Every spring our backyard comes alive with birds of all descriptions -- cardinals, bluebirds, robins, wrens, woodpeckers, etc. The feeders are very popular with the birds, and unfortunately, with some members of the local "occupy feeders" movement. These two entitled individuals thought they could just raid the feeders, eat the food and damage the infrastructure -- wrong -- not in my backyard.
The first raider made the mistake of visiting shortly after dusk, and he offered a top of the head shot at 25 yards. The Watts-tuned .22 cal HW80K was more than up to the task, and raider number 1 dropped off the feeder and kicked for 10 seconds.
Raider number 2 was a 3rd shift visitor, requiring a more detailed plan. I set up the Bunker Hill driveway alert system ($18 at the local Harbor Freight) aiming at the feeder, went back up to the bedroom, loaded a pellet into the Watts-tuned HW80K in .22, loaded a pellet into the Vortek-kitted R9 in .177, and turned in to await the alarm. At 1:30 AM the alarm sounded, and the second varmint made the shot difficult by moving around, but eventually he presented a side-of-head shot at 20 yards. This shot stunned him, and a follow-up to the back of the head put him into "break-dance" mode. I put a .177 into his chest for good measure.
