And with the money that the gold-toothed seducer offered, you could buy a lot more, and even a bicycle, so that on vacation on Ilek go swimming.

I remember one of those days we went to the river Ilek, then still full-flowing, not polluted by discharges of factories.

The river of his childhood perished - Ilek, with numerous beautiful beaches, the tulip fields disappeared behind its high steeps, dragonflies, butterflies, grasshoppers hatched clean in the meadows, dried up and turned into swamps of the lake with crucians and lilies, with duck hunting in autumn.

The close smell of water hit the half-open window and reminded Ilek-- the river of his childhood.

During my childhood Ilek He was not only a breadwinner and drinker, but also the beauty of the region, dozens of generations grew up on its shores, thousands and thousands dream of him.

The American, or otherwise it is called the black-footed ferret, belongs to the predatory representatives of the weasel family. One of the features in which he differs from his other ferret relatives is his small body length and little weight. That is, with a weight of one kilogram, or even less, this individual rarely exceeds 45 cm in length.

Appearance description

The coat color is usually yellow-brown and darker on the back, while the tip of the tail and paws are black. Interesting fact that by 1937 of the last century, this subspecies of ferrets was almost completely destroyed in Canada. But, starting in 1980, its numbers began to be gradually restored through artificial breeding. After that, bred in specially created conditions, individuals were gradually returned to their former habitat. Despite the fact that today the number of trochees has increased significantly, it still, starting from 1967, continues to be listed in the Red Book. North America as an endangered species.

Habitat

Females are less active than males. And in winter, their activity is completely reduced, compared with summer period. They begin to hunt less due to the difficulty of moving through the snow cover, and more often prefer to remain in burrows, feeding exclusively on their reserves.

Ferrets are loners. They lead an isolated way of life, practically do not contact their relatives, except, probably, only for the "marriage" period.

What do they eat

Usually, on average, a ferret consumes 50 to 70 grams of meat per day. At the same time, most often the diet of American ferrets is made up of rodents, less often - small birds and insects. But their main delicacy is ground squirrels, or as they are called in those parts - steppe dogs. To get enough, one ferret needs to eat about 250 ground squirrels a year. The very same typical colony prairie dogs lives on an area equal to about 50 hectares of steppe terrain.

In the middle of the last century, mass poisoning and extermination of dogs began in the United States in connection with the development of land by local farmers. Which was the main reason for the active extinction of ferrets. After all, the latter were actually left without food.

Conditions of life and reproduction

In early spring, individuals of this species, as a rule, begin the breeding season. After that, after about 1.5 months, cubs are born, the number of which rarely exceeds 5 pieces. This feature is unique to American ferrets, in contrast to their forest and steppe relatives, whose litter can exceed 8 puppies.

AT wild nature animals do not live long - up to about 4 years. What can not be said about their relatives raised in captivity - their life expectancy can reach as much as 9 years. Whereas they reach puberty by the age of one year.

Appearance

The American ferret, like most of the weasel family, has an elongated body on thin, short legs, and an elongated muzzle. And a 15 cm fluffy tail. They have an intricate color: yellowish-brown at the ends, closer to the roots it becomes white, and the paws and the tip of the tail are black. Also, black fur frames the eyes, resembling “glasses”, which act as an additional disguise. Males are larger than females. Like skunks, ferrets are capable of emitting a foul odor to protect themselves, though it is not as strong as a skunk's.

Measures for protection and reproduction

Helping the black-footed ferret not to disappear from the face of the earth Federal and state agencies of the USA together with private farmers. They spend everything possible actions for their breeding and introduction into the wild.

For the people themselves, in this case farmers, ferrets are beneficial by eating harmful prairie dogs, thereby helping to control their population. The latter are especially dangerous for livestock because they are carriers of various infections, one of which is bubonic plague. So is the harm - a large number of holes and tunnel systems belonging to ferrets and dogs often cause injuries to livestock, which now and then gets into them.

Black-footed ferret, Black-footed Ferret: Mustela nigripes Audubon & Bachman, 1851. Other names: American black-footed ferret

Range: originally the range of the black-footed weasel occupied the eastern and southern regions Rocky Mountains, the territory of the Great Plains from Albert and Saskatchewan, to Texas and Arizona (USA).

The American black-footed ferret has a long neck and a slender, sinewy body, with very short legs.

Color: The smooth fur of the black-footed ferret has a yellowish color; there are black spots on its muzzle, the tip of the tail and its legs are also black.

The American [black-footed] ferret is 46 - 60 cm long, including 13 - 15 cm bushy tail. Weight: It weighs 0.7 - 1.1 kg, with males weighing slightly more than females.

Lifespan: Ferrets usually live in the wild for about 3 - 4 years (the oldest lived at least 8 years) and 8 - 9 years in captivity (the oldest individual was at least 11 years old).

Voice: The American black-footed ferret is a very vocal animal. He screams loudly when disturbed, frightened or excited. In such a situation, he lets out several loud cries, interrupted by low hissing notes. Male black-footed ferrets "chuckle" when contacting a female during the rutting season, and the cubs make very quiet squeaky sounds.

Habitat: The American black-footed ferret is commonly found in prairie, low to medium height grassland, forming an association with prairie dogs.

Like other weasels and ferrets, the black-footed ferret easily moves around the territory in search of its prey, climbing through treeless spaces even high into the mountains. Individual individuals were found at an altitude of 3000 m above sea level, and another animal was found drowned in Lake Morena, Colorado [USA], located at an altitude of 3125 m.

The North American Prairie is one of the most endangered ecosystems on earth - perhaps even more endangered than the South American rainforest or the old forests of the American Northwest. The prairie plains of North America began to form about 20 million years ago, but in some areas, up to 99 percent of the prairie has been destroyed in just the past 125 to 150 years.

The area known as the Great Plains was once the largest field on earth and covered most the continental US along with parts of southern Canada and northern Mexico. The prairie stretched from the Rocky Mountains in an eastward direction for over 800 miles, and extended over 3,000 miles from north to south. The plains were created from sedimentary rocks washed out of the Rocky Mountains over millions of years, which were formed from silt, sand and clay. The Rocky Mountains also cut off access to the streams humid air from Pacific Ocean, creating a drier climate on the continent that favored the development of grasses over trees.

Enemies: Habitat loss is the main reason why black-footed ferrets have been on the brink of near extinction and why it remains a major threat to the species today. Conversion of fields and grasslands to agricultural use and a widespread prairie dog eradication program have reduced the black-footed ferret's habitat to less than 2 percent of what it used to be. Remaining habitats are now fragmented, associated with prairie dog colonies, separated by large expanses of cropland and human structures. Diseases, including plague (affecting both black-footed ferrets and their prey, prairie dogs), as well as poisoning and shooting, also remain potential threats.

The American Black-footed Ferret is commonly found in prairie dog colonies, which make up the absolute majority of their diet. In nature, prairie dogs make up 90% of the black-footed ferret's diet.

The black-footed ferret also eats gophers, other small rodents, American rabbits and birds.

A ferret typically eats over 100 prairie dogs in one year, and on this basis, scientists have calculated that over 250 prairie dogs are needed to support one family of black-footed ferrets for one year.

It has been estimated that about 40 - 60 ha of prairie dog colonies are needed to support a single black ferret. The black-footed polecat usually surveys an area up to 100 ha during a 3 to 8 day period in winter.

The black-footed ferret is a secretive animal, leading primarily a nocturnal lifestyle. It has well developed external bodies senses: acute hearing, sensitive sense of smell and good vision.

The American black-footed ferret is extremely dependent on the prairie dog. Due to feeding mainly on prairie dogs, the black-footed ferret spends most of its life in its colonies. It spends up to 99% of its time in prairie dog burrows, usually being only a few minutes each day. earth's surface. In burrows he sleeps, gets his food, avoids predators and bad weather, and here he brings out his young. For rest and sleep, the black-footed ferret occupies an underground hole made by a prairie dog.

Its long, slender body allows it to easily enter burrows to find prey while prairie dogs are sleeping. This reduces the risk of damage to the ferret, as it attacks prey of the same size as itself.

Males are more active than females. The black-footed ferret does not sleep in winter, but the amount of time of activity decreases significantly, as does the area of ​​the surveyed territory. In winter, in cold snowy weather, the black-footed ferret can remain inactive for long periods, up to 6 nights and days, remaining in a burrow in which it subsists on previously stored food.

When the black-footed ferret travels across the surface of the earth, it moves in a series of leaps or a slow gallop. He can normally move at a speed of 8 - 11 km / h. Biologists tracked a black-footed ferret that traveled 10 km in one night, during which time it examined more than 100 prairie dog holes. The distance covered by males is almost twice that of females.

social structure: The black-footed ferret leads a solitary life, except for the mating season, and at the same time, males apparently do not help raise and feed the young.

The black-footed ferret uses scent marks to communicate with its compatriots, using the secretion of the anal glands for this purpose. It marks its territory by applying the odorous secretion of the gland to rocks, soil and vegetation.

The population of black-footed ferrets consists of approximately 67% of young animals, and 33% are adults.

A study of the wild population has shown that the average ferret density in favorable habitats is approximately 1 animal per 50 ha of prairie dog colonies. The average distance between two prairie dog towns occupied by the black-footed ferret was 5.4 km. Adult ferrets occupy an area with a diameter of approximately 1 - 2 km.

Reproduction: The young emerge from the burrow in July. late summer, females increasingly leave their offspring alone in the burrow during the day, and gather them together at night to hunt together. Young ferrets begin to hunt on their own only from September or October, when they leave their mother and become independent and solitary.

Young males settle over greater distances, generally up to 10 - 15 km, while young females often remain close to the mother's territory.

Season/Breeding Period: Mating usually takes place in March and April.

Puberty: Both males and females become sexually mature in their first year of life. The peak reproductive period for males and females is around three to four years of age.

Pregnancy: 41 - 45 days (about 7 weeks)

Offspring: the female brings an average of 3 - 4 young, sometimes in a litter with artificial maintenance, there are up to 9-10 puppies. In nature, litter size in South Dakota averaged 3.5 (varied: 1 - 5); in Wyoming averaged 3.3 babies.

The black-footed ferret is a naturally effective prairie dog population regulator.

The black-footed ferret is listed in the Sites Convention Appendix as a species endangered and in Appendix II of the International Trade Agreement (a list of species prohibited from commercial trade).

Antipathy towards prairie dogs is pronounced among some populations, including ranchers and many workers. Agriculture. Therefore, from the 1920s to the 1960s, the US government sponsored intensive programs to eradicate the prairie dog from the Great Plains states using poison and plowing prairie dog settlements (in order to prevent damage to agriculture and occupation). cattle animal husbandry). For example, the area occupied by prairie dog cities in Kansas was reduced by 98.6%, the black-footed ferret was apparently an unintentional victim of the prairie dog eradication campaign. Even in the 1990s, federal agencies authorized and subsidized the annual eradication of 80,000 hectares of prairie dog colonies.

Thus, the black-footed ferret experienced a dramatic decline in numbers during the first half of the 20th century. She hasn't dated since 1937. In the late 1970s, he was thought to have disappeared from both countries. However, in 1981, a black-footed ferret colony was found in Wyoming, USA.

The first group of captured ferrets all died because a number of them were infected in nature with the causative agent of rabies. This led to the discovery that canine rabies was responsible for the rapid decline in the ferret population in Meeteetse. At this point, all 18 remaining ferrets were captured, vaccinated, quarantined, and sent to a breeding center. As a result of the black-footed ferret breeding program, by 1991 the captive population increased to 311 animals and 49 animals were released back into the wild. They now live in seven sites where the species has been reintroduced, including sites in Montana, Wyoming, Arizona, South Dakota and along the Colorado-Utah border, as well as in Chihuahua, Mexico.

In 1998, the number of offspring of the black-footed ferret, bred in six zoos and one government breeding center for this species, gave results that surpassed all previous ones with a total of 425 born of which 321 survived to the age of the end of mother's milk feeding.

Status and Trends: 1960s - 1994: endangered species; 1996 - 2004: extinct in nature (IUCN 2004). Currently, the black-footed ferret is found in Canada and the United States.

Population Estimates: 1920s: There may have been approximately 800,000 individuals. 1984 - 128 individuals, in 1996 and it now manages 240 (90 males and females), 2005 - about 500 individuals. There are currently approximately 1,000 black-footed ferrets in captivity.

In a year, one individual eats more than 100 prairie dogs, and more than 250 dogs are needed for one ferret family.

Behavior: leads a nocturnal lifestyle. Hearing, sight and smell are well developed. The species is highly dependent on prairie dogs. Almost all the time (up to 99%) he spends in their holes. In the area of ​​these colonies, he rests and sleeps, immediately gets his own food, avoids predators, bad weather and feeds offspring.
Males are more active than females. AT winter period the activity of black-footed ferrets decreases, as does the area of ​​the surveyed territory. On cold and snowy days it remains in the hole, feeding on its reserves.

Population/conservation status : The species is listed in Appendix II of the CITES Convention.
The main threat to the species is habitat loss (the conversion of fields and meadows to agricultural use and a widespread prairie dog eradication program has reduced the black-footed ferret's habitat to less than 2% of what it used to be). The American black-footed ferret is listed in the International Red Book: in 1960-1994. as endangered, 1996-2004 like disappearing in nature.
The ferret is currently found in Canada and the USA. The population of the species in 2005 consisted of about 500 individuals in nature and about a thousand in captivity.

The red book is full various types animals that are on the verge of extinction or disappeared altogether. Among them is the American Black-footed Ferret. This animal belongs to the mustelid family and, through the fault of poachers, has practically disappeared from the mainland. Thanks to the efforts of livestock breeders and local historians, Black-footed ferrets are already gradually restoring their population.

This is a very unusual animal both in color and in habits. His habitat and historical homeland- North America, where they are now actively grown. After being listed in the Red Book, the trochee began to be actively protected, and now any hunting for these animals is strictly punishable by law.

Description of American Blackfoot ferrets

The description of this type of ferret is worth special attention, because this breed has remarkable appearance features.

Distinctive features of Black-footed ferrets:

• The ferret has a long elongated body and neck, short and thick legs.
• The fur color of such animals is yellow-brown, darker on the back, and generally turns black towards the tail and paws (hence the name Black-footed American Ferret).
• A distinctive feature of the trochee of just such a breed is the so-called mask around the eyes (the color of the coat around the eyes of such animals is black).
• This type of ferret has large, rounded eyes that stand out against a white muzzle, where a black nose is also visible.
• The shape of the claws is pointed and slightly curved.
• The average weight of the female is in the range from 650 to 850 g, and the male can reach a mass of 1200 g.
• According to average indicators, the length of the calf in the described trochees is 350-600 cm, and according to the statistics of the female, it is always 10% less than the male representatives of this breed.

So expressive appearance leaves almost no one indifferent, which is why the skins of such animals are very much appreciated by hunters, although it is important to remember that now the Red Book contains the name American Black-footed Ferret, which automatically prohibits any activity aimed at depopulating the species.

American Black-footed polecats can be seen in wildlife reserves in North America. Or, if there is no opportunity to visit another continent, anyone can easily admire the photo of the Black-footed Ferret on the Internet.

Habitat

The black-footed ferret is an animal that was quite common until the beginning of the last century. The historical range of animals is the territory stretching from the south of Canada to the north of Mexico. For North America, this species is the only indigenous representative. Today, a tourist can observe the described polecats only in 3 territorial limits in the northeast of Montana, in the western part of South Dakota and in the southeast of the state. Wyoming. In addition to natural habitats, people can also see how the American ferret behaves in a zoo or nature reserve. In places of natural settlement, the population was restored. Recovery continues to this day.

Knowing the range of these animals, it is quite simple to guess about their living conditions:

• Steppe and hilly terrain in the expanses of North America.
• haven for American polecat often becomes an abandoned hole left by a prairie dog (in such holes it is easier for animals to make tunnels and hide from hunting).
• For obtaining food, one representative of this breed, according to average indications, needs a lot of space: within 40-45 hectares.
• Females with offspring require even more space to survive: up to 55 hectares.
• One male can introduce several females into the habitat at once.

The black-footed ferret is a freedom-loving creature that needs a large amount of free space for a normal existence. Such animals do not tolerate restrictions, and even in zoos they always get a large territory.

No less interesting is the life of such animals: the lifestyle they lead should be given special attention. The attitude towards the marten family has left its mark on the habits and habits of the trochee.

Lifestyle and nutrition

The American ferret is predominantly nocturnal. This is a predatory animal, the activity of which occurs at night. Having a good sense of smell and even sharper hearing, representatives of this breed can easily navigate without sunlight. The black coat allows them to remain less visible.

During the hunt, representatives of this species climb into the burrows of their victims (small rodents), where they deal with their prey, and then they also settle for a while. They are fast and agile, thanks to the structure of their body.

The black-footed ferret is a solitary animal. He does not try to get into the flock and only during the breeding season creates a pair.

With all these qualities, the American ferret is a friendly and non-aggressive animal towards representatives of its own species.

The diet for such animals consists of a large number options:

• small rodents hiding in burrows;
• large insects;
• small birds, etc.

These cute at first glance animals are still predators. According to the statistics of livestock breeders, one black-footed ferret consumes about 100 prairie dogs during the year. In the reserves they are specially fed, and the cubs are fed with milk. In the 80s of the last century, all animals kept in captivity were released into a free habitat in order to renew the population and save the species from extinction.

Conclusion

The American ferret is a rare, but beautiful and unusual animal. The fact of entering into the Red Book only gives this breed an aura of mystery and makes it even more interesting for others and tourists.
