@stevelee raised the subject of sharpness and BIF, and I remarked that a bit of wing blur could give the sense of motion but the beak and eye should be sharp. I recall now some shots I took 9 years ago, when I was very young and had a 300mm f/2.8 II + 2xTC on a 7D (unfortunately I was just taking jpegs then). Suddenly, along came my only chance of a hovering kingfisher, and I was set up at iso400 and the shutter speed was 1/330s - so small that it is upscaled 2x to post. I got the head perfectly in focus, and had almost the ultimate wing motion. It does show something. Today, I would have 20-30 shots at 1/3200s and make a gif.
