No kidding! Wonder if it's the same one.
The only other hawk it could be is Sharp Shinned. They look a lot alike, but a Sharp Shinned won't sit out exposed like that. They hide in trees and brush and are very hard to see. I had one eating wild quail in the yard last month. I knew something was there, could hear it thrashing in a big oak. Before I even saw it, it took off, flapping like crazy, and a poor dead quail plopped down behind me. The hawk came back and finished eating it later. Waste not want not!

I was just trying to be funny.
I view hawks with such mixed emotions - they're beautiful and good at what they do, but it's such a downer when they kill a chicken or duck. They've forced my chickens into a run and the ducks only range because they hang out with the gaggle of geese. 
Besides the size, also notice that its nape is the same shade of gray as the cap unlike the adult Cooper's in your last photo which has a lighter gray nape. You sure get some great views of these guys!
