    Appearance

    The ermine is a small animal of a typical mustelian appearance with long body on short legs long neck and triangular head with small rounded ears. The body length of the male is 17-38 cm (females are about half as long), the tail length is about 35% of the body length - 6-12 cm; body weight - from 70 to 260 g. Looks like a weasel, but somewhat larger in size.

    The color of the fur is protective: in winter it is pure white, in summer it is two-colored - the upper body is brownish-red, the bottom is yellowish-white. Winter color is typical for areas where at least 40 days a year there is snow. The tip of the tail is black throughout the year. Geographical variability in winter fur quality, summer fur color, and body size makes it possible to distinguish about 26 ermine subspecies.

    Spreading

    Lives in arctic, subarctic and temperate zones Eurasia and North America. In Europe, it is found from Scandinavia to the Pyrenees and the Alps, except in Albania, Greece, Bulgaria and Turkey. In Asia, its range extends to the deserts of Central Asia, Iran, Afghanistan, Mongolia, Northeast China, and northern Japan. AT North America found in Canada, on the islands of the Canadian Arctic Archipelago, in Greenland and in the north of the USA (except for the Great Plains). On the territory of Russia, it is common in the European north and in Siberia.

    Ermine

    Lifestyle

    Ermine is most numerous in the forest-steppe, taiga and tundra regions. Their choice of habitat is determined by the abundance of the main food - small rodents. As a rule, the ermine prefers to settle near water: along the banks and floodplains of rivers and streams, near forest lakes, along coastal meadows, thickets of shrubs and reeds. In depth forest areas comes rarely; in the forests it keeps old overgrown burnt areas and clearings, forest edges (especially near villages and arable lands); in dense forests he likes spruce and alder groves near the brooks. Common in copses, along steppe ravines and gullies. Avoids open spaces. Sometimes it settles near human habitation, in fields, gardens and forest parks, even on the outskirts of cities.

    Leads a predominantly solitary territorial way of life. The boundaries of the individual site are marked with the secretion of the anal glands. Plot sizes vary from 10 to 20 ha; in males, it is usually twice as large as in females, and intersects with their areas. Males and females live separately and meet only during the mating season. In hungry and low-fed years, stoats leave their territories and move, sometimes over considerable distances. Sometimes migration causes and mass reproduction rodents in neighboring areas.

    The ermine is active mainly in the twilight hours, sometimes it occurs during the day. In the choice of shelters, including broods, unpretentious. It can be found in the most unexpected places - for example, in haystacks, heaps of stones, in the ruins of abandoned buildings or in logs piled against the wall of a residential building. It also occupies tree hollows, often hiding in them during floods. Often the ermine occupies the burrows and nesting chambers of the rodents killed by it. The female lines her brood hole with the skins and hair of dead rodents, less often with dry grass. The ermine does not dig holes on its own. In winter, it does not have permanent shelters and uses random shelters - under stones, tree roots, logs. Rarely returns to the place of the day.

    The stoat is a good swimmer and climber, but essentially it is a specialized ground predator. Mouse-like rodents predominate in its diet, but unlike its relative, the weasel, which feeds on small voles, the ermine preys on larger rodents - water voles, hamsters, chipmunks, haystacks, lemmings, etc., overtaking them in burrows and under snow. The size does not allow it to penetrate into the holes of smaller rodents. Females hunt in burrows more often than males. Of secondary importance in the stoat's diet are birds and their eggs, as well as fish and shrews. Even less often (with a lack of basic food), the ermine eats amphibians, lizards and insects. Able to attack animals larger than himself (grouse, hazel grouse, white partridge, hares and rabbits); in famine years, he even eats garbage or steals meat and fish from people. When food is plentiful, the stoat builds up stocks, exterminating more rodents than it can eat. It kills prey like a weasel - biting through the skull in the occipital region. Ermine tracks down rodents, focusing on the smell, insects - on the sound, fish - with the help of vision.

    Ermine is a very mobile and dexterous animal. His movements are fast, but somewhat fussy. On hunting per day, it travels up to 15 km, in winter - an average of 3 km. On the snow it moves in jumps up to 50 cm long, pushing off the ground with both hind legs. It is an excellent swimmer and easily climbs trees. Pursued by the enemy, it often sits on a tree until the danger has passed. Usually silent, but in an excited state it chirps loudly, can chirp, hiss and even bark.

    young stoat

    The stoat is polygamous and breeds once a year. Sexual activity in males lasts 4 months, from mid-February to early June. Pregnancy in females with a long latent stage (8-9 months) - embryos do not develop until March. In total, it lasts 9-10 months, so the cubs appear in April - May of the next year. The number of cubs in litters ranges from 3 to 18, with an average of 4-9. Only the female takes care of them.

    Newborns weigh 3-4 g with a body length of 32-51 mm, are born blind, toothless, with closed auditory canals and covered with sparse white hair. At 30-41 days they begin to see clearly, and at 2-3 months they are indistinguishable from adults in size. At the end of June - in July, they already get food on their own.

    Females reach puberty very early, at 2-3 months, and males only at the age of 11-14 months. Young females (aged 60-70 days) can be productively covered by adult males, a unique case among mammals, contributing to the survival of the species. Average duration the life of an ermine is 1-2 years, the maximum is 7 years. The fertility and abundance of stoats fluctuate greatly, rising sharply during the years of abundance of rodents and falling catastrophically when they die out.

    Significance for a person

    The ermine is a common carnivore, but its numbers have now fallen sharply due to hunting, deterioration of food resources, destruction of habitats, etc.

    Ermine is an object of trade (fur is used as a finishing fur). Useful in the destruction of mouse-like rodents. Was unsuccessfully introduced to New Zealand to control the rabbit population; here it multiplied and turned into a pest that destroys the young and eggs of native birds, in particular, kiwi.

    Ermine in symbolism and heraldry

    The ermine was also a symbol of the personified Touch (one of the five senses).

    Ermine was the emblem ( impresa) Anna of Brittany and her daughter Claude of France - the wife of Francis I (-), therefore images of ermine can be seen in the royal palaces of France, for example, in Blois. The shield with ermines is depicted on the modern coat of arms and flag of Brittany, having switched to it from the banner of the Dukes of Brittany. There is a legend that one of the Dukes of Brittany Alain crooked beard(Alain Barbetorte), pursued by the Normans, was stopped by an overflowing river, muddy and muddy. At this time, the duke noticed an ermine running away from galloping horses and also stopped by the river. At the water's edge, the stoat turned sharply, preferring death to mud. Assessing the courage of the animal, Alain II shouted to his comrades-in-arms: “ Better death than a disgrace!”, and the enthusiastic Bretons turned to face the enemy.

    Ermine fur is not distinguished by high wear resistance and strength, while ermine is at the head of the hierarchical ladder in the world of furs. It has always been especially appreciated for its whiteness and softness. In addition, the ermine has always been known as a rarity - that is why it was endowed extraordinary properties. The amazing softness of ermine fur made the animal a symbol of one of the five senses - touch.

    It is not suitable for everyday wear. And if a fur coat made from his fur is worn in conditions big city, then she will not “stretch” more than one season. The wear resistance of ermine fur is approximately the same as that of a squirrel or a hare. However, none of the numerous furs can surpass the ermine in whiteness and softness. Apparently, these qualities allowed him to take a special place among other furs. And this place has most likely symbolic rather than utilitarian. It is also worth noting that products from this fur are usually sewn on a thin lining and are not insulated with batting or padding polyester, therefore, despite the beauty, it is quite possible to freeze in such a fur coat in severe frost.

    Cleanliness, along with pride, has long made this animal an exalted symbol for people of a noble family. His image was often used in the coats of arms of noble families with a motto that sounded something like this: "It is better to die than to be tarnished." It sounds quite chivalrous and in the spirit of medieval customs and traditions. Ermine fur trimming of clothes or headdresses of nobles, judges and masters symbolized moral or intellectual purity. Ermine fur on clothes is a sign of royal dignity, secular and religious nobility. Sometimes Christian holy virgins of noble birth, for example, Saint Ursula, were depicted in clothes made of ermine fur.

    - a valuable fur-bearing animal of the weasel family.

    Ermine is a small animal of typical mustelian appearance with a long body on short legs, a long neck and a triangular head with small rounded ears. There is a poorly developed swimming membrane between the fingers. The eyes are small and shiny, the mustache is long. The stoat has 34 small sharp teeth. The feet are densely pubescent below; in the winter fur, corns are not visible on them.
    The body length of the male is 17-38 cm (females are about half as long), the tail length is about 35% of the body length - 6-12 cm; body weight - depends on the range and gender (90-350 g). Stoats living in the north are smaller than those living in Europe. Males are usually 50% heavier than females.
    Usually silent, but in an excited state it chirps loudly, can chirp, hiss and even bark.
    The color of the fur is protective: in winter it is pure white, in summer it is two-tone - the upper body is brownish-red, the bottom is yellowish-white. The tip of the tail is black throughout the year. Winter coloration is typical for areas where at least 40 days a year there is snow. Geographical variability in winter fur quality, summer fur color, and body size makes it possible to distinguish about 26 ermine subspecies.
    The winter fur is thick, silky and close to the body. The tail is long (1/3 of the body length). The density of the coat remains constant in summer and winter, only the length and thickness of the hairs change.
    Ermine is widely distributed in the Northern Hemisphere - in the Arctic, subarctic and temperate zones of Eurasia and North America. In Europe, it is found from Scandinavia to the Pyrenees and the Alps, with the exception of Albania, Greece, Bulgaria and Turkey. In Asia, its range reaches the desert Central Asia, Iran, Afghanistan, Mongolia, Northeast China and northern Japan. In North America, it is found in Canada, on the islands of the Canadian Arctic Archipelago, in Greenland and in the north of the USA (except for the Great Plains). On the territory of Russia, it is common in the European north and in Siberia.
    Was brought into New Zealand to control the rabbit population.
    Ermine is most numerous in the forest-steppe, taiga and tundra regions, as well as in the mountains, in the Pamirs and in the Himalayas, rising to a height of 3.5-4 thousand meters. The choice of their habitat is determined by the abundance of the main food - small rodents. As a rule, the ermine prefers to settle near water: along the banks and floodplains of rivers and streams, near forest lakes, along coastal meadows, thickets of shrubs and reeds. It rarely enters the depths of forests; in the forests it keeps old overgrown burnt areas and clearings, forest edges (especially near villages and arable lands); in dense forests, he likes spruce and alder groves near the streams. Common in copses, along steppe ravines and gullies. In the mountainous areas of Siberia, it reaches the zone of loaches, settling among stony placers with colonies of pikas, as well as on alpine meadows where snow cover is low. In forest areas, ermine often lives near settlements or even within their borders - in stockyards and slaughterhouses, in warehouses and other buildings.
    Neither low temperatures, nor high snow does not interfere with the normal life of the ermine. It feels worse during spring floods, as well as during winter thaws, when the snow is strongly compacted and prevents the animal from hunting for small rodents.
    It leads a predominantly solitary territorial way of life, lives quite sedentary, at least in winter, with a good supply of food. Individual territories in floodplains are usually extended along the banks, covering an area of ​​8-30 hectares; on terraces above the floodplains, their size increases to 50-100 hectares. On each territory, separate fattening areas are allocated, where the animal returns for hunting every 2-3 days and “passing”, where it does not stay for a long time. The network of individual territories, their boundaries are redrawn in the autumn-winter period, when the younger generation develops habitats, and some of the old individuals become victims of larger predators and hunters.
    With a lack of food, the animals are rather weakly attached to certain territory, mostly roam. The change of habitats is most pronounced in low floodplains: with the onset of floods, stoats concentrate on low ridges or migrate to neighboring forests at a distance of several kilometers. In many places, they often spend the winter near the outskirts of settlements, where mouse-like rodents move in large numbers. In the mountains, predators make seasonal vertical movements, which are generally characteristic of mountain animals.
    The ermine, like other small mustelids, usually lives in the burrows of rodents eaten by them. The predator itself digs with great difficulty: one married couple, who lived in an aviary, where there was no suitable shelter, dug a hole in the ground only 15 centimeters long in a week. Ready-made ermine hole with several burrows, in some of them the owner arranges latrines; there are several latrines near the burrow. Less commonly, the ermine settles in heaps of hay or straw, hollow old stumps, under dead wood or in piles of stones, in settlements makes shelter in abandoned buildings. A spherical nest is made from dry grass and leaves, wool and scraps of skins of voles eaten by a predator, bird feathers.
    Ermine is active mainly in the morning and evening twilight hours, when voles are most active.
    Ermine is a very mobile and dexterous animal. His movements are fast, but somewhat fussy. Due to the pubescence of the paws, the animal easily moves through the snow with jumps up to 50 cm long, pushing off the ground with both hind legs; however, if it snows the cover is deep and soft, he prefers to “dive” into it and move in the snowy passages. On hunting per day, it travels up to 15 km, in winter - an average of 3 km. In winter, at temperatures below -30 °, he generally tries not to leave the shelter. In case of pursuit, it quickly climbs bushes and trees, sometimes up to 15 meters high. The stoat swims well, during the spring flood it can overcome water spaces up to a kilometer long. When protected or frightened, the animal releases a sharp-smelling secret of the prianal glands; the same odorous liquid, in addition to urine, marks an individual area. (ads3)
    The stoat swims and climbs well, but is essentially a specialized land predator. Mouse-like rodents predominate in its diet, but unlike its cousin, the weasel, which feeds on small voles, the ermine preys on larger rodents - water vole, hamster, chipmunk, haystacks, lemmings, etc., overtaking them in burrows and under the snow. The size does not allow it to penetrate into the holes of smaller rodents. Females hunt in burrows more often than males. Birds and their eggs are of secondary importance in the ermine diet, and t also fish and shrews. Even less often (with a lack of basic food), the ermine eats amphibians, lizards and insects. Able to attack animals larger than himself (grouse, hazel grouse, white partridges, hares and rabbits); in famine years, he even eats garbage or steals meat and fish from people. When food is plentiful, the stoat builds up stocks, exterminating more rodents than it can eat. Prey kills like a weasel - biting through the skull in the occipital region. Ermine tracks down rodents, focusing on the smell, insects - on the sound, fish - with the help of vision.
    The hunting path of the stoat is winding, with frequent returns and crossings of its own tracks. Often on a path that is no more than a kilometer in a straight line, he manages to wind paths 2-3 kilometers long. Only in areas where there is obviously no food, the predator passes without delays and dives into the snow. In a straight line, the animal also crosses vast open spaces fields, frozen lakes and rivers. In search of food, the animal, like a setter dog, scours the “shuttle” along the arable land, holding its tail up, its black tassel is in constant motion. Sometimes he stops and rises with a “column” on his hind legs - looks around. Diving into the snow, he reappears after 10-15 seconds and continues to draw whimsical loops on the snow-white surface.
    With an abundance of food, the predatory reflex causes a hungry stoat to kill rodents much more than he can eat - up to 8-10 mice and voles per day. However, this reflex fades with saturation, so that in the following days, even if the prey does not decrease, the predator kills only 2-3 mice per day, which it eats almost entirely. Prey that is not eaten immediately, he often hides until the worst of times: sometimes up to 20-25 voles are found in his pantries.
    This small predator very brave; in a hopeless situation, he risks throwing himself even at a person. To natural enemies ermine include rufous and gray fox, martens, ilka, sable, American badger, predator birds; occasionally it is caught by ordinary cats. Many stoats die from infection with the parasitic nematode Skrjabingylus nasicola, which lives in the frontal sinuses; its carriers are obviously shrews.
    The stoat is polygamous and breeds once a year. Sexual activity in males lasts 4 months, from mid-February to early June. Pregnancy in females with a long latent stage (8-9 months) - embryos do not develop until March. In total, it lasts 9-10 months, so that the cubs appear in April - May of the next year. cubs in a litter 5-8, but sometimes up to 18, on average 4-9. Only the female takes care of them.
    Most often, the female stoat is a very caring mother. In the first days after the birth of offspring, she rarely leaves the nest, warming her cubs with her warmth, unable to maintain a constantly high body temperature. When it gets cold, the mother plugs the inlet with a piece of bedding or the carcass of a killed vole. On hot days, on the contrary, she sometimes takes her puppies out of the stuffy nest and lays them down on a cooler bed of grass and leaves. From the discovered brood nest, the ermine drags the cubs to another shelter: she grabs each child in turn, even if it is only half the size of the mother, by the scruff of the neck and skips to a new place, the cub curled up can only silently pound on bumps and snags. If a predator or a man approaches the hole with a brood, the female screeches furiously, jumps on him, protecting her offspring.
    Newborns have a mass of 3-4 g with a body length of 32-51 mm, are born blind, toothless, with closed auditory canals and covered with sparse white hair, and spend the first days huddled together - the so-called children's "coupling reflex" appears, which contributes to the preservation heat. Cubs grow more slowly than other small mustelids: their eyes open only at the age of one month, and at the age of about 40 days they begin to respond with a voice (“chik”) to the appearance of a threat. As soon as they see the light, the cubs become mobile and aggressive, they try to eat meat with great eagerness, they mess with each other for a long time. They begin to leave the nest in the second month of life. At first, the mother prevents this in every possible way and, grabbing the cubs by the “mane” with her teeth, tries to drag them back. At this time, milk feeding stops. Family life lasts 3-4 months, the disintegration of broods and the beginning of the resettlement of young occur in the middle or end of summer. In areas where stoats are actively hunted, only a few of them live to the age of two, while in captivity the animals live 5-6 years.
    Females reach puberty very early, at 2-3 months, and males only at the age of 11-14 months. Young females (aged 60-70 days) can be productively covered by adult males, a unique case among mammals that contributes to the survival of the species.
    Ermine belongs to the common predators. But because of the very valuable fur, its numbers have fallen dramatically. Winter white skin with a black tail is still in old times went to fur coats, hats, mantles of noble persons. This animal is of great benefit, destroying small rodent pests. So, in the 50s, a complete ban on ermine fishing was specifically introduced on Sakhalin in order to cope with excessively breeding voles.
    Was unsuccessfully introduced to New Zealand to control the rabbit population; here it multiplied and turned into a pest that destroys the young and eggs of native birds, in particular, kiwi.

    The ermine is a valuable fur-bearing animal. In the past, its snow-white fur with black-tipped tails was considered a symbol of purity and purity and was used to line royal and judicial robes.

    In summer, brown-brown upperparts, white or yellowish underparts; in winter, the color is pure white (some Caucasian animals do not turn white in the winter). It differs from the weasel and solongoy in all seasons by the black tip of the tail. The trail is elongated, about 2.5*2 cm, the length of the jump is 30-40 cm.

    It lives everywhere, except for some islands, the Amur Valley and Southern Primorye, in the same landscapes as the weasel. In the tundra and dry steppes it is rare and inhabits only thickets of shrubs and the banks of water bodies, and in the taiga and forest-steppe it is more common than weasel. There are especially many ermines on the Lower Ob. Extremely rare in the Caucasus. Sometimes it settles in taiga huts and settlements, but in big cities it is found only where there are especially many rats - in landfills, vegetable bases.

    It feeds on rodents, less often on other small animals, carrion, and berries. On occasion, it follows the tracks of large predators, picking up the remains of prey. Larger than the weasel, the size does not allow it to penetrate the holes of small rodents, so the stoat preys on medium-sized species, primarily on water rat. Active mainly in the morning and evening. Gon in the summer, pregnancy with a latent stage - the embryo begins to develop only a few months after fertilization. Stoats have developed an amazing adaptation aimed at increasing the rate of reproduction. Newborn females, still blind and naked, already attract adult males and are often fertilized almost immediately after birth. As a result, they can bring offspring as early as next spring.

    Ermine - valuable fur animal. In the past, its snow-white fur with black-tipped tails was considered a symbol of purity and purity and was used to line royal and judicial robes. There was a case in England in the 17th century when an accused, a furrier by profession, protested against a court decision on the grounds that the judge was wearing a robe of fake ermine. The verdict was declared invalid. Now the stoat is hunted mainly in the North, primarily in Yakutia. Unfortunately, its strength is different reasons decreased somewhat in recent decades, especially in central and southern regions. Ermine - main enemy water rat, a dangerous agricultural pest.
