There’s an elusive fox roaming the southern Sierra Nevada, and experts are trying to learn more about its behavior and breeding success by analyzing one of the few traces of its presence poop.
Living in areas above 9,000 feet in elevation, the fox is smaller than most, has fuzzy paws, and a thick fur coat–all adaptations to help it survive the heavy winter snows and challenging alpine conditions. Its fur can range in color from red to black to grayish-brown.
