Mark installed a bird house hole guard or protector on his sister's bluebird house since she was having trouble with squirrels chewing out the hole and making it larger. He hid a large washer around the hole and then shaped a wooden doughnut to cover the washer up.
Mark didn't say how the doughnut was mounted, but I assume it was glued around the outside. The washer would make it difficult to attach with screws from the back side.
Below are bird house hole protectors you can install easily on your bird house if you don't want something as fancy as Mark's:
No doubt the washer will slow a squirrel down. They may try to gnaw around the hole and could cause a lot of damage to the doughnut, but they will not gnaw through the washer. If given enough time, they could eventually dislodge the washer, but let's hope those squirrels give up and move on to natural holes before that happens.
Mark explained, "I know that there are many easier ways to install metal at the entrance of the birdhouse. But this way gives me the finished look that I wanted. Heck you could just take a can lid and nail it to the front after cutting a correctly sized hole in the center and it would work just as well. I just don't care for the look it would have."
