Columbian Ground Squirrel / Spermophilus columbianus

This Columbian Ground Squirrel gave me some fun moments last year, especially when I tried to catch it with its mouth wide open, mid-squeal. By the time my camera had processed each shot, the mouth was closed again. However, I did get a few "screams", LOL. This was seen on the way home after a hike at Ptarmigan Cirque, off Highway 40, Kananaskis. We get a different kind in the city - Richardson's Ground Squirrel.
