The purple martin is a swallow, the largest swallow common in these parts, and many folks put up martin houses to attract them. Martins are a're sleek little speedsters, and their aerial accomplishments are amazing. How a bird can go from a sleek power dive into almost an immediate hover is beyond me, but I've seen these birds do just that, countless times.
Yesterday, while I was on the family land, I was offered an unused martin house. We're moving a trailer and the martin house had to be moved, so I put in in my truck. When I got home yesterday afternoon, I stood it up in the corner of the yard.
Common wisdom is that a martin house should be installed in February because the migration occurs in March and the martins will find the house and move in. I didn't know if installing a martin house in early June would benefit the birds, but I installed it anyway because a bird house standing up takes a lot less yard space than one laying on its side. Imagine my surprise when I looked in the corner of the yard two hours later and watched purple martins swarming across the sky.
