Vandalism

I have two bird feeders on this tree just outside the back door. The squirrels have left them alone for a few weeks but the one with the peanuts got vandalised yesterday. Today about 12 I put it back together and filled it with peanuts. When I came home at 3.30 the bottom had been dismantled and the peanuts were gone. So the score is something like Squirrels 699 - Berny 0. They're such clever wee things aren't they. This time they're undoing a wire clip on each side which holds the bottom onto the feeder. I have spent a lot of time trying to beat them but I never have.
