Mute Swan

 

(Cygnus olor), a bird of the order Anseriformes. The body measures about 1.5 m in length. The plumage of the adult is white, and of the young, gray. The bill is red, except for the knob at the base and the tip, which are black. The mute swan is found sporadically in Europe, Asia Minor, Middle Asia, and Central Asia. In the USSR it is found in Estonia and Lithuania, along the lower courses of the Danube, Dnestr, and Volga rivers, in southwestern Siberia, and in Kazakhstan, Middle Asia, and Transbaikalia. The mute swan inhabits large lakes with reed thickets. It winters on the Mediterranean, Black, and Caspian seas and in Middle Asia. The clutch contains seven to nine eggs, which are incubated for 35 days. The diet consists of aquatic vegetation. The mute swan is a protected species and hunting is prohibited by law. Domesticated mute swans are found in parks.
