I was about 30 feet away from a red tailed hawk eating a blackbird he just killed on my driveway. About 10 other black birds were dive bombing him while he slowly ate. the black birds gave up when they could see he was about done. I have never been that close to a hawk before, and for like 10 minutes, although he may have been there for another 10 minutes, for all I know. He did notice me. All that was left was feathers.
