Last year my youngest and I assembled and painted a small wood birdhouse. I sprayed a clear coat of UV protection on it and left it in the garage to dry, for a year. The year was not intentional, life got busy, and whenever I would see it in the garage I was on a different mission. Then iNaturalist popped up a message that it is chickadee breeding season and showed a bird house the same size as the one we had in the garage. That was my sign.

I found a length of chain and a spring hook and attached the bird house about 7 feet above the ground at the back side of the yard. I can just barely see the small house from my kitchen table, so now we wait and see if any birds find it acceptable.
