Description This squirrel has tufted ears and white on the underside of a broad tail. New ear tufts are grown in October, and may be inconspicuous by summer. The back is gray, with a rusty band. Some animals in central Colorado are uniform brown. North of Grand Canyon, the subspecies S. a. kaibabensis has dark underparts and all-white tail, and was once considered a distinct species. Elsewhere the tail is only white on the underside and the belly is white. The back and belly color are usually separated by a black line. There is also a dark melanistic form.
