Characteristic

Bearish- family mammals squad predatory. Different from other representatives canids stockier build. The Bears omnivorous, climb and swim well, run quickly, can stand and walk short distances on their hind legs. They have a short tail, long and thick wool, and also excellent sense of smell. They hunt in the evening or at dawn. They are usually afraid of humans, but can be dangerous in places where they are accustomed to people, especially polar bear and the bear grizzly. Immune to bee bites. In nature natural enemies almost none.

Bears breed from 3-4 years of age, but not annually, but at intervals of 1 to 4 years. The number of cubs in a litter is from 1 to 5. Newborn cubs are blind and helpless, weighing only from 90 to 680 grams. In hibernating species, birth occurs in winter, in den. Bears are monogamous, but pairs are short-lived and the male takes part in caring for the offspring. Milk feeding lasts from 3.5 to 9 months, but the young remain with their mother for at least 18 months. The older cubs staying with their mother help the mother take care of the younger brothers and sisters. Life expectancy is long, 25-40 years. A brown bear can live longer than 45 years in captivity.

It is easily recognized by its long and mobile snout, and its lips are bare and can protrude strongly, forming something like a proboscis.

The dimensions are small. The body length of the sloth fish is up to 180 cm, weight is 54-140 kg. The body is massive, with high legs. The head is large, with a flat forehead and a strongly elongated muzzle. The fur is long, shaggy, forming a kind of unkempt mane on the neck and shoulders. The color is primarily glossy black, but often mixed with grey, brown or reddish hair. Sometimes red or reddish-brown individuals are found. The end of the muzzle is always dirty gray; there is a distinct light spot on the chest, similar to the letter V or Y. Large sickle-shaped claws are adapted for climbing trees, digging and destroying termite mounds. The lips and muzzle are almost bare and very mobile, and the nostrils can close at will. The teeth are small, and the two central upper incisors are missing, creating a passage that continues the “tube” of elongated movable lips; the tongue is very long. Leads nocturnal, sleeps during the day The sense of smell is well developed, but vision and hearing are weak.

weigh 120-140 kg. Females are noticeably smaller.

Himalayan

The fur is short, shiny, silky; usually black, but there are individuals of brownish or reddish color. There is always a white, sometimes with a yellowish tint, V-shaped spot on the chest; it resembles a crescent moon. leads a semi-arboreal lifestyle - it obtains food in trees, where it also escapes from enemies and vile .

The food of the Himalayan bear is 85% of plant origin: pine and other nuts, acorns, various berries and fruits, shoots of herbs and shrubs, succulent bulbs and rhizomes. It rarely preys, but does not disdain carrion. From protein foods, it feeds on ants and other insects, mollusks, and frogs. Doesn't attack people.

In winter it goes into hibernation. Arranges dens in soft hollows tree species - poplars or linden trees. Life expectancy is about 25 years.

panda (bamboo bear)

The panda reaches 1.2-1.8 m in length and weighs 17-160 kg. has quite a long tail(10-15 cm). The body is massive, covered with thick white fur with black spots around the eyes, black ears and black paws. Short thick hind legs have sharp claws. On the soles and at the base of each toe, bare pads are well developed, making it easier to hold the smooth bamboo stems.

Giant pandas have unusual front paws, With " thumb"and five ordinary fingers; They only eat one bamboo, but on occasion they eat eggs, small birds, animals and some insects. Animal food is an essential source for pandas squirrel An adult panda eats up to 30 kg of bamboo and shoots per day. Reproduction of pandas in captivity is extremely rare.

This animal is of medium size: its body length is 150-180 cm, weighs from 70 to 140 kg. The fur is shaggy, coal-black or black-brown. There are white or yellowish rings around the eyes, connecting with a white semicircle on the throat. Some individuals have no spots. The muzzle is shorter than that of other bears.

Lives until 21 years old. These are nocturnal and crepuscular animals that do not hibernate (although they can make dens for themselves).

It feeds on grass shoots, fruits and rhizomes; sometimes climbs tall palm trees, breaks branches, and then eats them on the ground. They tear up anthills and termite mounds; relatively narrow muzzle and long tongue allow spectacled bears to penetrate deep into the destroyed dwellings of insects and feed on them.. They do not disdain carrion.

Spectacled bears are usually solitary, but not territorial animals .

Polar bear

Polar bear from others bears distinguished by long neck and flat head . Leather his is black. The color of the fur coat varies from white to yellowish; In summer, the fur may turn yellow due to constant exposure to sunlight. The soles of the feet are lined with wool to prevent slipping on ice and freezing. There is a swimming membrane between the toes, and the front part of the paws is lined with stiff bristles. Large claws can hold even strong prey. Its length reaches 3 m, weight up to 1 ton. Usually males weigh 400-450 kg, body length 200-250 cm, height at the withers up to 130-150 cm. Females are noticeably smaller (200-300 kg). Solitary animals. Even on land, polar bears are fast and agile, and in water they swim and dive easily. Very thick, dense fur protects the bear's body from cold and getting wet in icy water. An important adaptive role is played by a thick layer of subcutaneous fat up to 10 cm thick. White coloring helps camouflage the predator. Well developed sense of smell, hearing and vision

General size, color and lifestyle are appropriate environment, sometimes manifest themselves individually. It cannot be said that according to the listed characteristics, grizzlies are fundamentally different from Siberian brown bears. Average weight exceeds 450 kg.

The basis of coastal feeding populations consists of salmonids fish, while their forest counterparts are more vegetarians And scavengers(hunt for ungulates takes up a relatively small percentage of the diet). In the southern part of the range, animals avoid humans, in the northern part they allow them to come at a fairly close distance.

Baribal is different from brown bear smooth black fur and more small sizes. An adult male reaches a length of 1.4-2 m and weighs 363 kg. Females are smaller - 1.2-1.6 m and 39-236 kg. Height at the withers is up to a meter. The tail is shorter - 80-120 mm. Other differences include a sharp snout and tall limbs with short feet.

The baribal's fur is shiny, pure black, with a light spot on the muzzle and sometimes on the chest, but other color options are known. Black bears are typically territorial and solitary animals; The baribal feeds on plant foods (acorns, hazelnuts, cranberries , blueberries , raspberries , blackberries , strawberries , dandelion , clover)insects( ants , termites , wasps , bees) and their larvae, sometimes meat, fish ( salmon), occasionally attacks livestock - sheep And pigs .

Baribal (black bear)

The smallest representative of the bear family, weighing 27-65 kg. It is a stocky, strong animal with a short and wide muzzle. The ears are short and rounded. The limbs are high with disproportionately large paws; the claws are very large, curved. Feet are bare. The fangs are small; The molars are small and flattened.

The biruang's fur is short, stiff and smooth. The color is black, on the face it turns into roan-yellow. Sometimes the limbs are also light brown. On the chest there is usually a large whitish or red spot in the shape of a horseshoe, reminiscent in shape and color of the rising sun. It is well adapted to climbing trees and, being nocturnal animals, often sleeps all day long or sunbathes in tree branches. Does not hibernate. Omnivorous.

Presentation “Wild Animals” “Brown Bear” Educator: Dyachenko Valentina Viktorovna. I Qualification category

Who will be the first to guess my riddle? He lives in the thicket of the forest, and is reputed to have a sweet tooth. In the summer he eats raspberries and honey, and sucks his paw all winter. He can roar loudly, and his name is... (Bear)

Well done, you guessed it, and today I will tell you about the bear. The bear is a large predatory animal. He lives in the forest.

He has a large head, small round ears, small eyes and a tail.

The paws have long claws. Like these ones! And the paws have long, sharp claws, thanks to which the bear climbs trees well.

The bear's fur is thick and warm, so it doesn't freeze in winter. Do you know what color a bear's fur is? Yes, brown, but more often they say brown, and the bear is called a brown bear.

They say about the bear - clubfooted, clumsy, but do you know why? It’s just that when the bear walks, it steps on both left paws or both right paws at once. So it seems to us that he is waddling from side to side. Meeting a bear in the forest is very dangerous. The bear runs quickly and easily catches up with a person. Since the bear's hind legs are longer than its front legs, the bear runs uphill faster than downhill.

Like all wild animals, bears get their own food. The bear loves mushrooms, berries, nuts, acorns, roots, and fruits. Enjoys eating mice, frogs, worms, and insects.

The bear is also an excellent fisherman. Loves to catch fish.

At the end of winter, 2-3 or even 5 cubs appear in the den.

Little cubs have white spots on their necks. Like these ones. They look like collars, but they are beautiful! As they grow older, the spots will disappear.

The mother bear teaches the grown cubs how to hunt.

Since the summer, the bear has been looking for a secluded place for its den. Late autumn he digs a den under the roots of an old tree. He works for two or three days. Then he drags leaves, grass, moss into the den, covers it with spruce branches and lays down in the den, roars a little more, as if warning everyone - do not disturb sleep, and falls asleep. They say that the bear has gone into hibernation.

The bear will wake up only in the spring, when the snow melts.

Goodbye Mishka!

Brown bear (Ursus arctos), a predatory mammal of the bear family (Ursidae). Distributed in North Africa (Atlas Mountains), Europe, Asia up to North America, where it is known as “grizzly”. The brown bear is a forest animal, living mainly in continuous forests. In Russia - throughout the forest zone of Eurasia, in the Caucasus mountains and Central Asia. In most of the region's distribution, the brown bear is relatively few in number. Exterminated in places. The brown bear forms several subspecies (geographical races), differing in size and color. The largest brown bears live in Kamchatka and Primorsky Krai (weigh 300 kg or more).

The brown bear's food is predominantly plant-based: berries, acorns, nuts, rhizomes, as well as insects, worms, lizards, frogs, rodents and other small animals. Sometimes it attacks young ungulates; on Far East The food item is fish (anadromous salmonids).

Since autumn Brown bear lies in a den. During winter sleep, it exists due to fat reserves accumulated in the summer. The brown bear's winter sleep is shallow; in case of danger, the animal wakes up and leaves its den.

Slide 6

With the onset of warm weather, brown bears, who have become very thin over the winter, begin to feed intensively. In the south, where winters have little snow, the brown bear does not lie down in a den. Estrus in females lasts from May to July. The duration of pregnancy is about 7 months. Once every 2 years, from the end of December to the beginning of February, the female usually gives birth to 2 cubs, which she feeds with milk for about 4 months. A brown bear reaches sexual maturity at 3 years of age. The commercial value is small. The skin is used mainly for carpets, the meat is used for food. In some places, brown bears damage grain crops and occasionally attack domestic animals and humans. The number is declining in places where forests are developed by humans, as well as as a result of hunting.

Slide 2

What is the life expectancy and weight of a Brown Bear?

In nature they live for 20-30 years, in captivity they live for more than 50 years. The weight of an adult brown bear ranges from 80-600 kg and, despite intensive hunting, bears weighing up to 750 kg are still found. The largest bears are found in Alaska and Kamchatka - they weigh 300 kg or more, and there were giants weighing 600-700 kg. The largest bear captured very successfully, named Kodiak for the Berlin Zoo, weighed 1134 kg. Average weight: males: 135-390 kg, females: 95-205 kg. In autumn, a bear's weight can increase by about 20%.

Slide 3

What is the behavior of the Brown Bear?

The brown bear is active more often at dusk, in the mornings and evenings, but on rainy days it wanders throughout the day. Daytime vigil is typical for bears in the mountains of Siberia. The seasonal cyclicality of life is clearly expressed. Bears are very sensitive; they navigate the terrain mainly with the help of hearing and smell; their eyesight is weak. Brown bears can smell rotting meat more than 2.5 km away. Although the bear's body weight is large and it seems clumsy, in fact it is a silent, fast and easy-to-move animal. The bear runs extremely fast - with the agility of a good racer - at a speed of over 55 km/h. He is a good swimmer, can swim 6 km or even more, and willingly swims, especially in hot weather. In his youth, a brown bear climbs trees well, but in old age he does this reluctantly, although it cannot be said that he completely loses this ability. However, it moves in deep snow with difficulty. When encountering a dangerous opponent, the bear emits a loud roar, stands on its hind legs and tries to knock down the enemy with blows of its front paws or grab him. In the winter, looking for a den, bears can go far from their summer area.

Slide 4

What is the height and length of a polar bear?

The polar bear, obviously, can be considered the largest living land predator: the body length (without tail) of adult males is usually 200-250 cm, rare bears reach 285 and, as an exception, 302 cm. Height. At the shoulders 130-140, occasionally 150 cm. The body length of adult females usually varies from 160 to 250 cm. The length of the tail (with terminal hair) is 20-22 cm.

Slide 5

What is the mass of a polar bear?

The weight of polar bears varies greatly depending on the degree of their fatness. In exceptional cases, a male can reach 800-1000 kg. The usual weight of adult males in Greenland is about 450 kg, only well-fed individuals weigh up to 500 kg, and well-fed females - 350-380 kg. In Canada, the weight of male polar bears 1 caught for tagging did not exceed 425 kg, and that of females did not exceed 216 kg. The males studied on Spitsbergen in August - September 1967 weighed 350-400 and only one 510 kg, females - 200-250 and 320 kg, respectively. In the autumn of 1968, males over the age of 5 years were studied there, they weighed 220-530 kg , including the mass of two of them, reaching 15 years or more, was 450 and 530 kg; the weight of females over 4 years of age varied from 180 to 350 kg, two females over 10 years old weighed 290 and 320 kg.

One morning at the zoo there was a serious, even heated argument. Suddenly the neighbors started - Brown and White - two bears. - How, buddy, did you become white? What, are you dirty with chalk? - What are you brown? Are you all dirty with soil? You see, the bears are not amused, they are worried about the color of their fur. Who painted these bears in different colors, please answer?
