Trumpeter Swan – Description

Standing up to four feet high, and with a wingspan of seven feet or more, the pure white Trumpeter Swan is a spectacular bird. Its name comes from the bird’s resonant, trumpet-like call.

Trumpeters are often confused with Mute Swans (Cygnus olor), which were introduced by European immigrants and are the swans typically featured in artwork and folklore. Unlike the black-billed Trumpeter, the Mute Swan has an orange bill and males have a prominent black knob extending from the base of the bill to the forehead.
