Then I put my camera up to the eyepiece of my binoculars. That was an interesting experiment. It's not a crisp shot, but it brings the bird close enough for identification.
I did see a crow swoop down toward the hawk. Later I noticed the hawk was gone and there were a few crows perched in the tree. By that time the sun was warming things up, and I guess the hawk was soaring on a thermal and looking for prey.
