Habitat
|
Bears
utilize a number of habitat types including open areas,
thick bursh, and hardwood forests. Their den consists
of dense thickets, small caves, rock overhangs, and of
hollowed out areas they dig under tree roots. In the piedmont
(foothills) areas of Georgia, bears are frequently found
near beaver swamps. |

Ecological
Niche
|
Black
bears are classified as a large carnivore, however, they
are actually vegetarians. On occasion, they will eat some
of a deer they find dead, but they rarely kill anything
themselves. They consume large quantities of acorns, berries,
fruits, nuts, mushrooms, grasses and green leaves. Environmentally
unaware humans are their only predator. |

Life
Cycle
|
Young
are born in mid-winter while the mother is hibernating.
The first 6 to 8 weeks are spent in the den nursing while
the mother sleeps. They weigh only 7 to 10 ounces at birth.
Their eyes open 25 to 30 days of age. They will stay with
their mother for a year or more. Bears first mate at 3
1/2 years. Most wild bears live 12 to 15 years, but in
captivity some have reached 30 years of age. |

Behavior
and physical adaptations
|
They
are primarily nocturnal but occasionally are out at midday.
Though not true hibernators, black bears will sleep for
long periods and wake up sporadically. Their eyesight
is poor, their hearing is good, and their sense of smell
is excellent. They have long claws and powerful short
legs for digging. In spite of their weight and short legs,
a bear can outrun a horse for about 300 to 400 yards.
