Within Kazakhstan is only the western part of the range red-squirrel. This zverok distributed in the following administrative regions of Kazakhstan: in northern Kustanai region, in the North-Kazakhstan, Kokchetav-tion in northern Tselinograd, Pavlodar, Semipalatinsk, in the northern part of the EastKazakhstan region. The northern boundary of its distribution is outside the country.
Areas with the largest number of red-squirrel are the areas of the right bank of the Irtysh (Pavlodar area). A large concentration of rodent burrows (40-140 1 ha) noted in Pavlodar and Máximo Gorki-areas (Tolebaev, Read more [...]
In nature food clawed ground squirrels studied by us by eating the inspection or fresh kopanok during search technique and getting them to feed.
Direct observations in the habitats of animals found that in Southern Balkhash this gopher digs and eats roots following plants: sand sedge (Carex physodes), broomrape (Orobanche lutea), bluegrass (Poa bulbosa), white crowfoot (Haloxylon persicum), Ephedra (Ephedra lomatolepis).
Gopher digs most succulent roots sand sedge. In shoots of the plant, he breaks the dry outer leaves and eats succulent centerpiece.
After the rains, due to the Read more [...]
Synonyms: Spermophilus brevicauda, Spermophilus intermedius.
Kazakh name: sarshynak.
In Pushnikov: common ground squirrel.
Notes on taxonomy. The systematic position of the mean, or blednohvostogo gopher can not be considered definitely established.
In 1843, FF Brandt almost simultaneously described two species of ground squirrels: Citellus brevicauda - From the Zaisan basin and S. intermedius - A copy of which were taken in the vicinity of Lake. Balkhash. In the future, due to the lack of mass collection of materials on ground squirrels Balkhash and related sites enters Read more [...]
Terms of bedding and wake squirrels depend on a variety of reasons - geographical, climatic and landscape (topography, slope exposure in the mountains, etc.).
Sleep long-tailed ground squirrel in the Altai starts in September - October. Sometimes squirrels occur much earlier because of the burning of vegetation on the slopes of the southern exposure. So, in 1948, most of the adult squirrels did not appear on the surface, starting from the second half of August. From hibernation in that area squirrels wake up in late March - mid April. Consequently, the duration of hibernation of ground Read more [...]
Behavior. Clawed gopher active all year round. By type of mobility this animal similar to other life forms desert rodents - jerboa. Tropleniya method after rains revealed that he goes in search of food from the holes at a distance of 800-1000 m Disturbed and persecuted individual person can run up to 20 - 30 min and make transitions to 3 km. Surface activity of these rodents in the winter, due to foraging, almost stopped. The lack of food supplies for the winter causes them to enter the period of apprenticeship in the most adverse weather, so the difference in the daily activities in different Read more [...]
A characteristic feature in the distribution of long-tailed ground squirrel is busy Slight them land that emerges most clearly in a highly mosaic mountain landscape. He settles micropopulations in areas with relatively gentle slopes that are most often confined to the upper reaches of the rivers. The settlements are often separated by insurmountable obstacles for the animals. Thus, in the upper river. Greater Baskaev summer of 1962 we were able to find large populations of ground squirrels in only two places - in the tract Sursay Taukensay and held a 10-15 km from each other and separated by Read more [...]

Top of the head is colored like the back. Colouring sides grayish-yellow, abdomen - light, ocher-yellow. Throat lighter colored belly. Coloring the upper side of the tail of sand-yellow, the bottom light rusty. Pre-end rim of the tail is black. Limbs pale ocher. By the end of molting fur thins, volosyanoypokrov

Rodent the size of a squirrel. Adult weight of 600-800 g; length body 255-295, 75-100 tail, hind foot 60-68 mm; fingers limbs are long and thin. On the back of the longest limb second to fourth fingers at the front - the second and third. Claws up to 15 mm. Eight nipples, no cheek pouches (viewed 20 adults from Southern Balkhash).
Winter fur is long (up to 15-18 mm) fluffy, soft with a thick undercoat. Spin straw-yellow in color, with no clear weak spot. The summer fur is very rare, short and without underfur. Hair tight and snug against the skin. In summer fur guard hairs under a microscope Read more [...]
By catches, tropleny and visual observations in the settlements of the animal registered 17 species of rodents, five - predatory, one insectivore (eared hedgehog), two - birds, some reptiles and invertebrates. The closest relationship to the yellow ground squirrel burrows are animals, arrange them in their holes, - the average ground squirrel (Betpak Dala South Balkhash), small gopher (West Betpak Dala), clawed ground squirrel and a large gerbil (Muyunkum), red- gerbil (Or the left bank) and Tamarisk midday gerbil. Of the four-legged predators - polecat, of birds - Gavel-dancer and less - Little Read more [...]
Changes in population. Average gopher inherent fluctuations in the number of duration of a few tens of years, periods of depression, which in some parts of the range are manifested in different ways.
Our long-term steady-state studies, combined with a route studies have shown that in the Betpak Dala after 1950 there was a sharp increase in the number of ground squirrels, while in 1938 it was very low (Beloslyudov, 1948). Low number of this animal in the 30's, is one of the reasons for not including it in the "core fauna" mammals Betpak Dala.
Pointing to cause sharp Read more [...]
Within its vast area tailed ground squirrel eats various kinds of herbs - onion, grasses, butterfly, etc., eating their leaves, stems and buds of shrubs, berries and mushrooms. The role of animal food, apparently, is more significant than in other species of ground squirrels. In the diet is dominated by relatively concentrated feed - seeds and grains.
Long-tailed ground squirrel food in Jungar Alatau described Bekenova A. (1964, 1966). During the three years of steady work (1962-1964 rm.) They analyzed the stomach contents of 893, 105 pairs of cheek pouches, and about 430 will go. The basis Read more [...]

The Asian long-tailed ground squirrel is very close to the American parakeet gopher - Citellus parryi Rich., 1827. The latter are somewhat Read more [...]
Status. Rare species with suboptimal degradable, declining numbers and declining habitat are vulnerable to factors otnosheniiyu biogeotsenologicheskogo human or nature.
