Tom:
What an extraordinary collection of photos you have taken. You are indeed a photographer extraordinaire! And you must spend just a little bit of time in the field...
As for the 3-set series entitled Sharp-shinned Hawk--this is a tough ID call, but I do believe this is a Coop. To me, lack of a significant forehead, as well as a couple of other factors, lead me to this (non-expert) conclusion. And I readily admit that I could well be wrong about this.
Anyway, I have truly enjoyed your photos on this site.
Best, Mike Marsh, Portland
