"I saw a few of these ""tassel-eared squirrels"" in the higher Ponderosa Pine areas on Mt. Lemmon in AZ. Apparently this is an introduced population. Unfortunately, the only opportunity I had to get an image was this one running away down the road. A careful examination will reveal a bit of the rusty red patch on the back and the tip of one of the tassel ears showing beyond the white-edged tail."
