Franklin's Ground Squirrel ("Spermophilus franklinii") is a species native to tallgrass American prairie, from Canada to the northcentral United States. The species hibernates from early fall to spring, and bears a litter of 6-8 pups at this time. The species is not choosy in its diet, eschewing the typical herbivorous diet of most squirrels when it can find insects, eggs, young birds, and fruits, seeds, and nuts when they are available.

Due to the destruction of prairie, the populations of Franklin's ground squirrel have dwindled, approaching levels of concern. However, the species is prolific, and locally abundant.


Franklin's Ground Squirrel was first described by Joseph Sabine in 1822, who named it in honor of the British Arctic explorer Sir John Franklin.cite journal| author = Andrea C. Ostroff and Elmer J.

DNA sequencing of the cytochrome b gene has shown "Spermophilus" to be paraphyletic; in particular, Franklin's Ground Squirrel is suggested to be sister to a clade containing not only the Mohave, Round-tailed, Spotted, and Perote Ground Squirrels, but the prairie dogs as well.
