The average life span of a bear depends on the type of bear and whether it was kept in captivity or lived in the wild, but bears can die when they are less than 1 year old or live all the way in their late 30s. Black bears in the wild tend to die much earlier than those in captivity due to an increased risk of death from natural causes, such as flooded dams, hunger, and infection from
The oldest known black bear, who died from natural causes in the wild, was 39 years old, but bears in captivity often live in their 30s. Life expectancy of polar bears living in the wild ranges from 15 to 18 years.
As the snow cover decreases and the days lengthen, a new green begins. At the beginning of summer, bears look for pockets of greenery on wet meadows and along streams and rivers, on avalanche slopes, in aspen forests and along swamp edges. Bears that live near human development often find pastures on the grass of golf courses, ski trails, parks and other urban greenery.

Currently, the polar bear is listed in the Red Book as a dying species. Brown bears are under threat. The most dimensional individuals are found in Kamchatka and Alaska. The body weight of some of them reaches 1000 kg, and the height is 3 m.
Territory habitat, lifestyle and nutrition of bears
In Russia, brown bears live in places where there are dense thickets of grasses, shrubs and deciduous trees - in Siberia, the Far East, Kamchatka.
The diet of brown bears mainly consists of grass stems, oak acorns, berries, wheat, oats, and corn crops. However, the bear does not disdain even smaller species of animals and insects. With one blow of his paw, he can strike a boar, a wolf, a fox on the spot. Being close to the pond, he is able to catch fish. When there is nothing to eat in the forest, the animal may attack an apiary or livestock. In hibernation, the bear lies down when it feeds up subcutaneous fat. But there are also rods. They rarely live to see spring.
Brown bear picks a place for a den under tree roots or in a windbreak. His sleep lasts from 70 to 200 days. During this time, losing weight by about 100 kg.
Polar bears live closer to the pole. They are great swimmers, quietly swim deep in the sea for prey. They feed mainly on pinnipeds - the seal, sea hares, etc. They also hunt walrus pups. Do not disdain carrion thrown out by the sea. They move easily on the ice.
Only pregnant polar bears fall into hibernation, the other individuals, if they sleep in the winter, are much less likely than in the summer. The female is forced to look for a den, so that newborn babies are accustomed to the cold climate after being in a warm environment. Pregnancy in polar bears lasts 230-250 days. The cubs are born in November-January and spend several months in a den, eating only mother's milk.
The life span of bears depends on the conditions in which they exist. In the wild, life span is 10 years. In zoos, zoos can live out to 50.
The polar bear lives in the wild for 25-30 years, during which time the female can produce offspring several times, but not all cubs survive. Mortality is very high, ranging from 10 to 30%. In addition, poachers contribute to the extinction of this species.
The average life span of a brown bear is 30 years. The Himalayan black bear can live in captivity for more than 30 years; in nature, however, the life span is slightly shorter. Baribal or black bear lives about 25 years.
How many bears live?
The quick answer is: bears live up to 50 years.
The brown or ordinary bear, as it is often called, is the most famous member of the bear family. And one of the largest - sometimes giants weighing more than one ton come across! Agree, such dimensions are impressive ...
Bears reach sexual maturity by the age of 3, while continuing to grow up to 10-12 years. Life expectancy in nature rarely exceeds 30 years, while in captivity it increases to 50 years. This is due to the fact that although in nature a bear has practically no enemies, strikes between the same males occur quite often. Sometimes - with a fatal outcome. However, the life span of a brown bear is quite high compared to many other animals.
The polar bear is the closest relative of the brown bear. It is believed that the separation between them occurred about 500 thousand years ago. In the future, the crossing of these two species took place, hybridization occurred. Scientists believe that polar bears are descendants of those very hybrids.
As in the case of the brown bear, the life span of a polar bear is 25-30 years in the wild and no more than 45 years in captivity.
Another famous type of bear is the grizzly. It is a subspecies of a brown bear, mostly found in Canada and Alaska. The appearance of a grizzly bear resembles the Siberian subspecies of a brown bear.
Grizzlies live in nature a little less - up to 25 years, and in captivity can live up to 40 years.
Who is a bear
Bears are large predators of the bear family. Bears are viviparous animals and feed on mother's milk.

- great climbing trees
- swim well
- eat everything
- enemies in nature almost do not have.
Not life, but a fairy tale. :)
How long do bears live?
Among other predatory mammals, life expectancy in the wild for bears is one of the longest - up to 30 years. If a bear is kept in captivity in good conditions, then it can live 50 years. However, a zoo cage or circus arena is not the best place for clumsy ones. In captivity they suffer.
The most common types are:
- Brown bear,
- polar bear,
- black bear (30 years old in captivity, only 15 years old in nature),
- grizzly (lives no more than 25 years in nature, and 45 years in captivity).
The life expectancy of bears is affected by the presence of an adequate forage base, the health of the bear, the absence of tigers, wolves and hunters nearby.
Winter is the period when testing the body for endurance. As a rule, all clubfoot winters successfully.
But in order to be so, from the summer the bear must accumulate a sufficient amount of fat. If this does not happen, the bear will wake up from a dream and in the not the best mood will go to look for food.
Since there is no food in the winter in the forest, the bear goes to the human economy and exterminates the cattle, hits the windows in the house. In order to protect themselves, a person is sometimes forced to shoot a bear.
The bears, awakened during hibernation, are especially aggressive and dangerous. They are called rods. Since stagger through the forest with a fierce look.
In childhood I had a big teddy bear. He roared menacingly when he was turned over. I never became friends with him, for me he was angry and scary. Although sometimes it seems that the bear has a cute face with small ears, but still they are the largest predators. I am pleased to share with you the knowledge of these powerful and powerful animals.
Where do bears live and what do they eat
Bears can be found in such corners of our planet:
- Northwest Africa,
- Arctic territory.
There are different types of these predators, but most of them dwells in the forest. Each bear is assigned a separate territory. There they hunt and equip a wintering place. If there is too much food in one area, then there may be more than one bear.
Although bears and refer to predatorsbut in the diet some species includes plant foods:
- berries and mushrooms,
- plant roots.
Panda prefers bamboo among all plants, but polar bears eat only animal products. In addition, some bears like to eat frogs, insects and wild honey.

In nature, they live to thirty years, and in captivity - to 50if they are being looked after properly. On the life span of a brown bear affected by various factors. For example:
- availability of food supply,
- natural disasters.
In captivity this beast lives longerthan in the wild. He does not need to beware of hunters who can wait at any moment. Man provides animal enough foodtherefore, no need to think where to get it. If the bear gets sick, then a veterinarian can helpthat is simply impossible in the wild.
In the forests where the bear lives, can occur firesthat lead to the death of a huge number of individuals. But this scenario is reduced to almost zero when the beast lives “at home”.
Bears have few enemiesbut between them often happen fightsthat are fatal. They can also lead to serious injuries that greatly shorten life expectancy.
How many years have other bears lived
Polar bear, living in the wildcan live up to 25-30 yearsand the one that is in captivity - up to 45 years.
Grizzly very much like the appearance of his brown brother and canlive to be 25 years oldbut if he is under the care of a person, then the duration of his life may already be 40 years.
