2nd attempt to post with photo---wish me luck!

I was driving down a rural road in VA last week and saw a house with 40 or more birdhouses. It was less than ideal---only some had baffles and many of those were homemade and of questionable effectiveness. BUT there were purple martins and TRES by the DOZENS swooping in & out. I pulled over and stared with my jaw dropped for a while, wishing I had my binoculars. Made me want to move ASAP...
