We heard the call, and saw him scurrying through the rock field. The attached files were shot with a 55mm lens. (One pic, zoomed in the second file.) It hid before we could get the big lens on for a closeup. He was the fattest pika I've ever seen.
Multiple individuals heard and seen on this scree slope right along the Pinnacle Peak trail. The individual in the photo crossed the trail several times
Saw three pikas in the same general location. One was harvesting, one was making the "wind-up" noise, where they do the short calls in succession, before the single longer regular call.
