They are often found in mountainous areas and forests. The black bear lives in North America. The brown bear is found in North America, Europe, and Asia. The Asiatic black bear and the sloth bear live in parts of Asia. The world’s far northern regions called the Arctic are home to the polar bear.Most bears live in northern regions with a mild or cold climate. However, the spectacled bear is found in the Andes Mountains of South America. The sloth bear of India and Sri Lanka lives in hot or warm regions.Physical FeaturesBears range in height from about 3 to 10 feet (1 to 3 meters). The sun bear is the smallest species. A kind of Alaskan brown bear called the Kodiak bear is the largest bear. It may weigh 1,720 pounds (780 kilograms). Some polar bears are almost that big.Most bears are mainly brown, red-brown, or black. Some have white markings on the chest or face. The type called the black bear is sometimes actually brown, blue-gray, or even white. The polar bear's white fur helps it blend in with the Arctic ice and snow.Bears have broad heads, large bodies, and short legs and tails. They have poor eyesight but an excellent sense of smell. Most kinds are good at climbing trees and at swimmingBehaviorBears are carnivores, or meat eaters. For example, the polar bear eats seals, walrus, and fish. However, other bears eat a large amount of plants as well as animals. They may eat roots, seeds, berries, and nuts, plus insects, fish, and deer.In the autumn most bears eat a lot to put on extra fat. They then sleep through most of the winter. This is similar to a very deep resting state called hibernation. But bears are not true hibernators. Their body temperature, heartbeat rate, and breathing rate do not drop much lower than normal.ReproductionAdult bears tend to live alone except during the mating season. A female bear gives birth to one to four cubs, or babies, at a time. At first the cubs are tiny, hairless, and helpless. They drink their mother’s milk for about two months. The cubs stay with their mother for 18 months or more. North American Black BearThe North American black bear (Ursus Americanus) is black, bluish-black, brown, white (Kermode or Spirit bear) in color. Their the smallest bear species that you’d find in North America. It’s also the most common bear in the region.American black bears have a variety of colors despite their name. Most have black fur, but some are entirely brown or brown & black. Spectacled bearOnly found in South American in the Andes mountains. They are the only species of bears alive in South America.The Spectacled bear is a mid-sized species of bear, and only Baird’s and South American Tapirs are heavier. Their fur is usually jet black to dark brown and can sometimes even have a reddish hue.On some of them, there exists notable beige-colored fur across the face and upper chest, though not all Spectacled bears have “spectacle” markings. Male of this species can weigh between 220 – 440 lb and females 77 – 181 lb. These types of bears have a more rounded face with a relatively short and broad snout when compared to other bear species. Panda BearThe panda bear species are white and black bears that are native to Asia. Pandas have large, characteristic black patches around their eyes, over their ears, and across their round bodies. Most males pandas weigh around 250 lbs while the females are around 220 lbs. Their diet is 99% bamboo, and they eat about 50 pounds of it every day.Baby pandas are tiny when they are born, weighing about 120 grams. They are bout 1/900th the size of its mother. The babies are also born pink, hairless, and blind. Pandas do not hibernate. Instead, they move to higher elevations (in the summer) to stay cool and travel to lower elevated (in the winter) areas to keep warm. Sloth BearThe sloth bear (Melursus ursinus) is an insect-hunting bear that feeds on termites, ants, and even honeybees. English naturalist George Shaw, in 1791, named it Bradypus ursinus (sloth bear), believing it to be related to sloths.They have large lips and a long tongue (perfect for sucking up ants and termites). They also have well-developed hook-like claws that enable them to climb trees and dig for termites and ants.A sloth bear will also eat fruits such as mangoes and figs and are even known to eat flowers. On the sloth bear’s chest is a cream-colored, ‘u’ or ‘v’ shaped patch of fur. Although, it’s not present on all sloth bears. Sun BearIf you ever wanted to know what is the smallest bear, then, the sun bear (Ursus malayanus) is the smallest bear species in existence today. These types of bears have short black/dark brown water-repellent fur, with a yellow crescent on their chest.They have similar features to the sloth bear in that they also have flexible snouts and extremely long tongues, which they use for extracting termites from nests. Polar BearThe Ursus Maritimus is commonly known as the polar bear and its one of the largest bear species in the world. Adult male polar bears usually can reach up to 1100 pounds while females typically grow to 660 pounds.These large-sized bears live in the Arctic Circle, where they hunt mainly seals. They can also live in Canada, Alaska (US), Greenland, Russia, and Norway.Polar bears are the largest land carnivores currently in existence, the only other bear to rival it in size is the Kodiak bear.Polar bears also eat a variety of other animals, including muskox, reindeer, birds, eggs, rodents, crabs, other crustaceans, and even other polar bears. Asian Black BearThe Asian black bear (Ursus thibetanus), also known as the moon bear, Himalayan black bear, and the white-chested bear, is a medium-sized bear species native to Asia. Asian black bears have long black fur and a white patch of fur on their chest that’s often crescent-shaped.These types of bears have a varied diet, although mostly carnivorous, that includes small mammals, birds, fish, mollusks, and carcasses as well as grass, fruits, berries, seeds, insects, and honey.The ones that live in northern climates are known to hibernate; however, those in southern climates they do not hibernate. Brown Bear (Grizzly Bears)The brown bear or grizzly bear (Ursus Arctos) is one of the most omnivorous types of animals in the world and consumes a wide variety of foods of any bear.These kinds of bears inhabit areas of North America and can be found in parts of Asia and Russia as well. These types of bears also vary in colors and sizes. Their fur can be almost black, brown to very light brown or blonde in color.The brown bear’s size varies considerably depending on geographic location and general food availability. The giant brown bears, the “Big Browns,” live along the coast of Alaska and Russia, growing to enormous sizes rivaling that of the Polar Bear. The bears of the North American Rocky Mountains (Grizzly Bear) and the mountains of Europe tend to be much smaller in size.
