Admire your persistence. Suggestion: on my D80 I'd set ISO to 800 (I think your D90 could handle 1200ish) and shoot f7.1 or f8 at 1/640 with of course the VR on. I suspect the additional DOF would make the heron "sharper". Looking at the heron's beak, seems you have used a tad much post sharpening.
I often wonder why the forum does not support "larger" image files. I suspect this looks pretty nice in its original size.
