The thirteen-lined ground squirrel (Ictidomys tridecemlineatus), also known as the striped gopher, leopard ground squirrel, and squinny (formerly known as the leopard-spermophile in the age of Audubon), is a species of hibernating ground squirrel that is widely distributed over grasslands and prairies of North America.
It is brownish, with 13 alternating brown and whitish longitudinal lines (sometimes partially broken into spots) on its back and sides, creating rows of whitish spots within dark lines. This species has usually been placed in the genus Spermophilus with about 40 other species. As this large genus is paraphyletic to prairie dogs, marmots, and antelope squirrels, Kristofer Helgen and colleagues have split it into eight genera, placing the thirteen-lined ground squirrel in Ictidomys with two other species.
The thirteen-lined ground squirrel is strictly diurnal and is especially active on warm days. A solitary or only somewhat colonial hibernator, it often occurs in aggregations in suitable habitats. In late summer, it puts on a heavy layer of fat and stores some food in its burrow. It enters its nest in October (some adults... Wikipedia →

GBIF citizen-science records
It is estimated from how often the Thirteen-lined Ground Squirrel is recorded against all the mammals logged in Riding Mountain National Park (9 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
