It is, just as long as you are carefull about it for it is not fun to earn their ire either. If they dislike you enough they can start to fight back and teach others to follow their lead... and crows can hold a grudge for years. As to how you do it... taking them by surprise is best, you can't let them see you creeping up on them.
