The young hawk in question is an immature Cooper's hawk. That was a toughie, since the bird was being held and its body was crumpled in an awkward fashion. The flat head should have been a big clue.

I don't know what the final prognosis was for the bird, it did look good, there were no broken bones. This time of year a lot of young Coops learning to hunt fly into windows when pursuing birds at feeding stations.
