Normally swifts zip past our tower at high speeds and zig-zag off into the blue, leaving me with a dozen images of nothing but sky. If you've ever tried to photograph a chimney swift, you know what I'm talking about.
But this chimney swift and his two traveling companions made to slow circles of our birding tower, probably checking it and our chimney out as possible nest sites. After their first slow circumnavigation, I realized what was going on and grabbed the camera. This was the only shot I got that had a sizable bird in the frame.
Here it is cropped slightly.
