Eagle Cries
The Bald Eagle
The Bald Eagle is just one of 150 bird species known to inhabit
the lands and shores of Vancouver Island. The Bald Eagle,
however, is not really bald; it actually has white feathers on its head,
neck, and tail. Bald is a derivation of
bald, and old English word
meaning white. So the eagle was named for it’s white feathers instead
for a lack of feathers.
Eagles are numerous and these majestic birds are easily viewed
throughout the area. The best viewing experiences are generally
along the western shores of Quadra Island in the many trees
that provide the ideal perch for the daily offerings that come with
the tide. Campbell River offers many eco wilderness tours where
you can seek out eagles and other wildlife in their natural wilderness
settings.
To the local First Nations in this region, the Kwakwala word for Eagle
is Kwikw. In ceremonies, Eagle down is used for blessing the Big
House or blessing a totem pole. It also is used for a peace dance
called Kla'sa'lah. In this dance the Eagle down is put on top of the
headdress. It is also believed that the Eagle has supernatural powers;
he is a leader of the wild beings of the woods, a watchman, a guider
and a protector of predators.
An estimate of the mid-winter population for the province of BC
is between 20,000 and 30,000 birds. On the coast, Bald Eagles make
their nest near the seashore, in estuaries, and at the mouths of rivers
and creeks. Nests are usually placed in coniferous tree crotches, on
branches next to the trunk, occasionally on branches a short distance
from the trunk, or near the crown of the tree. These nests are very
large, sometimes measuring up to six feet in width and weighing
hundreds of pounds. Bald Eagles may use the same nest year
after year, adding more twigs and branches each time. One nest was
found that had been used for 34 years and weighed over two tons!
Most nest sites have an unobstructed view of the surrounding area,
and a food source is usually nearby. Along the coast, most nests are
within 100 m of the shore.
The Bald Eagle is primarily a scavenger rather than a predator,
and subsists on fish including spawning salmon, "herring balls"
and surface-feeding fishes. Bald Eagles are a very important part
of the environment. By eating dead animal matter, they help with
nature’ clean-up process. Bald Eagles are also hunters so they keep
animal populations strong. They do this by killing weak, old, and slower
animals, leaving only the healthiest to survive.
A heavy yellow bill, large powerful talons and white head and tail
feathers that take about 4 years to attain, characterizes a mature
eagle. Adult males have a body length of 75-85 cm (2-3 feet) and a
wingspan of 180-213 cm. (6-7 feet). The female is slightly larger.
The Bald Eagle can fly 20 to 40 mph in normal flight and can dive
at speeds over 100 mph. The call of the eagle is distinguishable
by squeaky cackling with thin squeals. Life span is not known but it
is estimated to be approximately 50 years.
