Mine were facing south, too, so that is okay. We get rain and wind from the other three directions, so south seemed best, and they loved it. Is you area around the blueboxes lawn? They don't like trees, bushes, flowers, or anything nearby. My closest tree is a good 500 or more feet off. Of course, now the boxes are down and I am thoroughly frustrated. Shelly..got your PM, thank you! I think I will go to the local birdstore and see what I can find out. Will you please PM me the phone number of the person you mentioned with the PVC boxes? Thanks! The bluebirds are still here, waiting for boxes to go back up! Poor babies.
Dang house sparrows. I can't believe them. Weird thing, too, is next door tree swallows always nest in my neighbour's mail box and are successful! The house sparrows don't bother them in there. Maybe I should set up a bunch of mail boxes all over my yard!
