Walking on all fours, brown bears have a height of about 3. They can reach heights of feet 1. There are regional size differences among bears; brown bears are generally larger in the north—likely due to the colder climates. The largest of the brown bears, is the Kodiak bear Ursus arctos middendorffi , is found only in the Kodiak archipelago islands along the southeastern coast of Alaska.

Kodiaks can stand more than 10 feet 3 meters tall on their hind legs and 5 feet 1. Brown bears exhibit sexual dimorphism, with males being significantly larger than females. This size difference is a result of larger males having better mating success than smaller males. Male bears are close to 2 times heavier than females. A typical adult male weighs between pounds kilograms , while the adult female weighs between pounds kilograms. Kodiak bears, the largest of the species, can weigh over 1, pounds kilograms , as can those brown bears on the Alaska Peninsula as featured in episode 1 of Bears of the Last Frontier.

The coloring of brown bears differs according to environmental conditions, such as diet and temperature, which are specific to the geographical area in which they live.

Their fur can be whitish, blond, red, or black, in addition to the typical dark brown. Though brown bears are often perceived as carnivores, they are actually omnivorous.

Depending on season, habitat, and region, they can eat grasses, berries, sedges, fungi, mosses, roots, nuts, fruits, honey, insects, birds, and fish trout, bass, and particularly adult salmon returning to rivers to spawn. Bears will also hunt mammals such as rodents, mountain sheep, caribou, elk, moose, and will eat carrion, as well.

To prepare for hibernation, in the summer months bears can consume up to 90 pounds 40 kilograms of food a day, and gain up to 3 pounds 1. Brown bears live in a variety of habitats, including forests, woodlands, alpine and subalpine meadows, and even the Arctic tundra.

Following the food, they relocate depending on the seasons—living at lower elevations in the spring and higher elevations in wintertime. Brown bears are the most widely distributed bears in the world. The Alaskan population is estimated at a healthy 32, individuals. These five ecosystems combine for a total of roughly 1, wild grizzlies still persisting in the contiguous United States.

Unfortunately, these populations are isolated from each other, inhibiting any genetic flow between ecosystems. This poses one of the greatest threats to the future survival of the grizzly bear in the contiguous United States.

Due to the lack of human development in its remote Arctic habitat, the polar bear Ursus maritimus retains more of its original habitat than any other remaining large carnivore. Approximately 25, polar bears live in the northern regions of Canada, Alaska, Russia, Norway and Greenland.

The global polar bear population, estimated to be 22,, bears, is relatively stable. The same records show that black bears have killed 78 people and polar bears have killed 11 people during the same period. The NPS opens in new tab recommends that people keep their distance from bears, make an effort to be noticeable when in a bear’s environment and avoid surprising them.

Bear behavior can be unpredictable, and there isn’t a strategy to deal with bear attacks that will work in every situation. According to the NPS, if attacked by a grizzly or brown bear, you should leave your backpack on if you have one and play dead by lying flat on your stomach with your hands clasped on the back of your neck and legs spread — this makes it harder for the bear to turn you over.

Grizzlies usually attack with greater intensity if you fight back, so it’s best to stay still until the bear leaves you alone. However, you should fight back vigorously if the attack persists by striking the bear in the face with anything available to you, according to the NPS. The NPS advice differs for black bear attacks: During a black bear attack, it is never advisable to play dead. Victims of black bear attacks should try to escape or fight back if no escape is possible.

People who are in a tent when attacked by any bear, or stalked and then attacked, should not play dead and should instead immediately fight back. In this scenario, the bear sees humans as prey, the NPS says. Related: Woman killed in unusual grizzly bear attack opens in new tab.

The vast majority of North American brown bears, which includes most grizzly bears, live in Alaska. Grizzly bears also live in Canada and the U. Grizzly bears are adaptable and occupy different habitats across their range, including coastal areas, mixed-conifer forests, grasslands, mountainous forests and Arctic tundra, according to the Center for Biological Diversity.

Grizzlies are solitary but do sometimes interact with other bears. When grizzly bears rub trees with their backs, they’re not trying to scratch an unbearable itch.
