|[[Black swan]]
|Nomadic with erratic migration patterns dependent upon climatic conditions. Black plumage and a red bill.
|Australia, introduced into New Zealand and the [[Chatham Islands]], with additional smaller introductions in Europe, the United States, Japan and China.

|''Cygnus cygnus''
|[[Whooper swan]]

|Breeds in Iceland and subarctic Europe and Asia, migrating to temperate Europe and Asia in winter

|[[File:Trumpeter Swaw (Cygnus buccinator) RWD1.jpg|120px]]
|''Cygnus buccinator''
|[[Trumpeter swan]]
|The largest North American swan. Very similar to the whooper swan (and sometimes treated as a subspecies of it), it was hunted almost to [[extinction]] but has since recovered.
|North America

|[[File:Bewick's Swans at Big Waters.jpg|120px]]
|''Cygnus columbianus''
|[[Tundra swan]]
|Breeds on the Arctic tundra and winters in more temperate regions of [[Eurasia]] and North America. It consists of two forms, generally considered to be subspecies but considered separate species by some authorities.<ref>{{cite web | title=Overzicht van alle vogels waargenomen in Nederland | website=Dutch Avifauna | url=https://www.dutchavifauna.nl/list. | language=nl | access-date=2025-05-17}}</ref>
* Bewick's swan ''Cygnus'' (''columbianus'') ''bewickii'' is the Eurasian form that migrates from Arctic Russia to western Europe and eastern Asia (China, Korea, Japan) in winter.
* Whistling swan ''Cygnus'' (''columbianus'') ''columbianus'' is the North American form.
|North America, Eurasia

The [[coscoroba swan]] (''Coscoroba coscoroba'') from South America, the only species in its genus, is not a true swan. Its phylogenetic position is not fully resolved; it is in some aspects more similar to [[Goose|geese]] and [[shelduck]]s.<ref>{{Cite web |url=https://www.zoo.org/page.aspx?pid=1842#.V6a615MrI6g |title=COSCOROBA SWAN |archive-url=https://web.archive.org/web/20160808082000/https://www.zoo.org/page.aspx?pid=1842 |archive-date=8 August 2016}}</ref>
