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 Mohave ground squirrel measures about nine inches from nose to tail and feeds on leaves and seeds from February to July. Near the end of July, the squirrels begin a period of estivation, but this may occur as early as April in drought years. Populations generally do not reproduce following winters with less than 80mm of precipitation.
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.

Thirteen-lined ground squirrels can survive in hibernation for over six months without food or water and special physiological adaptations allow them to do so. [6] During torpor, these squirrels maintain hydration by redistributing and storing osmolytes like sodium, glucose, and blood urea nitrogen in different body compartments (to be ...
