Black bear (Ursus Americanus) is one bear subspecies are found inhabiting a variety of forest habitats across North America. Black bear is a sub-species of bears with the highest population number even when compared with the number of sub-species of bear in the world. Black bear is also one of only two sub-species of bears that are not listed by the IUCN as endangered. Conservation effort goes well make the black bear population growth with a healthy walk.

Despite their name is the black bear, black bear hair color can vary from black to dark red or brown and even in certain areas, the color black bears could be light brown. Black bears have short, thick fur covering their bodies. They also have a pointed snout, small eyes and ears are larger and more pointed than their relatives that the brown bear. There are some striking differences between black bears and brown bears. Black bears have shoulders and legs and claws are shorter than the brown bear. Short legs and claws that they have made the black bears become much more agile climber than brown bears. So that when they meet, black bears can climb trees faster to avoid conflict with the brown bear. Like all other sub-species of bears, black bears have an excellent sense of smell that is used to detect food. Hearing and vision while black bears are underdeveloped, because ears and their eyes are relatively small.

Black bears are solitary animals (live menyediri) and nocturnal (active at night). Black bears spend most of their time looking for food each day to ensure that they build sufficient fat reserves for the winter. When winter comes, black bears will go to nest, usually located under a tree hollow, where they will hibernate (winter sleep) for months. Time hibernating black bears varies. Black bears that live in the north have a longer hibernation up to 8 months. While the black bears that live in its South section has a relatively short period of hibernation.

Black bear male and female will meet for mating in summer. After a gestation period which lasts for about 7 months, a female black bear will give birth to between one and five children in late winter in the nest. Black bear cubs will stay with their female parent until they are nearly two years and have learned the skills they need to survive on their own. After quite mature and independent, black bear children will perform their own travel.

Although technically classified as carnivores, mostly black bears diet comes from plants. Between 75% and 95% of their diet is vegetarian (depending on the food available at different locations). Black bears usually eat fruits, nuts, grasses, roots and tubers. And to supplement their diet, black bears eat small animals such as insects and rodents. Black bears are also known to young deer hunting, eating carcasses and also be able to catch fish in the river. Black bears spend on average 12 hours a day to eat to build up fat reserves for the winter.

Black bears do not actually have the predators in their environment. However, black bears are common in conflict with grizzly bears alive are much more aggressive in some areas. Black bears often escape by climbing a tree to escape from the conflict with a grizzly bear. Black bear cub who is weak be hunted foxes, and bird meat eaters. Although black bears and humans tend to have a relatively peaceful relationship, they are often persecuted by farmers who fear their livestock being eaten by black bears. More black bear populations are threatened by poaching and loss of their natural habitat due to deforestation.
