Grizzly
Bears
The Grizzly is one of two subspecies of Brown Bear occurring
in North America. The Grizzly may weigh from 350 lb. for a small female, to as
much as 700 lb. for a large male. This bear derives it’s name from it’s
coloration: the silver-tipped hair gives the animal a "grizzled"
appearance.
Intelligent and curious, grizzlies will investigate any new
object found in their environment. They are known to be fast learners. If a
bear finds part of a chocolate bar on a path, he may make repeated visits in
case another chocolate bar turns up. 75% of the Grizzly’s omnivorous diet is
derived from plants. They may become selective when food is abundant. During a
salmon run they may even abandon male fish to concentrate on catching females
in order to dine on the more nutritious salmon eggs.
Grizzlies, are strongly motivated during the summer months
to gain weight in preparation for the months of hibernation. (Not a true
hibernation, since they are easily awakened.) The instinct to hibernate is an
adaptation to life in places where winter conditions, such as reduced food
supplies and decreased mobility, may threaten survival. Newborns may weigh less
than l lb., and can increase their weight as much as 1000 times during their
30-year lifespan. Grizzlies are devoted mothers and cubs remain with them for
two to three years, during which time they learn their survival skills.
Though generally shy and peaceful, with an inclination to
stay away from humans, Grizzlies usually has been precipitated by the victim’s
lack of knowledge about bears. The Grizzly population has dwindled dramatically
since the first European settlers, eager to take control of the new land by
making it safe for themselves and their livestock, systematically decimated the
huge predators. They also turned a nice profit by selling the pelts, which were
extremely popular.
By 1900, the Grizzly had been eliminated from the Great
Plains and the surrounding hill country. Though the Grizzly is the California
State Animal and appears on our state flag, the last of these magnificent
creatures in California was killed in 1922. A few scattered populations
totalling only 800-900 bears still survive in the lower 48. The Grizzly is
currently classified as Endangered
