Only thing to add is that when this happened outside my office building, the hawk flew to the top of a telephone pole in the center of the parking lot. Word spread around work and virtually everyone in the building (close to 200 people) watched it for quite a while.
I also saw a black vulture ripping something up in the lawn across the street from me. The vulture was huge and was quite unconcerned that it might be interrupted by any other animal!
