Urban species #058: Mute swan Cygnus olor

The swan is symbolic of elegance, grace, and wealth. Mute swans have been introduced to many North American locations, in the hope that this bird's presence would bestow these qualities. In Boston, the symbolism is further emphasized by the famous Swan Boats. A pair of mute swans shares the public garden lagoon with the boats in summer. In 2005 the pair was found to be two individuals, that while they may have been pair bonded, were both female.

In Europe, where mute swans are native, they were hunted as game birds. They were domesticated for the table, which helped keep the wild population from being hunted to extinction. It also helped make the sight of swans on the lake of an estate something to be desired and expected. The beauty of the bird has since eclipsed its value as a food animal.

Mute swans are notable for being very large birds and for showing violent territorial behavior. They are on the very short list of flighted birds that can seriously injure a human, and occasionally do. The long neck of a swan allows it to feed on aquatic plants out of the reach of other dabbling birds. This feeding method can disturb the ecology of a lake or pond by uprooting the plants and muddying the water. Massachusetts Audubon Society ornithologist Elissa Landre believes that mute swans have the potential to become an ecological management problem much as Canada geese have.



Mute swans can be distinguished from native North American swans by the large knob at the base of the bill, and the bright orange color of the bill itself.



The mute swan arches its wings over its back in an aggressive display.



As its name implies, it does not trumpet or honk; It does hiss loudly, like a goose.

They had a home video on the news here about a year ago of an Egyptian swan goose chasing off a bob cat!
