The mute swan is a very large white waterbird.
It has a long S-shaped neck and an orange bill with black at
the base of it. Flies with its neck extended and regular
slow wing beats. Mute swans breed in the
British Isles, north central Europe and north central
Asia. Although strikingly elegant, mute
swans (Cygnus olor) are one of the bay's most harmful
species, edging out native waterfowl and destroying aquatic
vegetation. This article will explore the many exciting
aspects of the mute swans species from their population,
behavior to their physical appearance.
The population trend for this species in the United
States, as judged by the Breeding Bird Survey, has been
steadily upward. Population growth and range expansion of
this species has increased the number of swan-related
problems for people and native wildlife. Often, people
mistake a large number of swans seen together as indication
of a rapid increase in population. Owing to this assertive
behavior, mute swans are also able to establish populations
in new areas fairly quickly.
Mute swans can be distinguished by their unique
behaviors. They establish strong bonds when they pair up.
Mute swans feed almost exclusively on SAV (submerged aquatic
vegetarian) like widgeon grass and redhead grass. Mute
swans occupy and defend relatively large territories of
wetland habitat during nesting, brood rearing and foraging,
and thus compete with native birds for habitat. Mute swans
fly at a rate of 50 to 55 miles per hour and don't usually
breed before the age of three years. Mute Swans have been
known to live for over 25 years, but most only survive to 5
or 6 years old. The nesting period for mute swans begins in
late March to April.
Mute swans are large birds, measuring 144 to 158 cm.
The wingspan is 2 to 2.5 meters. The two sexes are alike in
appearance, except that males are generally larger than
females. The plumage is white. They are best distinguished
from North American swans by the knob at the base of the
upper bill, and the color of the bill itself, which is
orange, with the tip and base colored black. The head and
neck may sometimes be stained brown from water and mud
containing iron. Mute Swans
are one of the world’s largest flying birds, weighing
twenty-five to forty pounds (10 to 18 kg).
As
you can probably tell now, not only mute swans are one of
the biggest birds but their unparalleled characteristics
have attracted many people to breed them.
