The Landing

I have no idea why I can't positively ID this amazing hawk. It lives and hunts in our neighborhood so we see it quite often. It's a bit larger than a Red-shouldered hawk, it's markings and coloring doesn't quite fit either Red-tailed or Broad-winged hawks. I'm leaning toward a juvenile Cooper's Hawk. All of these hawks are found in our area. Check out the *extras... and please tell me what you think it is. 
Thanks, m
