The thirteen-lined ground squirrels have solitary habits, shown by agonistic behaviors to squirrels invading their own areas, which they've evolved, requiring less energy and the risk of getting injuired. Tail-flicking is also evolved from their solitary habits, which allows them not to violate other squirrel individuals' space. [5]
Ictidomys is a North American genus of rodent in the squirrel family, which contains the thirteen-lined ground squirrel, the Mexican ground squirrel, and the Rio Grande ground squirrel. These species were included in the species-rich ground squirrel genus Spermophilus until molecular data showed that this genus was not a natural, monophyletic ...
The thirteen-lined ground squirrel has an alternating series —approximately 13 in number — of narrow, solid, whitish lines adjacent to broader, darker brown bands containing distinct white ...
Whitaker examined the stomachs of 139 thirteen-lined ground squirrels and found bird flesh in four of the specimens and the remains of a short-tailed shrew in one; [41] Bradley, examining the stomachs of white-tailed antelope squirrels, found at least 10% of his 609 specimens' stomachs contained some type of vertebrate, mostly lizards and ...
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 ...

The Mexican ground squirrel is omnivorous, but eats primarily seeds and grains. [4] Its diet includes seeds, nuts, grains, roots, bulbs, plant stems, leaves, mice, insects, and eggs. [4] It often stores seeds, grains, and nuts in its cheeks pouches and takes them back to its den to eat later. In the summer it eats insects.
Spermophilus is a genus of ground squirrels in the squirrel family. [1] As traditionally defined the genus was very species-rich, ranging through Europe, Asia and North America, but this arrangement was found to be paraphyletic to the certainly distinct prairie dogs, marmots, and antelope squirrels.
