A friend used to jog around the university I worked at; he'd jog past an area that, for a month out of the year, was under a hawk nest. He came by commenting that he'd been dive-bombed by a hawk that was obviously guarding it's nest he said it had bonked him on the head and yelled at him -- he decided not to go jogging that way for a while after. I was kinda impressed that the hawk had "bonk human on head" mode as well as "use lethal claws to kill things and eat them later" mode -- seemed like an interesting level of restraint to bonk but not cut the human. That the crow had a mental map of the building sufficiently detailed to know "human on 8th floor may be able to help Charles get out out of net in front of human's cliff cave if I yell at him" seems several orders of magnitude more complex...
