Can't believe there are no comments. Very well done. You are a natural. I'd vote against using sawdust in woodpecker boxes. Aspen wood shavings is what you want. They are soft and not splintery like cedar.
New to MO- put up bird feeders this winter and attracted lots of birds but woodpeckers started drilling our roof at 6AM every day. I had to take feeders down to get rid of the woodpeckers. Is there a way to feed birds and discourage woodpeckers?
