A variety of interactions,
good and bad, has been taking place between bears and humans
for thousands of years. Here is a sample.

Being on Your Best Bear Behavior
Being able to view bears in the wild is an awesome experience
but it can also be a dangerous one. It is difficult to predict
exactly how a bear will react to you in an encounter but the
most important thing is to stay calm and don't run away. Running
only seems to incite a bear and bears can run much faster than
you can. When in bear country, always travel in a group. There
is safety in numbers and more noise too, thereby alerting bears
to your presence.
Bears are naturally shy of people so they will usually leave
if given the opportunity. Always choose open trails during the
day so the bear sees you first and avoids the encounter. If
you see a bear in the distance, turn back, make a wide detour
around it or wait until the bear moves away.
Face to face confrontations may be impossible to avoid if the
bear is attracted by human food or garbage or it is a surprise
encounter. Remember that black bears tend to be bluffers, snorting,
swatting the ground and acting aggressive but rarely charging.
Stand your ground but try to avoid direct eye contact as a bear
may interpret this as an aggressive signal.
If you come upon a bear in a very close encounter, back away
slowly, talking calmly. Move toward safety (a car, a building,
etc.) If the bear is still interested in you, drop some item
(but not food) to distract its attention.
Beware of a bear growling or roaring with its ears laid back.
This means that the bear is agitated and may be about to charge.
When this happens your best hope it to drop to the ground on
your stomach, cover your neck and head with your arms and lie
as still as possible. If you are wearing a backpack, leave it
on as it may afford you some protection. Remain as quiet as
possible. The bear views you as a threat and "playing dead"
can work. When the bear moves away, remain on the ground for
an extended period of time, the bear may have just moved off
to watch. Wait until you are sure the bear has moved on before
getting up.
Be calm, be alert and enjoy the fact that we still do share
many wild spaces with bears.

Brown
bear (Ursus arctos)
A View to a Bear
One of the best places to see bears and learn more about them
is at your local zoo. Modern zoos are working very hard to help
save endangered bear species, both with captive breeding programs
and in habitat preservation projects around the world. Over
the past decade zoos have been and are continuing to work very
hard on creating naturalistic exhibits for their bears, exhibits
that not only teach people on how bears fit in their environment
but also to provide natural and stimulating enrichment for bears
that live there.
For the adventurer, many opportunities exist in the United States
to see bears in the wild, both as independent hikers and as
part of naturalist tourist groups. Check with your state and
national park authorities for areas known for bear sightings,
check with your local zoo for organized trips or call a travel
agent specializing in nature tours.
Some sites for brown bear watching include:
Several U.S national parks including: Glacier
in Montana, Great Smoky Mountains in Tennessee and Yellowstone
in Wyoming, and Katmai National Park in Alaska
Mc Neil River Sanctuary, Alaska (many naturalists
and photographers rank this as one of the world's best wildlife
viewing areas).
For polar bear watching
visit join an organized tour to:
Denali National Park in Alaska or Churchill, Canada.

The Man Eaters
Bears have provoked many emotions in man throughout history,
fear being the strongest. And as is usually the case, it is
a fear based on misconceptions. Bears are not vicious man eaters;
in fact, most bears eat little meat in their diet at any time
so stalking and consuming humans makes little sense. And although
most bears are strong enough to injure or even kill humans,
they are usually timid and retreat at the first sound of human
activity. They only attack if they feel threatened or are protecting
cubs. Most bears will go out of their way to avoid human contact.
The noted exception to this would be a hungry polar bear, the
most carnivorous of all bears has been known to hunt humans
when no other food source is available.
In contemporary news stories, reports of bear attacks almost
always involve campers who have left food in or near their tent
or back pack. One particular incident saw a man lose two fingers
to a bear he was actually feeding out of his hand. The bear
simply couldn't differentiate where the food item ended and
the hand began. Other attacks have been precipitated by campers
hand-feeding bears and then running out of food. When the tidbits
stopped, the angry bear demanded more in the only way it knew
how. The myth of the sly, ravenous bear stalking the unwitting
human is precisely that, a myth.

Bears: The Sacred Symbol
To the Greeks and Romans the bear was the figure of motherly
compassion, a belief they derived from observing the female
bear's unique care given to her tiny cubs. Ancient writers believed
that the mother bear continually licked her little cub until
it took shape. This was considered to be the very essence of
creation, and as a result the Greeks and Romans referred to
the bear only in the feminine gender. In the classical world
of 40,000 years ago, the bear appeared as a goddess wearing
a bear mask, the very symbol of the great mother of all creation.
Throughout history and around the world bears have figured in
man's mythology. Their strength, their maternal care, their
ability to stand human-like on two feet, their understanding
of the passing seasons in their natural world, their amazing
ability to hibernate, have all contributed to the bear mythos
in cults and religions throughout human culture.
Native Americans have long respected the bear, considering it
magically powerful spirit. The medicine man or shaman often
impersonated the bear, wearing necklaces of teeth and claws,
donning a cloak of bear skin and invoking the bear spirit for
success in many of the tribe's endeavors.
One only has to look at today's sport section in the local newspaper
to see that modern man still considers the bear a powerful spirit,
worthy of invoking its magical characteristics for one's favorite
team.

About Paddington, Pooh, Teddy and Friends
The nurturing side of bears, combined with their soft, furry
appearance, their inquisitive, playful nature and their ability
to stand on two legs have long made bears a favorite in children's
literature. A brief list of personable bears known to children
would certainly include
Winnie The Pooh, created by A.A. Milne
Paddington Bear, by Michael Bond
The Jungle Book's Baloo the Bear, written by
Rudyard Kipling
Goldilocks and The Three Bears, by Robert Southey
The Berenstein Bears, by Jan and Stan Berenstain
Little Bear, created by Else Holmelund Minarik
Smokey Bear, a real black bear cub rescued from a forest fire
and nursed back to health became an important "spokesperson"
for the United States Forest Service.
One of the staples of every nursery is a teddy bear. This beloved
symbol of childhood and innocence actually came to us in the
early 1900's, when President Teddy Roosevelt, an ardent hunter
and conservationist, refused to shoot and kill a black bear
that was tied to a tree. The press loved this example of the
President's compassion for nature, playing up the story and
soon a New York toy manufacturer created a stuffed bear named
Teddy with the President's permission. The teddy bear was sold
as a Christmas novelty more than 90 years ago and today is probably
the most popular stuffed animal in the world. |
Of Bears and Beakers
Researchers studying hibernating bears have found that instead
of disposing of their metabolic waste, bears recycle it. For
example, denning bears normally turn potentially toxic nitrogen
compounds into protein. Bears that cannot do this die from uremia,
a condition in which nitrogenous wastes normally excreted by
the kidneys remain in the blood. Once the mechanism by which
bears are able to do this can be isolated it may have some very
significant implications with regards to treatment of kidney
failure in humans.
Data from studies on bears has already been instrumental in
defining a diet program to reduce the frequency of dialysis
for anephric humans awaiting kidney transplantation. This program
has also been successful for people on hemodialysis who wish
to dialyze less often.
Another human illness where bears may provide an answer is osteoporosis.
Sufferers of osteoporosis slough off tissue faster than its
made resulting in a build up of calcium in the bloodstream.
If excess calcium in the bloodstream is not excreted it could
be lethal. Mammals, including humans, which maintain non-weight
bearing positions for a long time suffer from osteoporosis (a
thinning and weakening of bone) except for bears! Black Bears
which lie in dens too small for weight-bearing positions should
suffer from osteoporosis just like human astronauts and the
elderly or bedridden because bones support almost no weight.
If hibernating bears do lose bone, they would have to prevent
the calcium in their blood rising too high. Researchers have
found that the Black Bear's blood levels of calcium and phosphorous
(both used to make bone) remain constant throughout summer and
winter because the bear's bone metabolism operates like that
of an active animal. Researchers are now trying to isolate a
regulatory substance circulating in the blood which is responsible
for maintaining bone mass. This may eventually enable physicians
to prevent osteoporosis in humans.
Researchers believe that there is a hormone produced by part
of a bear's brain which controls temperature as well as appetite.
If this is true and the hormone can be isolated then potentially
it could be administered to patients with kidney problems, obesity
or anorexia nervosa.
If the bear's hibernation induction trigger can be isolated,
it could be used to slow metabolism and reduce head swelling
in severe trauma cases, slow and cool the body during surgery,
extend the viability of organs waiting to be transplanted and
prevent fibrillation (wild, uncontrolled contractions of the
heart) in heart surgery as it appears to in hibernating bears.
