A native of northern and central Eurasia, the Mute Swan was introduced into North America to grace the ponds of parks and estates. Escaped individuals have established breeding populations in several areas, where their aggressive behavior threatens native waterfowl.
Not mute. Calls quiet and do not carry. A snorting "heorrr." Hisses aggressively. Wings make singing noise in flight.
