A couple of years back, a red tailed hawk landed in my back yard (about 20 feet from my back door) with a squirrel that it had just killed. It sat there for about a half hour and ate...then took off with what was left - for his nest I'm presuming. It was fascinating in that I went out and sat on my back and watched, and it could care less. I have a few pics laying around somewhere of 'the feast' - will see if I can dig them up..
