This is not the answer you are looking for, but try different AF settings. What works for me on the exposure side is auto ISO and manual aperture and shutter speed, usually 1/1000 sec and F7.1, hand held. Practice panning, and try Group AF and highlight protected spot metering, and shoot raw.
Good advice. I try to stay away from 15+ focus points and settle in at 9 or single spot focus for herons etc. Experiment. Keep in mind your af is going to grab contrast, and that could be a wingtip or an eye. I usually start at 1250 and 8 auto iso.
