lol....Those guys do have a certain greed.....tell you though...If you get a hunk of orange peel and chuck it into a crowd of gulls one will grab it...fly a couple yards...drop it and another will grab it and repeat.....til evey idiot bird in the group has had it at least once....sometime the whole process will start again.
It wont hurt them, because they won't eat it.....it tastes bad....but their own greed causes them to play keep-away sometimes for hours depending on flock size. I guess if enough ffolks did that they beggars would quit the thievery attempts. But it is funny to watch. Reminds me of a rugby match
