I know a rehaber who hand raised a RT and hacked it out. The RT left and she didn't see it for two years. Then one day she walked out her back door and the hawk came off the roof and bound to the top of her head, digging all it's talons into her scalp. I don't think you can accurately theorize what an individual bird is likely to do any more than you can say all humans will act this way or that way.
