HUMPBACK WHALES
Before the era of commercial whaling, an estimated 15,000 humpback
whales
roamed the North Pacific. Today, approximately 500 of these majestic
creatures summer in Southeast Alaska waters. Reaching lengths of up to
55
feet (16.7m), with the average length being 42 feet (12.7m), an adult
humpback is about the size of a typical charter boat! How do you know
the
whale you've spotted off the bow of the Caledonia is a humpback?
One
distinguishing features is the whale's uncommonly long flippers. Also,
look for a black and white pattern on the ventral side of the animal
when
it lifts its fluke to dive. All whales make sounds but the humpback
is
known to have the most diverse "language" employing many sounds
including
grunts and chortles.
BROWN BEAR
The term "brown bear" is often used interchangeably with the word
grizzly
to refer to members of the species Ursus arctos, a type of bear found
throughout coastal and inland Alaska. Brown bears, which range in
color
from dark brown to blond, have a prominent shoulder hump which easily
distinguishes from their cousin the black bear. Protein rich salmon
are an
important part of their summer diet and they can often be seen feeding
in
inter tidal zones or by streams where salmon are spawning. The average
weight of an adult male is 500-900 pounds. For safe viewing of bears,
a
respectful distance and a respectful attitude are advisable. Give them
at
least 100 yards if not more. Be especially cautious when encountering
a
female with offspring as she is liable to be very protective of her
young.
