This bird house was given to us by our neighbor. His father made it. It is for blue birds. So why is it that we find families of flying squirrels living here?

And this one usually has a wasp nest.

We do have other bird houses that birds nest in. Actually most of the birds choose places we never expect them to choose. Last year we had a nest in a dishpan on a shelf on the back porch. Another made a nest in the broken monkey on a shelf.
