Another beauty, Alan. Beautiful bird, nice perch, great pose and detail. Top and back of head seem just a bit soft - I would have thought f/9 would have been enough dof.
Hi Alan, it's interesting that 1/500 of a second was enough to freeze him. Bill Dix noted that the back of the head is soft. Might you have tried a narrow aperture and a higher ISO? In that case, you'd have probably been able to stay at your 1/500 sec. with more DOF. ISO 200 seems unusually low for a small, fast-moving bird, even in good light. If what I'm saying here sounds like a critique, then fine, but really I'm asking; I just don't know.
