Well, from my understanding a flock is formed based on individuals' tendency to be closer to each other in order to decrease the chance of getting eaten by a predator! and the closer you are to the center of the flock, the slimmer the chance. so there is a never ending competition to get to the middle of the flock, which is one reason for the dynamic behavior of the flock. It's sort of similar to the way cyclists compete for the 2nd position for the most part of a competition, since air resistance is much lower compared to the foremost position. So you can see the first guy slowing down and moving back to the nearest hole in the group every once in a while. Similar to the cyclists, some birds are stronger and end up being in those good spots most of the time. I remember the narrator saying something about males pushing others to the edges. Not sure if we can see that as a social position, as we know it.
