Mute Swan (Cygnus olor)
The Mute Swan was introduced in the 1800's from its native Europe and Asia. They have
established themselves and are now found on rivers, ponds, and lakes throughout our area.
There are two species of Swans in our area. The Tundra Swan, also called the Whistling Swan,
breeds in the tundra of northern North America, but many spend the winter in the relative warmth of
the mid-Atlantic states. The Mute Swan can be distinguished from the native Tundra Swan by it's
bright orange bill and S-shaped curve in the neck when swimming. The Tundra Swan and the Mute
Swan can also be easily distinguished by their calls. The Tundra Swan makes a sort of high pitched
honking "woo-woo" while the Mute Swan while the Mute Swan makes a raspy "heorrr".
