California Ground Squirrel

Otospermophilus beecheyi

California Ground Squirrels are common along the ravines of the Paul Willis trail.  The most dense colonies are likely the ones under the bridges by Van Kampen and the Physical Plant entrance, and in the ravine below the Duck Pond.  The distinctive white line around their eyes, peppery brown coloration, and tendency to flee for holes in the ground rather than trees make them easy to differentiate from the eastern fox squirrels and western gray squirrels on campus.
