The flock appears to be the leader. Here's a great You Tube flick of a small flock of starlings defending themselves against an attack by a hawk. The behavior of the "flock" in making in what appears from our perspective to be making singular decisions becomes more apparent. https://www.youtube.com/watch?v=b8eZJnbDHIg Of course each of the individual starling are reacting collectively by bunching up closer together to stymie the Hawk, but that's the whole point. Visually speaking, it appears to be the resulting collective behavior that is most startling and apparent. The collective behavior is greater than the sum of its parts.
