Keith, I also live in an HOA subdivision with a very small yard, so feel very fortunate to have the bluebirds nesting on my property. I put up a true bluebird house in the front yard this year, which is the one that bluebirds are going for brood # 2. I know our HOA, though, & am waiting for the day that they tell me to take the birdhouse down. I will appeal that one until I win! Hope it all works out for you & that male.
