The Mute Swan (Cygnus olor) is a swan species native to Eurosiberia and North Africa. Outside of its native range, North America houses the largest population of the species after its introduction. The name ”mute” is in reference to the species being less vocal than other swans. Physically they have an all-white plumage with an orange beak that is bordered with black. The knob that sits on top of the beak is larger in males. They occupy large mounds that are built with waterside vegetation in shallow water on islands in the middle or at the edge of a lake. Their diet is largely agricultural crop plants like rapeseed and wheat.
