The Mute Swan is an Old World swan that have become established in parts of the North East. It is a familiar sight in urban ponds and lakes of Europe.
It is actually native to the fresh water marshes and lakes of central Asia.
They are relative tame here in America and Brittan, however in their native area, they are unapproachable.
Their domestication goes back to the 12th century in Brittan. They were also domesticated by the Greeks and Romans.
The Asian populations are in decline as habitats are lost.
