Once there were many brown bears in nature.Among them were families and groups. Now they left only the division on the basis of geographical location. Many people have an idea why a bear falls into a hibernation. But it makes sense to understand whether all "club-footed" are inclined to this? Perhaps in the southern regions there are animals that are awake all year round?
Distinctive features
The brown bear is a large animal.Individuals living in the European part of the continent, reach 1.4 - 2 m with a weight of up to 400 kg. Bears of Kamchatka and Alaska can weigh up to 1000 kg. Such a giant, rising to its hind legs, has an increase of up to 3 m.
The brown bear's body is powerful.The head is massive, with small eyes and ears, a high withers, thick fur, wide post and a short tail - a typical image of a brown bear. Claws (up to 10 cm long) on powerful five-fingered paws do not hide.
Bears are animals that stiff.If necessary, for a short time develop a speed of up to 40-50 km / h. Water obstacles overcome with ease. Take shelter in a tree from an angry bear will not work.
In their nutrition, vegetable food predominates (by ¾).Primarily these are berries, acorns, nuts, roots and tubers of plants, as well as their juicy stems. It is this feature that is decisive in understanding why a bear falls into a hibernation in a harsh period. As for color, the main color is brown. The shade of the coat can be significantly different even in individuals living in the same area (from black, pale-gray and gray to reddish-brown).
Lifestyle
Bears define their territory and fixborder labels. It is believed that they live a settled life, although they can make migrations related to finding more suitable feeding places. In early spring they are looking for glades where snow falls and the ground thaws faster. During the activity of the nest they can leave the forest thicket to open places. During spawning they make hikes to the rivers for hunting fish in shallow water.
But to move to the southern regions for the winterthey can not - this is another compelling reason in understanding why bears fall into hibernation in the winter. They lead a sedentary lifestyle and are forced to return to traditional habitats. With the advent of autumn, it is becoming more difficult to find food - to have to look for a way to wait out the cold.
Why bears fall asleep in winter
The ability to fall asleep in the cold is inherent andother animals. By the way, not only the winter period causes hibernation. In a desert area, small rodents can enter into a drowsy state and in summer, during a drought period. Under adverse conditions, unplanned dormancy may last until the very spring.
Brown bear is such a long rest to affordcan not. The period of hibernation can vary from 2.5 to 6 months. But sometimes it lasts and more, if circumstances so require. When asked why the brown bear falls into hibernation, rather than harvests of roots, nuts and acorns for the winter, it is difficult to answer. Apparently, he prefers to store them in the form of subcutaneous fat - so reliable, and even warmer.
It should be made clear why the bear falls intoHibernation. This is due to extreme necessity. Only in this way animals can survive in winter. At the same time, it should be noted that individuals living in southern regions with a sufficient food base can do without seasonal sleep all year round.
It is also worth dispelling the myth of alleged abilitybears suck paws and thus eat in winter. This habit, as experts say, is related to the peculiarity of the molting of the soles of bears. Rough skin from them during the stay in the lair peels off. This is due to lack of movement and load. Young and tender skin on the soles of cold. Therefore, bears warm her with their breath and lick their tongue.
Cranks: why the bear hibernates in winter
What happens if you wake the beast in the den?Hibernation of the bears is superficial. An anxious animal will wake up and is able to react quickly to danger or sudden changes in conditions. As a rule, the awakened bear will look for a new den, if the old leg is unsuitable for sleeping.
In this case, why does the brown bear run intoHibernation in winter again, rather than waiting for spring? This is the easiest way to survive. But there are situations where, for various reasons, animals do not eat enough fat for the summer. Lying in a lair in this condition until the spring they can not. Hunger forces you to leave the den and go in search of food. Korenev, nuts, acorns and other food for him under the snow can not be found. The only way to survive is to engage in predation.
Under such circumstances, the bear decidesattack the weakened animals and even predators. He is ready to take the prey from wolves and foxes, there is carrion. He can enter the surrounding settlements, destroy apiaries, attack livestock and people. Meeting a man with a starving bear-rod can end sadly - this must be remembered and understood.
