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.
Most sources agree that using tools such as a strong plastic or metal shovel, and maybe ice axe, is vital; digging by hand is for emergencies only. [2] Digging a snow cave can be physically demanding. In perfect conditions with good snow, digging a snow cave for two or three persons often takes three to four hours to complete.
The underside is pale with a sandy-coloured abdomen. The large dark eyes are placed high on the head and the small, rounded ears are hidden in the fur. The dental formula is 1/1, 0/0, 2/1, 3/3. The legs are powerful with sharp claws well adapted for digging. Males are slightly larger than females otherwise they look alike. [3] [4]

The ears are small, and the muzzle long, with a projecting, almost pointed, nose. The limbs are pale, with large feet and long, straight, claws. They can be distinguished from the otherwise similar Cape and mountain ground squirrels by the fact that female striped ground squirrels possess three pairs of teats, rather than just two. [4]
Eastern gray squirrels are crepuscular, [24] or more active during the early and late hours of the day, and tend to avoid the heat in the middle of a summer day. [40] They do not hibernate. [41] Eastern gray squirrels can breed twice a year, but younger and less experienced mothers normally have a single litter per year in the spring.
During periods when the snow has covered most of the sagebrush, pygmy rabbits tunnel beneath the snow to find food. Snow tunnels are approximately the same height and width as burrows. They are quite extensive and extend from one sagebrush to another. [22] [23] Above ground movement during the winter months is restricted to these tunnel systems ...
