Brown bear: brief description, weight, dimensions. Habits of a brown bear. Polar bears - brown bears - photo of bears Bear is a herbivore or carnivore

We all know these powerful animals from childhood. But few people know what types of bears exist. Pictures in children's books most often introduced us to brown and polar bears. It turns out that on Earth there are several species of these animals. Let's get to know them better.

Bear appearance

If we compare bears with other predators, then they differ in the most uniform appearance, features internal structure, sizes. Currently, these are the largest representatives of terrestrial predatory animals. For example, polar bears can reach a body length of up to three meters with a weight of 750 and even 1000 kg!

Animal fur has a well-developed undercoat, it is rather rough to the touch. The hairline is high. Only he cannot boast of such a fur coat - his cover is low and rare.

The color is varied - from black to white, it can be contrasting. The color does not change with the seasons.

Lifestyle

Different types of bears live in a variety of conditions. They feel great in the steppes and highlands, in forests and in arctic ice. In this regard, bear species differ in their diet and lifestyle. Most representatives of these predators prefer to settle in mountain or lowland forests, much less often in treeless highlands.

Bears are active mainly at night. The only exception is the polar bear - a species of animal that leads a daytime lifestyle.

Bears are omnivores. However, some species have a preference for one or another food. For example, a polar bear almost always eats the meat of mammals, for a panda there is no better delicacy than bamboo shoots. True, they supplement it with a small amount of animal food.

Variety of species

Quite often, animal lovers ask the question: “How many species of bears live on Earth?” For those who are interested in these animals, it seems that there are a myriad of them. Unfortunately, it is not. Today, our planet is inhabited by species of bears, the list of which can be presented as follows:

There are subspecies and varieties of these animals, but we will talk about this in another article.

brown bears

These are large and seemingly clumsy animals. They belong to the bear family. Body length - from 200 to 280 cm.

This is a fairly common look. lives throughout the Eurasian and North American forests. Today, this predator has completely disappeared from the territory of Japan, although in ancient times it was common here. On the territory of Western and Central Europe brown bear can be found quite rarely, in some mountainous areas. There is reason to believe that in these areas it is an endangered species. The brown bear is still widespread in Siberia, Far East and northern regions of our country.

Brown bears are sedentary animals. A forest area occupied by one individual can reach several hundred square kilometers. It cannot be said that bears strictly guard the borders of their territories. Each site has permanent places where the animal feeds, builds temporary shelters and dens.

Despite being sedentary, this predator can roam in search of more abundant food over a distance of more than 300 kilometers in famine years.

hibernation

Everyone knows that brown bears hibernate in winter. Previously, he carefully prepares his lair, which he equips in hard-to-reach places - on islands in the middle of swamps, in a windbreak. The bear lines the bottom of its winter dwelling with dry grass or moss.

To safely survive the winter, the bear must accumulate at least fifty kilograms of fat. To do this, he eats about 700 kilograms of berries and about 500 kilograms of pine nuts, not counting other feeds. When there is a lean year for berries, bears in the northern regions make raids on fields sown with oats, and in the south - on corn crops. Some bears attack apiaries and ruin them.

Many believe that during hibernation, animals fall into suspended animation. This is not entirely true. They sleep pretty well. During hibernation, when the animal lies motionless, its cardiac and pulmonary systems slow down their activity. The body temperature of a bear ranges from 29 to 34 degrees. Every 5-10 breaths there is a long pause, sometimes lasting up to four minutes. In this state, the fat supply is used sparingly. If during this period the bear is raised from the den, it begins to quickly lose weight and is in dire need of food. Such a bear turns into a "tramp", or, as the people call it, a connecting rod. In this state, he is very dangerous.

Depending on climatic conditions, the predator can hibernate for three to six months. In the presence of food in the southern regions, bears generally may not fall into continuous hibernation, but fall asleep only for a short time. Females with one-year-old cubs sleep in the same den.

Food

Different types of bears prefer to eat different foods. Animals of this species most often feed on fruits, berries and other plant foods, but sometimes they can eat ants, insect larvae, rodents, along with winter supplies. Quite rarely, males hunt forest ungulates. Despite the outward clumsiness, the brown bear can be very fast and agile. He stealthily sneaks up on his prey and grabs it in a quick throw. At the same time, its speed reaches 50 km / h.

White bears

IUCN- international union Conservation of Nature for the first time in several years has expanded the list of animals that are on the verge of extinction. It has new species. Polar bears were brought not only to this international list, but also in the Red Book of Russia. To date, their number is only 25 thousand individuals. According to scientists, this population will decrease by almost 70% in the next 50 years.

Rare species of bears (you see the photo in our article), to which recently including white individuals, suffer from industrial pollution of their habitats, global warming and, of course, poaching.

Appearance

Many believe that white, polar, northern, sea or oshkuy are polar bear species. In fact, this is the name of one species predatory mammal from the bear family, the closest relative of the brown bear.

Its length is three meters, weight - about a ton. The largest animals are found off the coast, the smallest - on Svalbard.

Polar bears are distinguished from other species by their long hair and flat head. The color can be completely white or with a yellowish tint. In the summer, the fur turns yellow under the influence of sunlight. The skin of these animals is black.

The soles of the paws are reliably protected by wool so as not to slip on the ice and not to freeze.

Lifestyle and nutrition

According to scientists, the polar bear is the most predatory of the entire family. After all, he practically does not consume plant foods. Different kinds bears (whose photos and names are posted in our article) are almost never the first to attack a person. Unlike their counterparts, the polar bear often preys on people.

The main "menu" of these predators are seals, mainly ringed seals. In addition, he feeds on any animals that he manages to kill. It can be rodents, birds, walruses, whales washed ashore. For the predator itself, killer whales are dangerous, which can sometimes attack in the water.

reproduction

In October, females begin to dig a den in the snow. In mid-November, they settle there. Pregnancy lasts 230-240 days. Cubs are born at the end of the Arctic winter. For the first time, the female brings offspring when she is 4-6 years old. Cubs appear once every two or three years. There are from one to three cubs in a litter. Newborns are completely helpless, weighing about 750 grams. The babies begin to see in a month, after two months their teeth erupt, the babies begin to gradually leave the den. They do not part with a bear until a year and a half. Polar bears are infertile, so their numbers are recovering too slowly.

black bear

It is also called baribal. Its body length is 1.8 m, weight is about 150 kg. The bear has a sharp muzzle, high paws with long and sharp claws, short and smooth black hair. Sometimes the color is black-brown, except for the light yellow muzzle.

The black bear feeds exclusively on plant foods - larvae, insects, and small vertebrates.

Pregnancy of the female lasts up to 210 days, cubs are born in January-February, weighing 400 grams, stay with their mother until April.

Himalayan bear

This animal is inferior in size to the brown one. In addition, these types of bears differ in appearance. The Himalayan bear has a more slender physique, a thin muzzle. Thick and lush hair usually has a black color with a white, sometimes yellowish spot on the chest (it resembles the letter V in shape).

Large adults can reach a length of 170 cm with a weight of 140-150 kg. Habitat - East Asia. In the west, it can be found in Afghanistan, Indochina, on the southern slopes of the Himalayas. On the territory of our country, it is found only in the Ussuri Territory, north of the Amur.

In spring it feeds on last year's acorns and pine nuts. In summer, it enjoys eating juicy grass, berries, and insects. There is evidence that in South Asia it often attacks domestic animals and can be dangerous to humans.

There are usually two cubs in a litter. Their weight does not exceed 400 grams. They develop very slowly, even at the age of a month and a half, they are completely helpless.

Spectacle bear

We continue to study the types of bears, getting acquainted with the indigenous inhabitants of South America. He settles in the mountains - from Colombia to Northern Chile. This is a spectacled bear - not a very animal large sizes. Its body, no more than 1.7 m long, weighs about 140 kg.

The bear is covered with thick, shaggy hair of black or black-brown color, with white spots around the eyes (hence its name). Preferring mountains, the animal also often appears on meadow slopes. Its biology is still poorly understood, but at the same time, scientists consider it the most herbivorous in the entire family. He is a lover of leaves and roots, fruits and branches of young shrubs. Sometimes, for his favorite delicacy, he climbs high palm trees, breaks young branches, and then eats them on the ground.

sloth bear

For our compatriots, the last animals on our list are exotic species bears. You can see their photos and names in numerous domestic and foreign publications about animals.

The sloth bear is an inhabitant of tropical countries. He lives in the forests of Hindustan and Ceylon. In length it can be up to 1.8 m, weight is about 140 kg. This is a rather slender animal, on high legs, with huge claws. The muzzle is somewhat pointed. There is a light V-shaped mark on the chest. The bear is active at night. During the day, he sleeps soundly, while (which is typical only for this species), he snores surprisingly loudly.

Gubach feeds mainly on fruits and insects. With the help of huge claws, he easily breaks rotten, dilapidated tree trunks, and then he uses an amazing device that can resemble a pump. The long muzzle of the animal has very mobile lips, which are extended, forming a kind of tube.

The sloth has no upper pair of incisors, as a result of which there is a gap in the oral cavity. This feature allows the animal to extract termites. First, he blows out all the dust and dirt from the “house” of insects, and then draws the prey through his lips extended into a tube.

Mating sloths occurs in June, after seven months 2-3 babies appear. They spend 3 months in the shelter with their mother. At first, the father of the family takes care of his cubs, which is not typical of other bear species.

Panda

This animal, 1.2 m long and weighing up to 160 kg, lives in the mountain forests of the western provinces of China. Prefers loneliness, except during mating. It's usually spring.

Offspring appears in January. Mostly 2 cubs are born, weighing about two kilograms each. Unlike other bears, it does not hibernate. It feeds on various plants, bamboo roots, sometimes small rodents and fish.

Biruang

This is the name of the Malayan bear. This is the smallest representative of the bear family. The length of his body does not exceed 1.4 m, height is no more than 0.7 m, weight is about 65 kg. Despite its modest size, compared to its brethren, the animal is strong. Biruang has a short muzzle, wide paws with powerful curved claws. The body of the animal is covered with smooth, short, straight black hair. On the chest there is a mark of white or orange color, in the form of a horseshoe. The muzzle is orange or grey. Sometimes the legs are also light.

Biruang is a nocturnal animal, so during the day it sleeps and basks in the sun's rays, in the branches of trees. By the way, he perfectly climbs trees and feels completely comfortable on them.

It feeds on young shoots. The female brings two cubs. The animal does not hibernate.

Jackals. Unlike them, clubfoot are more stocky and powerful. Like other canids, bears are predators, but sometimes they feast on berries, mushrooms and honey.

There are also pseudo-toed, not related to canines and even predatory animals. The name bear is given only because of the outward resemblance to the true representatives of the genus.

real bears

The second name of bears is plantigrade. Having wide legs, clubfoot fully step on them. Other canids, as a rule, touch the ground with only part of their paws, as if walking on their toes. This is how animals speed up. Bears, on the other hand, cannot develop a speed of more than 50 kilometers per hour.

Brown bear

Included in Russian bear species, the largest and most popular in the country. However, the largest clubfoot was caught outside the Federation, on the American island of Kodiak. From there they took the beast for Berlin Zoo. I got a bear weighing 1134 kilograms at a rate of 150-500 kilos.

It is assumed that brown came to America about 40 million years ago through the Bering Isthmus. Animals came from Asia, representatives of the species are also found there.

The largest clubfoot in Russia are found on the Kamchatka Peninsula. There giants live 20-30 years. In captivity, with good maintenance, bears live up to half a century.

Polar bear

According to its habitat, it is called polar. The scientific name of the species in Latin is translated as "sea bear". Predators are associated with snow, the expanses of the ocean. In the water, polar bears hunt, catching fish and seals.

The ocean does not prevent the migration of polar clubfoot. On the water, they overcome hundreds of kilometers, working with wide front feet, like oars. The hind legs act as a rudder. Going out onto the ice floes, the bears do not slip, because they have rough feet.

Among terrestrial predators, the animal is the largest. In length, the predator reaches 3 meters. The standard weight is 700 kilograms. So that view polar bear awesome. In nature, an animal has no enemies other than man.

studying types of bears, only at the polar you will find hollow wool. The hair is empty from the inside. Firstly, it gives an additional layer of air in the fur coat. Gas is a poor conductor of heat, it does not release it from the skin of a predator.

Secondly, the cavities in the white hairs are needed to reflect light. In fact, clubfoot hair is colorless. White hair only looks, allowing the predator to merge with the surrounding snow.

Himalayan bear

Otherwise called the black Asian bear. It is distinguished by large ears, an elegant physique by the standards of clubfoot, and an elongated muzzle.

The habitat of the Himalayan extends from Iran to Japan. The predator prefers mountainous areas. Hence the name of the species. In Russia, its representatives live beyond the Amur, as a rule, in the Ussuri region.

Black bear is named for the dark color of the coat. It is longer on the head and neck, forming a kind of mane. There is a white spot on the chest of the predator. However, there are subspecies of the animal without it.

The maximum weight of a Himalayan bear is 140 kilograms. The length of the animal reaches one and a half meters. But the claws of a predator are thicker and larger than those of brown and polar individuals. The reason is the way of life of the black bear. He spends most of his time in the trees. Claws help climb them.

The Asian clubfoot cannot be called a formidable predator. From animal food, the bear usually consumes only insects. The basis of the diet are herbs, roots, berries, acorns.

baribal

Alternative name - black bear. He lives in the North, especially in the east of the continent. The appearance of the predator is close to the appearance of the brown clubfoot. However, the baribal has more protruding shoulders, lower ears and, as the name implies, black hair. However, on the muzzle it is lighter.

The name of the animal is similar to the name of the family to which it is assigned. There are no other members of the family. By the way, this also applies to the little panda. She is also one of a kind.

The closest relative of the koala is, but not a bear at all, and not even little panda.

About 30 million years ago, 18 species of marsupial "bears" lived on the planet. There were also unseen modern man true clubfoot. Among them, 5-6 species became extinct.

extinct bears

The number of extinct bears is vague, as the existence of one species is in question. There is a glimmer of hope that the Tibetan clubfoot still exists, although for a long time it does not fall into the eyes of people and into the lenses of video cameras. If you meet, let the scientists know. The bear looks like a brown one, but the front part of the body is reddish. The withers of the animal are almost black. AT inguinal region red hair. The rest of the hair behind the predator is dark brown. The bear lived in the east of the Tibetan plateau.

California Grizzly

It is depicted on the flag of California, but has not been found in or out of the state since 1922. Then they killed the last representative type of animal.

Bear had a golden coat color. The beast was a totemic among the Indians. The Redskins believed that they were descended from the grizzly, so they did not hunt the ancestor. The clubfoot was exterminated by white settlers.

mexican grizzly bear

Officially declared extinct in the 60s of the last century. The animal was large, weighing approximately 360 kilograms.

The Mexican grizzly was distinguished by whitish claws on its front paws, small ears and a high forehead.

Etruscan bear

Fossil species, lived in the Pliocene. This geological period ended 2.5 million years ago. The second name of the predator is the short-faced bear. This is the one with 13 pairs of ribs.

Skeletons of Etruscan bears are found only in southern latitudes. Therefore, scientists suggest that the beast was thermophilic. It is also known that the extinct animal was large, weighing about 600 kilograms.

Atlas bear

Inhabited the lands from Morocco to Libya. The last individual was killed by hunters in 1870. Outwardly, the animal was distinguished by reddish hair below the body and dark brown above. There was a white spot on the bear's muzzle.

Unlike most bears, the Atlas preferred desert and arid areas. The name of the species is associated with a chain of mountains where clubfoot lived. Zoologists attributed them to subspecies of the brown bear.

Giant polar bear

Appearance of a polar bear was similar to the modern one. Only here in length the beast reached 4 meters, and weighed 1200 kilograms. Such giants lived on the planet 100 thousand years ago.

So far, scientists have found the only ulna of a giant bear. Found a bone in the Pleistocene deposits of Great Britain.

The survival of modern polar bears is also in question. The number of species is sharply reduced. This is due to climate change. Glaciers are melting. Animals have to do more and more long swims. Many predators get to the shore exhausted. Meanwhile, it is not easy for full-powered bears to get food in the snowy expanses.

Omnivorous is a way of obtaining energy and nutrients by consuming the food of an animal and plant origin. Animals with such a diet are considered "omnivorous". Most people, with the exception of vegans who completely exclude animal products, are also omnivores.

Term meaning

The word "omnivorous" comes from the Latin words omnis"everything" and vora, which means "devour or swallow" - so omnivorous means "devouring everything". It's pretty precise definition because omnivores have a variety of food sources, including algae, plants, fungi, and other animals. Some animals may be omnivores throughout their lives, while others may be omnivores at certain stages (for example, some sea turtles).

Advantages and disadvantages

The advantage of omnivory is the ability to find food in a variety of places and habitat conditions. For example, if it is not possible to eat a certain food, an omnivore can quite easily change its diet. Some omnivores are also scavengers, meaning they feed on dead animals or plants, further increasing their feeding options.

Omnivores have to find their own food, and because they have such a varied diet, their ways of obtaining food are not as specialized as those of carnivores or herbivores. For example, carnivores have sharp teeth for tearing and grasping prey, while herbivores have flatter teeth adapted for chopping up vegetation. Omnivores can have a mixture of both types of teeth (our molars and incisors, for example).

The disadvantages of omnivorousness can be well traced on the example of certain types of marine organisms, which, with highly likely able to invade non-native habitats. This has a cascading effect on native species that may be persecuted or displaced by invasive omnivores. An example is the Asian coastal crab, native to the Pacific Northwest. It was introduced to Europe and the USA, while the food and habitat do not match it, and this animal causes significant damage to the existing ones.

Examples of omnivores

mammals

• Pig: This is probably the best-known omnivore and is currently popular with humans, kept as a pet or raised for meat.
• Bear: These animals are one of the most opportunistic creatures, as they adapt very well to different environments. If there are many fruits in the area where they live, then the bears will feed on them. If instead there is a river with a lot of fish, the bear will catch them all day. The panda, a member of the bear family, is also considered an omnivore, as it can diversify its bamboo diet with rodents or small birds.
  The only exception is the carnivorous polar bear, possibly due to the lack of plant food in its natural Arctic habitat.
• Hedgehog: Many people think that hedgehog eats insects and small things, but these little creatures like to occasionally eat fruits and vegetables.
• Other omnivorous mammals: raccoons, mice, squirrels, sloths, chipmunks, skunks, chimpanzees, and of course humans.

Birds

• Crows: As shown in many films, they are always on the lookout for animal remains, but other than dead carcasses, they also tend to eat vegetables when other food sources are unavailable.
• Chickens: they are the complete opposite of a small child, as they absorb everything in sight. Whatever you give her, the chicken will swallow it without a moment's hesitation.
• Ostriches: Although their main diet includes vegetables and plants, these animals are lovers of all kinds of insects.
• Magpies: These birds also eat almost everything, although they tend to become food for dogs and parrots.

marine organisms

• Many types of crabs (including blue crabs, ghost crabs and Asian coastal crabs);
• horseshoe crabs;
• Lobsters (for example, American lobster, real spiny lobster);
• Some sea turtles - the olive turtle and the Australian green turtle - are omnivores. Green turtles are herbivorous as adults, but the young are omnivores. Loggerhead turtles become carnivores as adults, but they are omnivores when they are young.
• Common littorinas - these small snails feed mainly on algae, but can also eat small animals (for example, barnacle larvae).
• Some types of zooplankton;
• Sharks are generally carnivorous, although whale sharks and giant sharks can be considered omnivores as they are filter feeders and feed on plankton. As they swim through the water column with their huge mouths open, the plankton they consume can include both plant and animal organisms. Mussels and barnacles can also be considered omnivores as they filter small organisms (which may contain both phytoplankton and zooplankton) from the water.

Omnivores and levels of the food chain

In the marine (and terrestrial) world there are producers and consumers. are organisms that produce their own food. These include plants, algae, and some types of bacteria. The producers are at the base.

These are organisms that must consume other organisms in order to survive. All animals, including omnivores, are consumers.

There are trophic levels in the food chain, which are the food levels of animals and plants. The first trophic level includes producers because they produce food that feeds the rest of the food chain. The second trophic level includes herbivores that feed on producers. At the third trophic level are omnivorous and carnivorous organisms.

Bears are the largest of the predators living on our planet, and in size and power they surpass the more famous lion and tiger. However, the bears themselves are also very popular - these animals have been familiar to people since ancient times, among the peoples of all continents they were revered as the personification of strength. People, on the one hand, bowed to the irresistible power of the bear, and on the other hand, considered it a desirable and honorable hunting trophy.

Brown bears (Ursus arctos).

In systematic terms, bears represent a small (only 8 species) and fairly homogeneous family of bears. All species of this family have a powerful body, thick strong limbs, armed with long curved claws. All bears are plantigrade, that is, when walking, they rest on the ground with the entire plane of the foot. Because of this, they are not too graceful and maneuverable in movement, the clumsy gait of a bear has become synonymous with clumsiness.

The paws of bears are wide and flat.

However, the bear is not as simple as it seems at first glance, if necessary, it can make jerks at speeds up to 50 km/h. The teeth of bears also differ from the teeth of other predators - they are relatively small, which is due to the nature of their diet. Among bears, perhaps, only white can be called a typical meat-eater, other species are practically omnivorous, and the spectacled bear is even more vegetarian than a predator. The body of all species of bears is covered with thick, coarse hair.

Black bear (Ursus americanus) during molting.

On the one hand, this fur allows bears to endure severe cold and develop the northernmost habitats, on the other hand, it slows down their spread to the south. Modern views Bears live on every continent except Africa and Australia. The koala living in Australia, although it looks like a small bear cub, has nothing to do with these animals.

Bears lead a solitary life and meet each other only for mating. At the same time, the male behaves aggressively and can kill the cubs if they are still near the mother. Bears are very caring mothers and in every possible way protect babies from danger. Different types of bears, although they retain a common typological similarity, differ from each other in appearance, habits and way of life.

Brown bear (Ursus arctos)

It is the second largest after the polar bear. The largest specimens are found in the Far East and Alaska (the so-called Kodiak bears) and reach a weight of 750 kg. Smaller subspecies can weigh as little as 80-120 kg. Brown bears are generally distinguished by a wide variety of subspecies: among them you can find animals of both small and large sizes, with a color from light straw to almost black.

This brown bear has a very light, almost white color.

This is due to the fact that the brown bear occupies the most extensive (in terms of coverage) natural areas) range, and in different parts of it, animals are forced to adapt to different climatic conditions. In general, the further north, the larger the bears, and vice versa. This happens because in the north it is easier for large animals to keep warm, in the south, on the contrary, smaller specimens get an advantage. The range of the brown bear covers the whole of Eurasia and North America except for the extreme south of these continents. Almost everywhere, bears have become rare animals, because of the dense population and lack of territories, they simply have nowhere to live. They have survived in relatively large numbers in the sparsely populated areas of the United States, Canada, and Siberia. By the way, the American grizzly is not a separate species of bear, but just the local name for the brown bear.

A characteristic feature of this species is winter sleep, in which animals spend up to half of their lives. To do this, bears look for secluded lairs in windbreaks, caves, and in the absence of suitable shelters they dig primitive burrows. Such a den very effectively hides the bear from prying eyes all winter. Bears hibernate in October-November and wake up in March-April. All this time they really spend in a deep sleep, from which only serious danger or hunger can awaken. Hungry bears that do not have fat reserves for a successful wintering, come out of hibernation ahead of time or do not sleep at all. Such bears are called "rods". "Connecting rods" are very aggressive and can even attack a person. Usually, bears prefer solitude and try not to catch the eye of a person once again. Moreover, a bear, taken by surprise, can show shameful cowardice for such a giant. Experienced hunters are well aware that from a sudden sound, a bear can experience ... acute intestinal upset! This is where the expression “bear disease” originates.

feed on brown bears almost everything that gets in their way. They eat berries, mushrooms, nuts and other fruits with pleasure, they will not refuse young greenery, they hunt ungulates, ranging from small roe deer to large elk. But their diet is not limited to ungulates alone; on occasion, they can fish, get shellfish, and do not disdain carrion. They especially like ants, which the bear simply licks from the surface of the anthill by the thousands. The bear will not miss the nest of wild bees or the apiary in the hope of getting honey and larvae.

A young brown bear examines the bark of a tree in search of edible living creatures.

The rivers where salmon spawn are under special control by bears. Every autumn, with the start of spawning, bears gather on their shores and begin mass fishing. To do this, the bear enters the water and patiently waits for the salmon to swim by. Fish jumping out of the water on the rapids are caught by bears literally on the fly. Due to such fishing, bears are fattened before hibernation. For the sake of this, they even forget about enmity and tolerate each other, as long as there is enough food for everyone. In search of vegetable food, bears show miracles of dexterity and easily climb even trees, which is surprising for animals of such dimensions.

Roaring males enter into fierce fights with each other.

The bear rut lasts all summer.

She-bear feeds her cubs lying down.

At the same time, bears can cripple and even kill the enemy. Pregnancy is relatively short - 6-8 months. The bear gives birth in a dream, more precisely during hibernation 2-3 (rarely 1 or 4) cubs. Babies are born very small, weighing only 500 g. They spend the first months of their lives in a den with their mother, from where they come out already grown up.

Little cubs are very meek and obedient. This property is often used by animal trainers who bring up bears with early age. Bear cubs quickly learn tricks and perform them until about 2-3 years old. Then matured animals become dangerous and, as a rule, give way to younger ones. In nature, cubs also stay near their mother for two years. Moreover, the older cubs of the last year help the bear look after the younger ones. At the age of two years, young bears leave their mother and begin an independent life.

Polar bear (Ursus maritimus).

The largest species of bears and land predators in general. The length of large males can reach 3 m, weight - 1000 kg! The polar bear has the shortest ears among other species, this protects the animal from heat loss. Although the polar bear looks white, its fur is actually transparent because the hairs are hollow inside. But the skin of a polar bear is jet black.

The fact that the polar bear has black skin can only be guessed by looking at its feet.

This coloration is not accidental. sunlight passes through colorless hairs and is absorbed by dark skin, thus, solar energy is accumulated in the form of heat on the surface of the body. Polar bear fur works like a real solar battery! The hollow hairs often become a haven for microscopic algae, which give the coat a yellowish, pinkish, and even green tint. This structure of the fur is very rational, because the polar bear lives to the north of all other species. Its habitat is circumpolar, that is, it covers the north pole in a circle.

This polar bear living in the zoo is clearly getting bored with the heat.

Polar bears can be found throughout the Arctic: on the mainland coast, remote islands and in the depths of eternal polar ice. Polar bears, like no other, are prone to vagrancy, they do not have permanent protected areas. Due to the harsh living conditions, they are forced to constantly wander in search of prey. Polar bears are very well adapted to such journeys, they are very hardy, endure long-term hunger well and are excellent swimmers, which helps them to overcome large expanses of free water between continents and islands. A record is known when a polar bear spent 9 (!) days in the water. Due to global warming, the surface of the ice in the Arctic is shrinking all the time, and animals are making such forced swims more and more often.

In a foggy haze, polar bears cross the sea.

Polar bears are exclusively carnivores. They can only occasionally eat shoots of polar plants and berries in the tundra, but otherwise fish and seals form the basis of their diet. Bears lie in wait for seals near the holes in the ice, through which they come to the surface. A bear can spend several hours patiently waiting, and when prey appears, it crawls up to it, covering its dark nose with its paw. Polar bears have an exceptional sense of smell and vision, which allows them to detect prey many kilometers away. In times of famine, they do not disdain carrion, eating the carcasses of dead whales.

Two polar bears share a whale carcass. Seagulls are spinning nearby - the eternal companions of bears. They accompany predators in the hope of feasting on the remains of their prey.

In polar bears, males never hibernate, and females equip dens only in connection with the onset of pregnancy. The polar bear's den is a simple snowdrift formed by snowdrifts around the animal's body. Due to the lack of places suitable for arranging dens, females often gather on a limited territory of convenient islands, creating a kind of "maternity hospital". Bear cubs, like all bears, are born tiny and helpless, they leave the den only at 3 months of age.

A female polar bear with a cub is resting right on the snow.

Unlike brown bears, polar bears are curious and fearlessly approach human habitation. Although they are formidable predators, they rarely show aggression towards humans. But people often fall into unreasonable panic and shoot animals simply out of fear.

Black bear, or baribal (Ursus americanus).

The range of the black bear covers almost the entire North American continent, where it often coexists with the brown bear. This species is not particularly rare, and thanks to protection in reserves, in some areas it even enters the outskirts of cities. In general, this animal resembles a medium-sized brown bear weighing 120-150 kg. But there are some differences: the black bear's fur is usually darker, the muzzle is more elongated and colored white or yellowish, the baribal's ears are relatively large, and the claws are long.

In the brood of a black bear, you can often find cubs of different colors.

These claws help the black bear climb trees, because it is an excellent climber. Baribal loves to climb and feed on trees more than other bears.

While the mother is busy looking for food, the cub learns to climb trees.

The black bear feeds on the same food as the brown one, but plant foods predominate in its diet; it never attacks large animals. Yes, and his character is more docile. Smaller, and therefore less dangerous, this bear often approaches human habitation in search of some kind of garbage.

Himalayan bear (Ursus thibetanus).

These bears are somewhat smaller than brown bears, reaching a weight of 140-150 kg.

Himalayan bears are only black in color, and on their chest they have a white or yellow spot in the form of the letter V.

The Himalayan bear has the largest ears relative to body size. The Himalayan bear lives only in the Far East, from Primorye in the north to Indochina in the south. By way of life and habits, this bear is also similar to the brown one, only its character is calmer and plant foods predominate in the diet. Distinctive feature This species is that the bears do not arrange traditional dens, but prefer to settle down for the winter in hollows.

Sloth bear (Melursus ursinus).

The territorial neighbor of the Himalayan bear - the sloth bear also covers Southeast Asia. But appearance animal is very original. Gubach is a kind of "hippie" in the bear family. What self-respecting hippie doesn't try to stand out among his surroundings?

The coloring of the sloth bear looks a lot like the Himalayan bear, but its coat is very long and thick. The claws are also of extraordinary length.

And the sponger surprises. First of all, a way to get food. The sloth eats various plants, invertebrates and other small animals. But he has a special passion for ants and termites. For the destruction of durable termite mounds, the long claws of the sloth are used. When sloth gets to the contents of the mound, he first blows air through his lips, folded with a tube, and then begins to suck insects through the gap between the front teeth. For this reason, he even lacks front incisors. During feeding, the sloth bear resembles a vacuum cleaner and makes no less noise. In other moments of his life, the sloth bear also shows carelessness: he usually sleeps during the day and, unlike other bears, does not seek to hide in the wilderness: you can catch a sleeping sloth right in the middle of some clearing, but this meeting is unlikely to be a surprise. The fact is that the sloth also snores loudly and can be heard from afar. The sloth has reasons for such behavior - it simply does not have natural enemies. The only danger may be the tiger, with which the sloth is on an equal footing. By the way, the sloth is the main contender along with the Himalayan bear for the role of Baloo from Rudyard Kipling's book. Most likely, the author had it in mind when he wrote The Jungle Book.

Malayan bear (Helarctos malyanus).

The smallest species of bears, its mass reaches only 65 kg.

His coat is very short, which makes the Malay bear look different from a "real" bear.

It lives in Indochina and on the islands of the Malay Archipelago. This beast refutes the myth that a bear can only be found in the northern taiga.

Perhaps the Malayan bear is the only one that can be seen on a palm tree.

It is omnivorous, but due to its small size it preys only on small animals. This bear does not hibernate.

Spectacled bear (Tremarctos ornatus).

The only member of the bear family living in South America. It inhabits mountains and foothill forests. This is a medium sized animal.

The spectacled bear got its name because of the round spots around the eyes, resembling glasses.

The spectacled bear is the most herbivorous of all. This is a very rare animal that few people managed to see in natural conditions. The world's leading zoos are participating in the spectacled bear breeding program.

And where is the panda - the most interesting view bears? But whether a panda is a bear is a question that has haunted scientists so far. Many zoologists tend to believe that the panda is not a bear at all, but a giant representative of the raccoon family. For this reason, the story about pandas is on a separate page.

bears are herbivores or carnivores

1. omnivores!!
2. Browns are omnivores. Whites are predators
3. Bears are omnivores. They eat grass, berries, mushrooms, they will not refuse fish, especially meat, fatten up - they eat everything until they are completely stupefied.
   But pandas only eat bamboo, while polar bears prefer seal and seal fat.
4. predators of course
5. The bear is an omnivore, just like humans.
6. predators, but from hunger they can pick up raspberries and chew grass =)
7. 100% carnivorous predators, because they eat meat and hunt. Only carnivores can hunt and eat meat, first of all, and only then fish, mushrooms, nuts, honey, berries, grass, roots. But herbivores cannot eat meat.
8. omnivorous
9. omnivores
10. omnivorous
11. the bear is omnivorous. He eats almost everything that can be eaten. in the summer, plant foods predominate, most of the animal protein in the bear's diet is small animals. rodents. insects. the bear is engaged in hunting directly, especially hunting for large animals, extremely rarely only in the absence of more accessible and less “dangerous” food
12. Predators))
13. Differently
14. white bear, grizzly bear, spectacled bear and many other members of the bear family eat wild berries, nuts, honey, rodents, carrion, large mammals, and other plants. FROM THE ORDER THEY ARE PREDATORS. and here is a koala belonging to the family marsupial bears- herbivore bear.
15. Bears are omnivores. In principle, they eat plant food all the time, and animal food only when it falls into their paws.
16. Medve#769;zhy (lat. Ursidae) is a family of mammals of the order of carnivores. They differ from other representatives of the canine in a more stocky physique. Bears are omnivorous, climb and swim well, run fast, can stand and walk short distances on hind legs. They have a short tail, long and thick hair, as well as excellent sense of smell and hearing. They hunt in the evening or at dawn. Usually fearful of humans, but can be dangerous in areas where they are used to humans, especially polar bears and grizzly bears. Immune to bee stings. In nature, they have almost no natural enemies.
17. Anatomically predatory. Teeth, then - with. And constantly on plant foods, he can not. But in last years in many regions, the bear is increasingly using plant foods. In this regard, its numbers are growing, in some places it is much larger than the wolf. That is, it sort of climbs off the top of the food pyramid.
