This fellow patiently watched as my spouse refilled the bird feeders. He remained for well over an hour afterward. I'm thinking this is a Coopers Hawk?
CLOSED: Coopers Hawk?
Always a tricky one, but the legs and toes look slender to me, so I'd go for Sharp-shin.
Thanks to all. Had given up on getting any more info and haven't checked back until now. At least I finally know. I've got a thing about knowing what I'm observing, mostly because friends complain when I'm not specific about what I'm posting.
