A female Ruby-throated Hummingbird came to the nectar feeder today. I had set up my camera and was going to photograph her with her bill plunged into the feeder. Suddenly she flew up and backward, a maneuver that Hummingbirds can easily do. I followed her and took a shot, then she flew back down again. Only when I looked at the images on the computer did I see that the camera had caught her in the act.
A second later, she was back at the feeder.
