Brown Bear
The brown bear is a mammal. It is distributed across northern Asia and North America. Brown Bear weighs between one hundred to seven hundred kg. It is mainly found in different areas of Russia, the United States, Alaska and Canada. The species primarily feeds on vegetable matter, including roots and fungi. Fish are a primary source of meat, and it will also kill small mammals on land. Larger mammals, such as deer, are taken only occasionally. Adult brown bears face no serious competition from other predators and can match wolf packs and large felines, often driving them off their kills. Brown bears have brown fur. The longer outer guard hairs of the brown bear are often tipped with white or silver. The length of their tail is about four to five inches. Brown bears liek all other bear, can stand up on their hind legs for extended periods of time. Their paws are about six inches in length. Their heads are large and round with a concave facial profile, a characteristic used to distinguish them from other bears. Their head-body length reaches about three meters. Their shoulder height is hundred to hundred and fifty cm. There are about two hundred thousand brown bears in the world. Their largest populations is in Russia which is about one hundred and twenty thousand. In United States they are thirty two thousands and twenty two thousands in Canada. Brown bears were once native to Asia, the Atlas Mountains in Africa, Europe and North America, but are now extinct in some areas and their populations have greatly decreased in other areas. They prefer semi-open country, usually in mountainous areas. The mating season takes place from late May through early July. Being serially monogamous, brown bears will remain with the same mate from several days to a couple of weeks. Females become sexually mature between the age of five to seven, while males will usually not mate until a few years later when they are large and strong enough to successfully compete with other males for mating rights. Adult bears are generally immune from predatory attacks from anything other than another bear. They are omnivores and feed on a variety of plant products, including berries, roots, and sprouts, fungi as well as meat products such as fish, insects, and small mammals.
