Mute
Swan
Cygnus olor
Here
is the swan of legend, with gracefully curved neck,
and wings arched over the back in display. The Mute
Swan is one of three swan species in British Columbia,
but unlike the Tundra Swan and the Trumpeter Swan, it
has been introduced to North America. The species is
native to Eurasia; it is said that all the Mute Swans
in North America can trace their lineage to the Royal
Swannery in England.
The
species survives in a feral state only on southern Vancouver
Island; Mute Swans elsewhere in the province are either
captive birds, or escapes. Although charismatically
beautiful, they can have rather nasty manners towards
other native waterfowl. A male Mute Swan was removed
from the Swan Lake Nature Sanctuary in Victoria because
of his aggressiveness. The lake, incidentally, was named
not for the birds, but for an early surveyor named James
Swan.
The
Mute Swan almost lives up to its name; it produces little
more than hissing sounds. Its wild cousins are more
vocal, with the Tundra Swan giving a high whistling
call, and the Trumpeter Swan a rich, sonorous bugling.
Both of these species hold their necks much straighter,
and neither has the distinctive pink knob on the bill
of the Mute Swan.
