One of my neighbors has had a screech owl box up for years, with the occasional little face peeking out. We put one up about ten years ago, but never saw any activity, and when the branch it was on was rotten, the box sat around for a few years. But when we saw that cute face, we decided to rehang our box, which was designed with room for a security camera to fit right in. We thought it might be too late in the season, but we went through some serious shenanigans anyway, figuring out how to hang this large box high enough that I can see it from my office window.
