The Mute Swan Cygnus olor is a species of swan, and thus a member of the waterfowl family Anatidae. It is native to much of Europe and Asia, and as a rare winter visitor the far north of Africa. It is also an introduced species in North America, Australasia and southern Africa. The name `mute` derives from it being less vocal than other swan species. It is recognizable by its pronounced knob atop the bill. Head details.
