Richardson's Ground Squirrels, AKA Gophers

I just went back to Alberta for a family reunion and had a chance to photograph some Richardson's Ground Squirrels. "Gophers" we called them, when I was a murderous kid with a .22 rifle on a farm in Saskatchewan in the 1950's. I thought shooting gophers was fine sport until I discovered that all I had to do was sit very still with the muzzle of my gun at the entrance of the hole the animal had gone down, and pull the trigger when it stuck its head up again. I killed one gopher that way and afterwards I left them alone.
