13-lined ground squirrel

The 13-lined ground squirrel (Spermophilus tridecemlineatus) is a rodent native to North America. It is characterized by its grayish-brown fur marked with 13 longitudinal white lines, which can appear as broken spots. This species is known for its deep winter hibernation, during which its body temperature drops significantly, and its heart rate and respiration slow dramatically.12

Ground squirrels, in general, are active during the day and possess short legs, strong claws, small ears, and a short to moderately long tail. Their coloration varies widely, and some species exhibit stripes or spots. Most ground squirrels are omnivorous, with diets including plant matter, fruits, insects, and sometimes small vertebrates or carrion. The 13-lined ground squirrel is also sometimes called a leopard squirrel or striped ground squirrel.1324
