The lack of sharpness in the heron is probably some combination of shutter speed, possibly a little off in focus, camera shake, etc, etc. Shooting any bird in flight, even a relatively slow one such as this, is often a practice of futility for me, even back when I was using what many would term a "proper camera"....a DSLR, for that type photography.
I rarely try birds in flight these days. There are already enough things going on my life that are a source of frustration on a daily basis without adding something from the one thing I do for "fun".
