Swan: ''Cygnus'' ''Coscoroba'' Swans are large water birds of the family (biology) Anatidae, which also includes goose and ducks. Swans are grouped with the closely related goose in the subfamily Anserinae. Swans usually mate for life, though "divorce" does sometimes occur, particularly following nesting failure. The number of eggs in each clutch varies both within and among swan species, typically between 3-8 eggs. Young swans are known as ''cygnets'', from the Latin word for swan, ''cygnus''. The male and female adults are known as ''cob'' and ''pen'', though these terms are little used nowadays. The Northern Hemisphere species of swan all have pure white plumage, but the Southern Hemisphere species are all patterned with various amounts of black. The Australian Black Swan (''Cygnus atratus'') is black all over except for the white flight feathers on its wings, and the South American Black-necked Swan has, as its name suggests, a black neck; finally, the Coscoroba Swan, also from southern South America, has black tips to the primary feathers. The legs of all swans are dark blackish grey, except for the two South American species, which have pink legs. Bill colour varies rather more; the three far northern species have black bills with varying amounts of yellow, and all the others varyingly patterned red and black. The Mute Swan and Black-necked Swan have a curious lump at the base of the bill on the upper mandible. ==Species of swan== Genus ''Cygnus'' *Whooper Swan, ''Cygnus cygnus'' breeds in Iceland and subarctic Europe and Asia, migrating to temperate Europe and Asia in winter. *Trumpeter Swan, ''Cygnus buccinator'' is a North American species very similar to the Whooper Swan (and sometimes treated as a race of it), which was hunted almost to extinction but has since recovered: it is one of the heaviest flight animals, at up to 17 kilograms (38 pounds). *Tundra Swan, ''Cygnus columbianus'' is a relatively small swan which has two major subspecies (sometimes treated as a distinct species); as the name suggests, it breeds on the Arctic tundra, further north than other swans. **Tundra Swan, ''Cygnus columbianus bewickii'' is the Eurasian form which migrates from Arctic Russia to western Europe and eastern Asia (China, Japan) in winter. The reserves of the Royal Society for the Protection of Birds and of the Wildfowl and Wetlands Trust in United Kingdom are important for Bewick's and Whooper Swans. **Tundra Swan, ''Cygnus columbianus columbianus'' is the North American race, which is sometimes considered a separate species from Bewick's swan. *Black Swan, ''Cygnus atratus'' of Australia, and introduced in New Zealand. The Black Swan is the official state emblem of Western Australia, and is also the symbol of the Sydney beachside suburb of Dee Why. *Black-necked Swan, ''Cygnus melanocoryphus'' of South America, formerly ''Sthenelides melanocorypha''. *Mute Swan, ''Cygnus olor'', is a common temperate Eurasian species, often semi-domesticated; descendants of domestic flocks are naturalized in the United States and elsewhere. Genus ''Coscoroba'' *Coscoroba Swan, ''Coscoroba coscoroba'', also of South America SwanSomething is wrong with the species and common names on this page. For instance why does a swan called the American whistling swan only live in Britain? The article text and the chart at the bottom of the page do not agree, I think. Surely this is a mistake. User:Rmhermen 16:32 Mar 5, 2003 (UTC) ---- What species name is used for the tundra swan by those who consider it a separate species from Bewick's swan? User:Vicki Rosenzweig :Those who consider them to be separate species call them ''C. columbianus'' and ''C. bewickii'' respectively. This was explained in my earlier pedantic and hard-to-read version (http://www.wikipedia.org/w/wiki.phtml?title=Swan&oldid=766947) but was lost in Jimfbleak's otherwise successful improvement. -- User:Heron ---- I think my picture looks nicer than the one placed in the table, does anyone else agrreed it should be resized and changed? Also my picture is a picture for wikipedia, not a public domain image from anotehr site. -fonzy :You don't need anyone's permission to change it, although its nice that you've taken the trouble to ask. The only thing I would say is that 250 pixel width has become semi-standard for pictures in tables, with a link to a larger version if desired. :After all, your picture may also be replaced or editted at some future date-go for it. User:Jimfbleak 05:36 May 13, 2003 (UTC) ::I didn't spot your pic (honestly I didn't!) when I put mine into the taxobox or I would have chosen one which looked less like yours. ::I can't understand why you say my pic is "a public domain image from another site". It certainly is not from another site, I took the pic myself and it doesn't appear anyewhere else on the internet. I went over to the local park specially to take pictures for Wikipedia. ::My method is that I always give a larger version for anyone who wants to print the pic or to use it in a project and I make it 250 pixels wide to fit the "standard" taxobox size. ::User:Arpingstone 21:53 3 Jul 2003 (UTC) == Dining on swan == ".. roast swan is a traditional item at celebratory dinners in certain Oxbridge colleges.. " ::Erm... this is Peterhouse in Porterhouse Blue surely and not a reality - I don't think that you can actually dine on Swan m so unless someone provides firm evidence I think this should be removed. User:IVoteTurkey 15:44, 13 Dec 2004 (UTC) ==swan ownership== reverted recent edit since no swans other than Mute Swan are owned by the the crown, and only some of those. == Nonsense etymology == Taken out of the article: :The word "swan" comes to us, unchanged, from the ancient Anglo-Saxon language of England. So do many hundreds of words... :It is possible that the word ''swan'' has its ultimate root even earlier, arising in part from the Celtic language survival ''Gwen'' (meaning "white"). Er, no... compare German ''Schwan'', Dutch ''zwaan'' and Norse ''svanr''. No need for any Caltic survival whatsoever.
