SCALE-FREE. “The change in the behavioral state of one animal affects and is affected by that of all other animals in the group, no matter how large the group is. Scale-free correlations provide each animal with an effective perception range much larger than the direct interindividual interaction range, thus enhancing global response to perturbations. Because the size of the flock doesn’t matter, a huge flock is able to respond to a predator attack as effectively and fluidly as a small flock.”
