The dominant male forms his territory to get access to food, females, favorable areas for hibernation and to discourage males in the area from mating with his group of females. The habitat of this species is being degraded by human expansion and increased agriculture. [18] Sometimes these squirrels carry food back to their den in their cheeks. The largest of the North American ground squirrels, arctic ground squirrels are burrowing rodents that resemble prairie dogs, with small ears, a flat tail, and a white-spotted back. Since Arctic ground squirrels undergo drastic seasonal changes in body mass, it is difficult to give an average mass,[5] but for adult females it is close to 750 g (26 oz), however, males generally are around 100 g (3.5 oz) heavier than females. They are most active on warm, sunny days but remain in their burrows during heavy rains and intense heat. Arctic ground squirrels hibernate in sleeping chambers 5 to 8 feet underground from September to May, but may appear in the winter for short periods. Save Comp.

Breeding occurs in May. Arctic Ground Squirrel Facts. Habitat Arctic ground squirrels inhabit arctic and tundra habitats at northern latitudes and higher elevations, and boreal forest and alpine meadows at lower latitudes and elevations (Byrom et al. The arctic ground squirrel lives in alpine and arctic tundra in bushy meadows, riverbanks, lakeshores, and sandbanks. It has a short, stocky body, stubby limbs, strong claws, and a short bushy tail. These squirrels are very vocal and are referred to as "tsik-tsik" by the Alaskan Inupiat Eskimos, due to the sounds they make. It is the only ground squirrel species in its range. In the absence of ice nucleators, body fluids can remain liquid while in supercooled state. The ground-dwelling squirrels are most likely to make homes in a wide variety of habitats and it includes savanna, temperate forests, desert, prairie, rocky slopes, subalpine forests, alipine meadows, arctic tundra, and shrub. The best theory as to why the squirrel's blood doesn't freeze is that the animal is able to cleanse their bodies of Ice nucleators which are necessary for the development of ice crystals. Peripheral, colonic, and blood temperatures become subzero. Here we compared the body mass and condition of adult female arctic ground squirrels, Urocitellus parryii (Richardson, 1825) (an obligate hibernator) in source and sink habitats. By late summer the male Arctic ground squirrel begins to store food in its burrow so that in the spring[11] it will have edible food until the new vegetation has grown. They prefer areas with well-drained soil. Here’s how hibernating squirrels live for months without water. But this little creature survives some of the most challenging weather conditions that occur on the entire planet. They will also eat insects, and occasionally they will even feed on carrion (such as mice, snowshoe hares and caribou)[17] as well as juvenile Arctic ground squirrels. They also forage for dry grass and nuts to store for winter months. People in Alaska, particularly around the Aleutians, refer to them as "parka" squirrels, most likely because their pelt is good for the ruff on parkas and for clothing. They develop quickly and are weaned when 28-35 days old, reaching independence at 6-7 weeks.

The "tsik-tsik" calls are made in response to threats and vary as between different predators. Arctic Ground Squirrel. In their Siberian environment the ermine is prey to snowy owls, arctic foxes, lynx, gyrfalcons, hawks and other large mammals and birds of prey. The dominant male will usually be the father of the young, however, if he does not guard the female properly after mating, she may mate a second time with a different male. In fall, these red patches are replaced with silvery fur. When they meet, nose to nose contact is made or other body parts are pressed together. Gestation is for three to six weeks, the female giving birth to one litter per year of six to eight young. [7] Arctic ground squirrels make shallow burrows in areas where the permafrost does not prevent them from digging. Summer coats include red/yellow colourations along the cheeks and sides of the animal.

The arctic ground squirrel ranges across northern, eastern, and southwestern Alaska at elevations ranging from sea level to well above mountain tree lines. Similar Photos See All. The variation in demographic rates between ground squirrels living at high and low elevation may arise from phenotypic responses of squirrels to different habitat structure. In addition, these squirrels are predated throughout their range by many carnivores. Habitat The arctic ground squirrel lives in alpine and arctic tundra in bushy meadows, riverbanks, lakeshores, and sandbanks. “Arctic ground squirrels can lower their body temperature below freezing when they hibernate but somehow they do not turn into ice blocks,” Bell explains.
