Drinking on the wing

The most unique shot of any bird I've taken is this one. It is a common poorwill. In a photo workshop I conducted in the Arizona desert, my group and I set up our cameras on an artificial pond to attract bats. Before the bats arrived, this poorwill did an unexpected lightning-fast fly-by to drink on the wing and then it was gone. It was pitch black, and the bird had broken an electronic beam that triggered two flash units, one on either side of the pond. We pre-focused on the beam before dark. Our cameras were set to trigger an exposure repeatedly every 10 seconds. Fortunately, the poorwil flew toward our cameras instead of away from them. The picture is so sharp that upon enlargement, you can see the venation in the tissue inside the mouth. In the original image, I had zoomed in too tightly (because I was expecting the much smaller bats) and the left wing tip as well as its reflection were cropped. So, I used 'generative expand' to rebuilt the missing wing tips. My settings were 10 seconds, f/11, and 400 ISO, and I used a 70-200mm lens.
