The average length of an Arctic ground squirrel is approximately 39 cm (15 in). Since Arctic ground squirrels undergo drastic seasonal changes in body mass, it is difficult to give an average mass; [7] adult females are close to 750 g (26 oz), while males may weigh nearly 100 g (3.5 oz) heavier.

A team of scientists from Russia, Hungary and the United States recovered frozen Silene stenophylla seeds and remains from the Pleistocene in 2007, while investigating about 70 ancient ground squirrel (genera Urocitellus and Geomys ssp) hibernation burrows or caches, hidden in permanently frozen loess-ice deposits [1] [2] located at Duvanny Yar ...
Ground squirrels are rodents of the squirrel family that generally live on the ground or in burrows, rather than in trees like the tree squirrels.The term is most often used for the medium-sized ground squirrels, as the larger ones are more commonly known as marmots (genus Marmota) or prairie dogs, while the smaller and less bushy-tailed ground squirrels tend to be known as chipmunks (genus ...
Shorter burrows are dug as hiding places. This ground squirrel's home range is two to three acres (0.8 to 1.2 ha). Late in life, naturalist John James Audubon made a final expedition to the western plains in search of four-footed mammals. These striped ground squirrels would be tempting prey for many birds, especially hawks and owls.
[2] [3] Marmots are the heaviest members of the squirrel family. Total length varies typically from about 42 to 72 cm (17 to 28 in) and body mass averages about 2 kg ( 4 + 1 ⁄ 2 lb) in spring in the smaller species and 8 kg (18 lb) in autumn, at times exceeding 11 kg (24 lb), in the larger species.
The Columbian ground squirrel is one of the largest members of the genus, the largest being the Arctic ground squirrel. [2] They have a relatively sturdy, robust build. They measure 325–410 mm (12.8–16.1 in) in length overall, with a tail measuring 80–116 mm (3.1–4.6
The greatest predator of the ground squirrel is a snake—the type of snake varying by the locality. As a result, ground squirrels have evolved to perform anti-snake displays to defend themselves. [6] These squirrels tend to be put on a prominent display, specifically by moving their tail back-and-forth horizontally.
