Woodpeckers are ruining our birdhouse!
I always thought that woodpeckers ate bugs. But as we discovered they are also quite fond of seeds as well. They are quite fond of sticking them into a small crevice and then pecking at them until they break. Happily for them our birdhouse is a source of both seeds and small crevices.
I think at minimum it will need another coat of paint soon.
At least the birds are fun to watch.
