Siberian chipmunks usually live solitary lives, but during the winter they create a burrow, which they often share with another chipmunk. This method illustrates one way in which this species communicates with one another. The Siberian chipmunk marks its territory with urine and oral glands inside of its cheeks. The territory ranges from 700 to 4000 m and is larger for females than males and is also larger in autumn than spring. The Siberian chipmunk lives in loose colonies, where every individual has its own territory. Also they have trouble overcoming man-made and naturally occurring obstacles, like roads or swamps. However, this species has a low ability of dispersal, and since they are mainly introduced into woody forests or urban areas with greenery, they have less potential to be naturally dispersed to other regions. Tamias sibiricus is able to survive in various environmental conditions, anywhere from 29°N to 69°N and -65 ☌ to 30 ☌. In Europe, the introduced populations usually live in deciduous forests, mixed deciduous and coniferous forests, or urban areas with greenery. They are usually found in coniferous forests, stony areas within forests and mountains, habitats filled with shrub, along waterways or roads, or other small patches of agricultural land. The Siberian chipmunk can survive in a variety of habitats and conditions. While thousands of animals were introduced to new environments, their naturally slow spreading, 200 to 250 meters per year, prevented them from rapidly moving to areas beyond Europe. Other Siberian chipmunks escaped from captivity and inhabited the forested areas of Europe. Owners released these animals because they no longer wanted them as pets, or the owners purposefully freed the chipmunks to live naturally in the wild. By the 1970s, the Siberian chipmunk inhabited suburban forests and urban parks in Belgium, France, Switzerland, Germany, Italy, the Netherlands, and Austria. Human introduction is a major risk for the spread of this species into other forests and areas. Between 19, South Korea exported more than 200,000 individuals to Europe. During the 1960s, South Korea began to export these animals to Europe as a part of the pet trade. Siberian chipmunks were found only in their native range of Eastern Asia until the 1960s, when this species was introduced to European countries. However, when placed in captivity, as seen in Europe in the 1960s, they have the potential to live anywhere from 6 to 10 years. Their small size may contribute to their relatively short lives, which tend to range from 2 to 5 years in the wild. The Siberian chipmunks are not known to exhibit sexual dimorphism, and size and body proportions are the only way to distinguish younger chipmunks from older ones. Even though the Siberian chipmunk normally grows to 50–150 grams, this species is relatively small compared to other Sciuridae, such as the Red Squirrel. The weight of adults depends on the time of year and food availability. It is 18–25 cm long, a third of which is the tail. Typically the Siberian chipmunk has 4 white stripes and 5 dark stripes along the back. It is the only chipmunk found outside North America, and this animal is classed either as the only living member of the genus Eutamias, or as a member of a genus including all chipmunks.Īlthough these animals can exhibit slight variations in coloration in different geographic regions, they possess several common characteristics. The Siberian chipmunk was imported from South Korea and introduced in Europe as a pet in the 1960s. The Siberian chipmunk or common chipmunk (Eutamias sibiricus) appears across northern Asia from central Russia to China, Korea, and Hokkaidō in northern Japan.
