Wonderful picture!
But this is a hawk for sure but I am not sure which one. My first guess is a darker morph of a Red Tailed Hawk.
A Golden Eagle will have thick feathers all the way down their legs, less banding and dark brown body with golden neck. Juveniles have vivid white patches in the wings and a white tail with black band~

I actually thought it to be a Red Tailed Hawk as well, but a friend insisted it was a young golden eagle. I didn't think it looked right to be an eagle myself.
