Mute Swan Identification

The Four Keys to ID

  • Size & Shape

    Mute Swans are very large waterfowl. They have heavy bodies, short legs, and a long, slender neck habitually held in a graceful S. The large, flat bill has a bulging knob at the base.

    Relative Size

    Among the largest of waterfowl: more than double the size of a Snow Goose and about the same size as a Trumpeter Swan.
