A couple of years ago I bought and assembled a martin house. Concreted the main post in the ground, raised the birdhouse to its place in the sky. And I got house sparrows. I have lots of birdhouses for sparrows. So after two years, I took the martin house down and in its place strung lightweight aircraft cable from the four corners of the backyard, crossing in the middle on the top of the martin house pole.
For those of you who have built dragonfly perches before, what do you think? Is this mad genius? Was the aircraft cable (or the martin house for that matter) a waste of good money?
