I watched a Kestrel hunting across the expressway at the airport the other day. From my office, I could see that it was a beautiful male and quite possibly the same one I have been seeing all summer, though we do get some migrating through here this time of year, so can't say for sure.
I can definitely say he was fun to watch, though. Kestrels are such amazing acrobats. This one darted across a runway, then flew up straight and began to do its characteristic hovering. It then folded its wings, dove and bottomed out in a long glide just inches above the ground. It then moved on down the runway and repeated the whole process.
All in all, a beautiful sight. Of course, the fact that I saw the whole thing through a Leica 7x42 Trinovid I was examining for a customer didn't hurt, either.
