Richardson's ground squirrel (Urocitellus richardsonii), also known as the dakrat or flickertail, is a North American ground squirrel in the genus Urocitellus.Like a number of other ground squirrels, they are sometimes called prairie dogs or gophers, though the latter name belongs more strictly to the pocket gophers of family Geomyidae, and the former to members of the genus Cynomys.
The round-tailed ground squirrel (Xerospermophilus tereticaudus), ... (8.0 to 10.9 in) in length including the tail which is from 60 to 112 millimetres (2.4 to 4.4 in ...
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 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]
The Uinta ground squirrel is a moderately sized ground squirrel, measuring 28 to 30 cm (11 to 12 in) in total length.They weigh about 210 g (7.4 oz) when they emerge from hibernation, a figure that steadily increases until they are ready to hibernate again in the fall.
The tail is relatively bushy for a ground squirrel, and at a quick glance, the squirrel might be mistaken for a fox squirrel. [8] As is typical for ground squirrels, California ground squirrels live in burrows, which they excavate themselves. Some burrows are occupied communally, but each squirrel has its own entrance.
The little ground squirrel has a stout, low-slung body, short legs and a well-furred tail. [4] It has a brownish-grey back with ochre and yellowish mottling. The head is notably darker with more intense ochre tones and the tail is a light, grayish-ochre color with a pale tip.
Rheithrosciurus is noted for having the largest known tail to body size ratio of any mammal, [6] with the volume of its tail including the air included in the fluff being 130% of the volume of its body. (Compare 90% for the red squirrel.) It is unclear why the squirrel has such a large tail but scientists have suggested that it may have evolved ...
