The Mute Swan is a white graceful swan with a black-knobbed orange bill tilting to the ground. It often swims with an S-curve in the neck. The immature young birds have black at the base of a pinkish bill. It was introduced from Europe. It has a range around the Great Lakes and is expanding to the Northeast coast of the United States. It has a habitat at fresh and salt-water ponds, coastal lagoons, and salt bays. The diet is mostly plant material consisting of seeds, stems, leaves, pondweeds, and algae.
One of the areas where the Mute Swan was photographed was at the Vernon Marsh Wildlife Area near Mukwonago, Wisconsin.
