Appearance
Brown bears have coats in shades of blond, brown, black, or a combination of those colours; the long outer guard hairs are often tipped with white or silver, giving a "grizzled" appearance. Brown bears have a large hump of muscle over their shoulders which gives strength to the forelimbs for digging. The Brown Bear posesses tremendous power: a large specimen can break a bison's spine with one blow of its powerful forepaw. Their heads are large and round with a concave facial profile. In spite of their size, some have been clocked at speeds in excess of 35 miles per hour. Aside from their overwhelming strength and deceptive speed, Brown Bears are legendary for their physical stamina. They are capable of running at full speed for miles and miles at a time without stopping. The largest subpecies of the brown bear is the Kodiak bear and Alaskan Coastal bear. The largest Kodiak bear was captured on Kodiak island and brought to the Berlin zoo; it weighed 1200 kg, or over 2500 pounds, according to Great Bear Almanac by Garry Brown, though captive Kodiak bears sometimes weigh near 1500 kg in Autumn.

Habitat Once native to Asia, Africa, Europe and North America, [1] brown bears are now extinct in some areas and have had their numbers greatly reduced in others. They prefer semi-open country, usually in mountainous areas. The brown bear ranges from Alaska east through the Yukon and Northwest Territories, south through British Columbia and through the western half of Alberta. Isolated populations exist in northwestern Washington, northern Idaho, western Montana, and northwestern Wyoming.

- The subspecies U. arctos horribilis (the Grizzly Bear) is the common brown bear of continental North America;
- The subspecies U. arctos middendorffi (Kodiak bear) includes bears on the Alaskan islands of Kodiak Island, Afognak Island, and Shuyak Island.
- The range of the subspecies U. arctos nelsoni is in northern Mexico.
- In Asia, the Himalayan Brown Bear (U. arctos isabellinus) is found in the foothills of the Himalaya,
- and the Higuma or Hokkaido brown bear (U. arctos yesoensis) is found on the northern Japanese island of Hokkaido.
It is not known how long Ursus arctos has existed in North America. While there were certainly some there during the last part of the Ice Age, it is thought that the brown bear was not the dominant carnivore at the time. That role belonged to the far larger, taller, and stronger Giant Short Faced Bear, aka Bulldog Bear, which was almost certainly dominant when the two animals met. The Giant Short Faced Bear was adapted for fast running and meat from rather large animals was the main part of its diet, in contrast to the Grizzly or Brown Bear, which has teeth adapted to an omnivorous diet. The Giant Short Faced Bear, on average, weighed twice as much as the Grizzly, despite some exceptional Grizzly Bears in the later Old West that were recorded to have grown to 800 kilograms or so.

Ursus arctos also shared the land with the American Lion and Sabertooth, both at least a match for any Grizzly and both apparantly also dependent on large animals for food. But the Grizzly could eat plant food, insects, carrion, small animals of all kinds, and large mammals if needed, in contrast to the far more restricted food menu available to the giant cats and the Giant Short Faced Bear. This made the other big carnivores very vulnerable to starvation if the supply of available large mammals gave out, which eventually happened through hunting by humans.

Sabretooth (Victor Creed) is a comic book supervillain in the Marvel Comics universe, and an arch-enemy of Wolverine. ...
For whatever reason the Ice Age herbivorous megafauna became extinct; the Sabertooth, American Lion, and Short Faced Bear could no longer find enough suitable food, and faded into extinction, leaving the Brown Bear/Grizzly as top North American predator alongside wolves, the jaguar in the south, the black bear, and puma. It is not known precisely how long humans have lived in America, but the biggest human emigration there was about the time of the last Ice Age period, when the Paleo-Indians showed up. These people brought with them the Clovis Point and advanced hunting techniques. If these people were responsible for wiping out the Ice Age herbivore megafauna, it can be argued that Ursus arctos benefited in numbers and range by the extinction of the competing predators.

There are estimated to be about 200,000 brown bears in the world. The largest populations are in Russia, with 120,000, United States, with 32,500, and Canada with 21,750. Ninety-five percent of the population in the United States is in Alaska, though slowly in the West the bears seem to be repopulating along the Rockies and plains. In Europe, there are 14,000 brown bears in ten separate fragmented populations, from Spain to Russia and north into Scandinavia. They are extinct in the British Isles, extremely threatened or extirpated in France and in trouble over most of Central Europe.

Behaviour The brown bear is primarily nocturnal and, in the summer, puts on up to 180 kg (400 pounds) of fat, on which it relies to make it through winter, when it becomes very lethargic. Although they are not true hibernators and can be woken easily, they like to den in a protected spot such as a cave, crevice, or hollow log during the winter months. A nocturnal animal is one that sleeps during the day and is active at night - the opposite of the human (diurnal) schedule. ...

They are omnivores and feed on a variety of plant parts, including berries, roots, and sprouts; fungi; and fish, insects, small mammals, and unattended picnic baskets. Contrary to popular mythology, brown bears are not particularly carnivorous; they derive up to three-fourths of their dietary food energy from vegetable matter. Interestingly, bears eat an enormous number of moths during the summer (sometimes as many as 20,000 to 40,000 in a day) and may derive up to a third of their food energy from these insects. They also occasionally prey on deer (Odocoeilus spp.; Dama spp., Capreolus spp.), red deer (Cervus elaphus spp., or American elk), moose (Alces spp.) and wild boar (Sus scrofa). Omnivores are organisms that consume both plants and animals. ...

Normally a solitary animal, the brown bear congregates alongside streams and rivers during the salmon spawn in the fall. Every other year females produce one to four young, which weigh only about 2 to 5 kg (1 to 2 lb) at birth. Raised entirely by their mother, the cubs are taught to climb trees at the sign of danger. The Chinook or King Salmon is the largest salmon in North America and can grow up to 58 long and 126 pounds. ...
Habituation to human areas
A fed bear is a dead bear -- bears are transported when possible, but repeat offenders may be killed, when they have associated humans with food sources. With the encroachment of humans into bear habitat, bears may become attracted to human-related food sources such as garbage dumps, litter bins, dumpsters, and so on, and may even venture into human dwellings or barns in search of food. In the U.S., it is not unheard of for a bear to kill and eat farm animals. Once a bear comes to associate human activity with a 'food reward', a bear is likely to continue to become emboldened in its quest for food and human/bear encounters become more likely. There is a saying, "a fed bear is a dead bear", which has come into use to popularize the idea that allowing bears to scavenge human garbage, pet food, or other food sources that draw the bear into contact with humans can result in disaster—for the bear.

Though bears have been relocated to areas distant from human populations, some bears become 'hooked' on a given food source and will return to the same location. Bears that have repeatedly returned to a given area, and thus have become perceived as dangerous, are sometimes killed to prevent human injuries or death. Yellowstone National Park, an enormous reserve located in the Western United States, contains prime habitat for the Grizzly Bear (Ursus arctos horribilis), as well as other Brown Bears, but due to the enormous number of visitors, human-bear encounters are not rare. The scenic beauty of the area has caused an influx of people moving into the area. In addition, because there are so many bear relocations to the same remote areas of Yellowstone, and because male bears tend to dominate the center of the relocation zone, female bears tend to be pushed to the boundaries of the region and beyond. The result is that a large proportion of repeat offender bears—bears that are destroyed for the public safety—are females. This creates a further depressive effect on an already endangered species (the Grizzly Bear is officialy described as threatened in the U.S). Though the problem is most significant with regard to Grizzlies, these issues affect the other types of Brown Bear as well. Yellowstone National Park is a U.S. National Park located in the states of Idaho, Montana, and Wyoming. ...
In Europe, part of the problem lies with shepherds: Over the past two centuries, many sheep and goat herders have gradually abandoned the more traditional practice of using dogs to guard flocks (which have concurrently grown larger.) Typically they allow the herds to graze freely over sizeable tracts of land. As bears reclaim parts of their range, they may take livestock as a means of survival. The shepherd is forced to shoot the bear to protect his livelihood, the community goes up in arms, and often the bears pay the price. In a draw in a mountainous region, a shepherd guides a flock of about 20 sheep amidst scrub and olive trees. ...

Bear encounters It is extremely rare that brown bears kill or seriously injure humans but fatal encounters do happen. There are an average of two fatal attacks a year in North America.1 In Scandinavia there are only three known cases during the last 100 years where humans have been killed by bears. This has usually happened because the bear is injured or a human encounters a mother bear with cubs. Some types of bears such as polar bears, are more likely to attack humans when searching for food while black bears are much less likely to attack. Scandinavia, Fennoscandia, and the Kola Peninsula. ...

The Scandinavian Bear Research project lists the following situations as potentially dangerous: - Meeting an injured bear
- A human suddenly appearing between a mother and her cubs
- Meeting a bear in its cave
- Meeting a bear who has been provoked by a dog
A careful person should always try to avoid these situations. Anybody who walks in a forest where there are bears could carry around a bell since a brown bear's natural instinct is to run away from humans; in groups trail songs are also effective. If camping, do not bring food into the tent and be sure to clean up all garbage-a bear thinks with its stomach. If one still meets a bear it is important to remain calm and to slowly walk in the opposite direction. A running human may trigger the bear's chasing instinct and typically a running bear can outrun a human adult. It is important not to make threatening moves, not to make eye contact nor to shout. If a bear attacks and it is not possible to get away, the person should lie down in a fetal position and put his/her hands around the head to protect from bites. Do not panic. But some say that this method will not work with a black bear, which attacks to kill and to eat. Fetal position is a medical term used to describe the positioning of the body of a prenatal fetus as it develops. ...
