We have a critter called a pocket gopher out here. He spends about 99% of his time underground, burrowing along, eating the roots of every plant he comes in contact with. He only comes to the surface to clean out his tunnel and give himself room to work. He makes a hole to the surface and then pushes the accumulated loose dirt out of the hole. It makes a little earthwork around the hole and only rare occasions that you actually see him is when he is doing this excavation project. It's really the only window of opportunity for potting the destructive little bastid. (They make an awful mess wherever they go.)
But it's very much sniper work a la the trenches of WWI. His head will appear only briefly, and then only partially. You will have only a half-second or a second to get off a shot at a target barely an inch square. Only by guessing where he will appear behind his earthwork will give you any chance at all of making a hit on one of them. Plus the fact that their appearances are so infrequent and so unpredictable that you could stake out a spot for a whole day and never see one. This is an exercise in futility in which I do not indulge.
They have been very active lately as the season changes, and my office window looks out on a swath of my laughingly called "yard" where they have been at work. When I see one throwing dirt around his parapet I will go out with my Ruger M77/22 and see what work there is to be done. I've got one of those ranging BSA Sweet 22 scopes on mine and it does a good job of accounting for elevation at different ranges. Shots are normally between 30 and 75 yards.
Success rate? Very low. They are wary, and you usually only get one shot before they go to ground for a long, long time. But it does give me a break from desk work. So far there has been no return fire, although I could swear that the one yesterday was wearing a little helmet.
The photograph is not mine. I found it on the 'net, where it had no attribution. My little friends don't trust me enough to let me make portraits. Very smart of them, too.
