Welcome, Connie. I doubt that anyone has a nesting pair around you right now but they are shopping for boxes. Glad to have you here. The numbers of this group fluctuate from year to year. Right now it’s kind of small. How close are your 2 boxes? Bluebirds are territorial and normally like to be 300 feet apart from each other. Sometimes they don’t follow that rule but that’s the norm. It does help if they are not in view of each other. Example, one box in the backyard and one box in the front yard. But you can get other species in your second box like tree swallows, and chickadees
