I have a bluebird box on my property that has an opening at the top front just under the roof line. It's not really a whole it's a narrow opening that runs the width of the box. There are bluebird's nesting in it right now and they are feeding the chicks. The house wrens and tree swallows choose other boxes.

Years ago some guy in Wisconsin designed a bluebird nest box with a hole in the top. This worked for the bluebirds and kept the House Sparrows away. He said he was inspired by bluebirds that nested in fence posts out his way. I can’t recall if that was the entrance hole or a “skylight “ hole. But he said that the rain didn’t bother the bluebirds.
