They evolved on the tundra plains south of the ice sheets in Eurasia and are equally at home on the Arctic barren grounds, the prairie and foothills grasslands, or the thick temperate rainforests of coastal British Columbia and Alaska. A bear may occupy a home range that overlaps the territories of other bears and simply avoid them most of the time. Male bears tend to range over larger territories, maintaining home ranges that overlap the smaller home ranges of several females.
They build their habitats in mountainous woodlands in Europe. Brown bears primarily reside in the alpine meadows across Central Asia due to the fact that human disturbance is minimal in this part of the world.
Bears inhabiting in Siberia, seem to live in denser pine forests. Black bears are predominantly found in misxed forests, deciduous forests, thornbrush forests, and deserts. They are not found at altitudes of more than 12, ft 3, m. Black bears typically reside around 11, feet 3, metres and will descend in winter to a height of 4, feet 1, meters and they come to a sea level in Japan.
These bears inhabit along the southeastern Iran, Pakistan, Myanmar, foothills of India, and Afghanistan. They are not found in Malaysia and east-central China. The Asian black bears inhabit across northeastern China in the conifer forests of temperate and cold regions. In China, there are two recognized black bear species; U.
There are around Asian black bears living in the province of Liaoning. The American black bears inhabit all throughout the range of North American forested regions.
Currently, they are classified as largely restricted to sparsely settled and forested regions. American black bears are the inhabitants of native Canadian range, with some species found in the farmlands of Manitoba, Alberta, and Saskatchewan.
There are around , to , species in seven Canadian provinces according to the survey of The average weight of male polar bears in Ontario is about kg lbs. Adult female bears are smaller and average around kg lbs ; their peak weights do not usually exceed kg lbs.

This includes small mammals, birds, fish, molluscs and carcasses. They also feed on grasses, fruits, berries, seeds, insects and honey. In autumn they fatten up for the winter by feeding on nuts. In northern climates they hibernate. In southern climates they do not hibernate. Photos courtesy of Wildlife S. The bears are an endangered species, listed as Vulnerable, and it is illegal to kill them.
The Andean bear is the last remaining short-faced bear subfamily Tremarctinae and the closest living relative to the Florida spectacled bear and short-faced bears of the Middle Pleistocene to Late Pleistocene age.
Spectacled bears are the only surviving species of bear native to South America, and the only surviving member of the subfamily Tremarctinae. The Spectacled bear is a mid-sized species of bear. Overall its fur is blackish in color, though bears may vary from jet black to dark brown and to even a reddish hue.
Bears can also create a den by digging a hole into a hillside or under tree roots. Because bears are mammals, they give birth to live young. Baby bears are called cubs. Cubs are completely defenseless when they are born and rely on their mothers for food and protection. Sun bear cubs have no hair and cannot smell or hear when they are born. Their mother will often stand upright like a human and carry their cubs in their paws or mouth, according to the San Diego Zoo.
Cubs can be smaller than teddy bears. Brown bears weigh as little as 16 to 25 ounces to grams when they are born. Newborn sun bears are even smaller and can weigh 7 to 12 ounces to g. The taxonomy of bears, according to the Integrated Taxonomic Information System, is:. Six of the eight bear species all except brown bears and American black bears are endangered or vulnerable, according to the International Union for Conservation of Nature IUCN.
The giant panda is the most endangered bear. It is estimated that only 1, to 2, remain alive in the wild, according to the IUCN.
Polar bears are also endangered.
