Least weasels are the smallest carnivore in North America, small enough to follow a mouse straight down its own burrow, and Indiana’s records concentrate in the forested hill country of Hoosier National Forest, Brown County State Park, and Clifty Falls State Park, a very different region from the prairie remnants that anchor most of the state’s other rare mammals in this rank range.
Records scatter across the colder months, January through February and again in November, with a near-total gap from July through October. That pattern likely tracks when snow makes tracks and white winter fur easier to spot rather than any real summer disappearance, since this species hunts year-round. NatureServe ranks it S2, imperiled, in Indiana.
