The Great Squirrel Robbery: Part 4

I have been struggling all week with how to keep squirrels from breaking into my "squirrel proof" bird feeder and eating all the food. I tried strong packing tape to keep the top on, and then I tried locking the top down with bungee cords. The squirrels quickly and easily broke through both. OK, let me think about this. Squirrels have sharp teeth and they were easily able to bite through the packing tape and the bungee cords. But squirrels can’t bite through steel and they can’t bite through the bars of thefeeding cage. What do I have that is steel and that is easy toput on and take off? Of course, I thought. Paper Clips!Big ones! Don’t try to hold the top down, just use the clips to prevent the squirrels from picking up the top. I put clips on both sides of the top and sure enough, they prevent the squirrels from being able to lift up the top. At least it’s worked so far. The squirrelshaven’t gone in to get the seed from the feeder. But I’m not entirely convincedyet. There maybe a squirrel Einstein that’s working to solve the problem of moving paper clips, and it won’t entirely surprise me to find out that the clips are gone one day soon! Thank you for your ideas, helping me to try to solve the Great Squirrel Robbery!
