Cooper's Hawk - I think?

I was at work today inspecting an electrical transmission line and saw a hundred or more pidgeons sitting shoulder to shoulder on a wire. I thought I would take the same old shot of a bunch of birds on a wire and reached into the back seat to get my camera equipment. I turned around just in time to see one of the pidgeons fall like a rock to the ground and all the other pidgeons disappear. Then this hawk landed on the downed pidgeon and began to finish off it prey. The closest ID I could find is a Cooper's Hawk but I would appreciate help with the identification.

Yes Sparky, sure looks like it to me. Graeme

Nice captures joe, I'd add some contrast to the photos to make the hawk stand out a bit, esp on that last one which looks pretty sharp.. Well done.
