Gliding squirrel. The American flying squirrel is not an ordinary squirrel. Squirrel in winter. How a squirrel prepares for winter

home In this section you will learn about some interesting features

protein. Squirrels live mainly in the forests of Europe. They reach 25 centimeters in length; Thus, each of you can fit two such squirrels in your hands. These animals have a thick fluffy tail

, reaching the length of the squirrel itself.

Thanks to this tail, squirrels manage to jump from tree to tree without losing their balance. TEETH THAT GROW AGAIN EVEN IF THEY BREAK Squirrels have very strong and healthy teeth - not at all like ours. In the front of the squirrel's mouth there are incisors, which break and gnaw hard materials; in the back of the mouth there are molars. If we want to eat a nut, then in order to break it, we use a fairly strong stone or a specially made one.

. These same miniature animals can easily perform such work with their incisors.

Have you ever wondered how strong a squirrel's teeth remain throughout its life, or how a squirrel with broken teeth will chew nuts? Nature has given squirrel teeth one very important property. You will probably be surprised to learn that if a squirrel’s teeth break or wear out, new ones immediately appear in their place. Worn teeth constantly grow back from the root., which allow you to accurately determine distance, strong claws and a tail designed to maintain balance. Have you ever thought about who gave squirrels these special abilities and taught them to use them? How do squirrels know how to behave, what skills and when to show them? After all, squirrels, even if they wanted to, cannot take a ruler in their paws and measure the height of each tree or the length of the branches, but then how do they determine the distance to jump? Besides, how can squirrels jump so fast and at the same time remain safe and sound, and yet there are so many obstacles and dangers on their way: if the squirrel were not so dexterous, it would have collided with something long ago and would have been injured, or maybe (it’s scary to even think about it!), and would you even fall?

In addition to the talent of an agile athlete, squirrels have all the necessary abilities and physical data to be able to get seeds hidden under the strong shells of nuts, because squirrels are great lovers of chestnuts, hazelnuts and seeds found in spruce cones that grow on the tops of tall trees .

Squirrels are adapted to make it easy for them to find food.

In winter, when everything edible is hidden under the snow, it is difficult for squirrels to find food. Therefore, these prudent animals prepare provisions for the winter in the summer. It is interesting that when creating food supplies for the winter, they show amazing accuracy. As if realizing that fruits and meat quickly spoil, they do not stock up on this food. Squirrels prepare only long-storable foods for themselves for the winter, such as nuts and pine cones.

Squirrels storing food for the winter find nuts hidden in different places thanks to their excellent sense of smell. They can smell nuts even if they are hidden under a 30-centimeter layer of snow.

Squirrels bring food for the winter to their burrows, where they hide it in several places. Later, they forget the location of most of these places. Over time, new trees grow from the supplies not used by the squirrels.

Did you know that there is a so-called “flying” squirrel? All species of the "flying squirrel" living in Australia, ranging in size from 45 to 90 centimeters, live in trees. These squirrels acquired their name due to their movement characteristics. Their jumps from branch to branch resemble flight, and the squirrel itself during the “flight” becomes like a real glider. In fact, what squirrels do during their movements is not exactly flight: they simply make long jumps, jumping from one tree to another. Squirrels gliding between trees do not have wings, but they do have a flight membrane. This membrane in the "silver flying squirrel" (a type of flying squirrel) extends from the front legs to the hind legs; The flying membrane of squirrels is narrow and completely covered with long hairs resembling a fringe. Thanks to the stretched skin of the flight membrane, the squirrel can cover a distance of about 30 meters in one “flight”. There have been cases when, in six “flights” made in a row, they covered a distance of 530 meters.

When small animals do not move, they quickly lose heat and can freeze. Therefore, immobility, especially during sleep, poses a serious danger to their life. How do these animals survive? It turns out that all living beings in nature are protected from harmful influences environment. For example, squirrels wrap themselves in their fur-like tails and sleep curled up into a ball. This saves them from freezing while sleeping.

Squirrels are small mammalian rodents of the Squirrel family that are able to communicate with each other using different sounds and smells. Squirrels have a slender, streamlined, elongated body, fluffy long tail, long ears. The fur color is reddish-brown with a white belly. In winter, squirrels adapt to survive in new conditions and change the color of their fur to gray. They also use their tails as an alarm, the twitching of which alerts other squirrels to potential danger.
There are more than 265 species of squirrels around the world. The smallest are the African dwarf squirrels, which have a body length of only about 10 cm, while the Indian giant squirrel reaches a length of almost one meter.
When a squirrel is afraid and feels that it is in danger, it will primarily remain motionless. If he is on the ground, he will climb the nearest tree and rise to a safe height, and if she is already on the tree, he will try to press his body tightly against its bark.
Squirrels are very trusting animals and are one of the very few wild animal species that can be domesticated by humans.
In cold regions such as Russia, squirrels plan in advance how to survive in difficult conditions. winter months. They store nuts and seeds by hiding them in various places and return to them throughout the winter to replenish their energy reserves when food is scarce.
Squirrels are extremely intelligent creatures. For example, they may make fake food supplies to fool potential thieves, such as other squirrels or birds. And they make their real hiding places in another, safe place.
Squirrels make their homes in trees. They look like hollows or bird's nests and are made of branches and moss. Custom
but the squirrel cavity is the size of a football and is lined with grass, bark, moss and feathers for added comfort and insulation.
There are squirrels that can... fly. They are called "flying squirrels" and there are 44 species of these squirrels. Of course, they can't actually fly, we're talking about about gliding in the air using a special membrane that is located on the flying squirrel’s body and extends from the wrist to the ankles. This allows squirrels to naturally glide on long jumps, much like humans do with a parachute. Such sliding jumps can exceed 46 meters.
More than 200 species of squirrels are found throughout the world, with the exception of Australia.
Like other rodents, squirrels have 4 sharp front teeth that never stop growing, so their teeth are not worn down by constant gnawing. Squirrels live everywhere, from forested areas to city parks. Although they are amazing climbers, they often come to the ground in search of food, such as nuts, acorns, berries and flowers. They also eat bark, bird eggs or small chicks. Tree sap is a delicacy for some squirrel species.
Female squirrels give birth several times a year, giving birth to several blind baby squirrels at a time, which are completely dependent on their mothers for the first two or three months of life.
For a long time, people exterminated squirrels for their valuable fur, but thanks to high birth rates, the world's squirrel population remains large.

Our forests are rich in all kinds of living creatures, including rodents. However, among them it is not so easy to meet a flying rodent, namely the flying squirrel. She is the only representative of squirrels capable of jumping and flying in the territory Russian Federation. The ability of the squirrel to jump so masterfully between tree branches is due to the membranes between its front and hind legs.

External features

In appearance, a is very similar to the short-eared representative of the “red tails,” that is, squirrels. It is distinguished only by a wide leather fold with a wool cover. This is a kind of parachute and at the same time a load-bearing surface when jumping. In front, the fold is “attached” with a crescent-shaped tassel from the wrist to the forearm. However, it does not have membranes on the back, like its counterparts. The squirrel parachute does not connect to the tail. The flying squirrel has a fluffy and long tail.

Moreover, it is significantly smaller than an ordinary squirrel. The body length can be only 12 cm, and maximum size does not exceed 28.5 cm. At the same time, the tail is from 11 to 13 cm. What can we say about the feet, which are only 3 cm, the ears, the size of which is no more than 2 cm. And the weight of the flying squirrel is only 170 grams. The flying squirrel's head is neat and round, with a blunt nose and bulging black eyes. The shape of the eyes is due to their predominantly nocturnal lifestyle. Squirrel ears do not have tassels, and their legs are short. At the same time, the rear ones are longer than the front ones. The paws have short but rather sharp claws that curve inward. There are 4 pairs of nipples on the belly of the flying squirrel.

The fur of this flying representative of squirrels is very thick and soft. In common squirrels coat much rougher. These jumpers are also slightly different in their color. The fur on the upper part of the body is gray with a brown tint, but the belly is almost white. The tail is much lighter than the rest of the cover. In this case, the cover has some combing on the sides. The flying squirrel's cover is at its thickest and most beautiful in winter. But she sheds identically to her simple brothers - twice a year. The flying squirrel's eyes are tinted, or rather have a black outline.

Zoology includes 10 species of these flying animals, eight of which live on Russian lands.

Life cycle

The flying squirrel likes to settle in old mixed forests, characterized by the presence of aspen, birch and alder. Often settles near swamps and streams. Doesn't like jumper coniferous forests. But where there are birches and alders among the fir trees and pines, a squirrel can settle. The flying squirrel can inhabit and mountain ranges with existing forest thickets, as well as floodplain thickets of the north, ribbon forests of Siberia.

The squirrel representative is active all year round, but mainly at night or during twilight. If the animal is a nursing mother, then she can be seen even during the day. The flying squirrel generally spends most of its life searching for food. Similar to its ordinary counterparts, it settles in tree hollows. Moreover, these could be ready-made old houses of woodpeckers, squirrels, magpies. Sometimes the flying squirrel inhabits rock crevices. The squirrel puts forward only strict height requirements for them, namely from 3 to 12 meters from the ground. Very rarely, but still it happens that these animals settle in birdhouses near human settlements. The squirrel decorates its home with soft moss, leaves, and dry grass.

Flying squirrels are friendly, non-aggressive representatives of the animal world. At the same time, they can be friends with each other and even live in the same nest with other jumpers. Aggression can only be shown by a representative of squirrels protecting her offspring.

Thanks to its lethal device, the squirrel can glide from tree to tree located at a distance of 50-60 meters. In order to make a jump, the squirrel needs to climb to the very top, and then place its paws on the sides so that the hind ones are pressed to the tail. If you see such a flight from below, the squirrel’s shape will resemble a triangle. The flying squirrel can perform maneuvers thanks to the ability to control its membranes. The animal can change flight angles up to 90 degrees. And its long fluffy tail, in case of flight, functions as a braking device.

Before landing on the “seat,” the squirrel assumes a vertical position, and then clings to the tree trunk with all four limbs. Feeling support, the flying squirrel runs to the other side of the trunk and thus escapes the attack of birds of prey.

The presence of an animal in forest area very difficult to determine. Its color blends with the treetops, its paw prints are very similar to those of the common squirrel. However, a specific droppings that resemble an ant's clutch of eggs can give away.

The flying squirrel can be heard by its distinctive chirping sound.

The animal's diet is plant-based. These can be buds and foliage of trees. The jumper is very fond of young needles and their seeds. Especially pine or larch. The flying squirrel is a thrifty animal and stores seeds for the winter in its home. It also stocks alder and birch catkins. In summer, a representative of squirrels can eat mushrooms and berries. She does not refuse tree bark either. The flying squirrel's dining table is decorated with young willow, aspen, birch and maple bark. It is rare, but it does happen, that flying squirrels feed bird eggs or newly hatched chicks.

The squirrel produces offspring approximately 2 times a year. This can be from 2 to 4 baby squirrels. However, the reproduction of the jumper has been studied poorly. The animal's first litter appears in the spring (in April-May), the second in mid-summer. Flying squirrel cubs are born very small and helpless. They do not have fur, and begin to see only after two weeks. The baby squirrels begin to leave the nest only after a month and a half. On the 45th day they try to fly, and by the 50th day of their life they try to plan. During this same period, they switch to adult food and begin their independent existence.

The life of these flying creatures in conditions wildlife does not even reach the age of five. In captivity, their period of existence ranges from 9 to 13 years. This happens because natural enemies– owls, martens and sables, as well as due to other hazardous factors. For example, hunting it by humans.

Flying squirrel hunting

Unfortunately, there are very few such flying jumpers and hunting for them is limited. At the same time, its fur is not of great value. Hunting is interesting only as obtaining a valuable and unusual trophy. At the same time, the representative of squirrels is considered one of the oldest animals. Her remains are dated to the Miocene period.

Squirrel (Sciurus) is a mammal from the order of rodents, the squirrel family. This article describes this family.

Squirrel: description and photo

The common squirrel has a long body, a bushy tail and long ears. Squirrel ears are large and elongated, sometimes with tufts at the end. The paws are strong, with strong and sharp claws. Thanks to their strong paws, rodents can climb trees so easily.

An adult squirrel has a large tail, which makes up 2/3 of its entire body and serves as its “rudder” in flight. She catches air currents with it and balances. Squirrels also use their tails to cover themselves when they sleep. When choosing a partner, one of the main criteria is the tail. These animals are very attentive to this part of their body; it is the squirrel’s tail that is an indicator of its health.

The size of an average squirrel is 20-31 cm. Giant squirrels are about 50 cm in size, with the length of the tail being equal to the length of the body. The smallest squirrel, the mouse, has a body length of only 6-7.5 cm.

The squirrel's coat is different in winter and summer, since this animal sheds twice a year. In winter, the fur is fluffy and dense, and in summer it is short and sparse. The color of the squirrel is not the same; it can be dark brown, almost black, red and gray with a white belly. In summer, squirrels are mostly red, and in winter their coats turn bluish-gray.

Red squirrels have brown or olive-red fur. In summer, a black longitudinal stripe appears on their sides, separating the belly and back. The fur on the tummy and around the eyes is light.

Flying squirrels have membranes of skin on the sides of their bodies, between the wrists and ankles, which allow them to glide.

Dwarf squirrels have gray or brown fur on their backs and light fur on their bellies.

Types of squirrels, names and photos

The squirrel family includes 48 genera, which consist of 280 species. Below are some members of the family:

• Common flying squirrel;
• White squirrel;
• Mouse squirrel;
• The common squirrel or wecksha is the only representative of the squirrel genus on the territory of Russia.

The smallest is the mouse squirrel. Its length is only 6-7.5 cm, while the length of the tail reaches 5 cm.

Where does the squirrel live?

The squirrel is an animal that lives on all continents except Australia, Madagascar, the polar territories, southern South America and northwestern Africa. Squirrels live in Europe from Ireland to Scandinavia, in most of the CIS countries, in Asia Minor, partly in Syria and Iran, and in Northern China. These animals also inhabit the Northern and South America, islands of Trinidad and Tobago.
Squirrel lives in various forests: from northern to tropical. Most spends its life in trees, excellent at climbing and jumping from branch to branch. Squirrel traces can also be found near bodies of water. These rodents also live close to humans near arable land and in parks.

What do squirrels eat?

The squirrel mainly feeds on nuts, acorns, and seeds. coniferous trees: , larch, fir. The animal's diet includes mushrooms and various grains. Except plant food it can feed on various beetles and bird chicks. When the harvest fails and in early spring, the squirrel eats buds on trees, lichens, berries, the bark of young shoots, rhizomes and herbaceous plants.

Squirrel in winter. How does a squirrel prepare for winter?

When a squirrel prepares for winter, it makes a lot of shelters for its supplies. She collects acorns, nuts and mushrooms, and can hide food in hollows, burrows or dig holes on her own. Many squirrels' winter reserves are stolen by other animals. And squirrels simply forget about some hiding places. The animal helps restore the forest after a fire and increases the number of new trees. It is because of the forgetfulness of squirrels that hidden nuts and seeds germinate and form new plantings. In winter, the squirrel does not sleep, having prepared a supply of food in the fall. During frosts, she sits in her hollow, half asleep. If the frost is mild, the squirrel is active: it can steal caches, chipmunks and nutcrackers, finding prey even under a one and a half meter layer of snow.

Squirrel in spring

Early spring is the most unfavorable time for squirrels, as during this period the animals have practically nothing to eat. The stored seeds are beginning to germinate, but new ones have not yet appeared. Therefore, squirrels can only feed on the buds on trees and gnaw on the bones of animals that died during the winter. Squirrels living near humans often visit bird feeders in the hope of finding seeds and grains there. In the spring, squirrels begin to molt, this happens in mid-late March, and molting ends at the end of May. Also in the spring, squirrels begin mating games.

American flying squirrel- a representative of the squirrel family. The flying squirrel differs from the common squirrel in that it has membranes of skin extending from the front legs to the hind legs.

American flying squirrels lead night look life, so they have large eyes, like all animals that adapt to life in the dark.

Thanks to their special body structure, these animals glide from tree to tree, they don’t just jump, but literally fly, and they can perform complex movements, for example, landing at the same point with the bark they began their flight. The flight of these squirrels can be called aerobatics. In one flight, a squirrel can fly a distance of up to 60 meters. Thanks to this ability, American flying squirrels have advantages over many predators.

The American flying squirrel can feel confident in the air and on the surface of the earth because of its sickle-shaped bones that extend from its wrist. When the squirrel is in its normal position, the membrane is tightened, so it does not in any way interfere with the free movement of the animal.

During a jump, the American flying squirrel can coordinate its movements by moving its front legs and changing the angle of the membrane. Previously, it was assumed that a mobile and large tail helps the animals perform tricks, but over time it became clear that the flying squirrel’s tail is used only to slow down.

These squirrels live high in the crowns of trees, and they come down to the ground in rare cases. The animals are not picky about food; most often they feed on the go, and only the most delicious berries or nuts are hidden in hollows.

In winter, these reserves are needed, by the way, since flying squirrels sometimes wake up during hibernation, refresh themselves, and fall asleep again. The diet of flying squirrels consists of plant shoots, buds, seeds, lichens, fruits and mushrooms. In warm weather, proteins are added to the plant diet of insects, even spiders.

In summer, American flying squirrels prefer to lead a solitary lifestyle, but with the first cold weather they gather in groups of up to 25 individuals. With their bodies, squirrels warm each other during the day and during hibernation. IN hibernation The animals come out only when the temperature drops significantly, but not every winter they have to do this.

The enemies of American flying squirrels are large birds, mainly owls. If other birds of prey catch flying squirrels when they are in a tree, then owls can hunt them in flight, while owls rely on hearing, that is, they can hunt in complete darkness. American flying squirrels escape from predators by flying long distances.

After American flying squirrels mate, after 40 days the female gives birth to babies. Most often, one female gives birth to 2-3 cubs. The babies can fly after 2 months, while the female carefully monitors them; if the flight is unsuccessful, the mother helps the baby climb the tree again. The mother teaches the offspring to get food and teaches flight techniques. When the cubs are fully grown and master the technique of flight, they still do not leave their mother and remain with her until the next winter.
