Information can explain the dynamics of group order in animal collective behaviour by MacGregor, Hannah E. A., Herbert-Read, James E., Ioannou, Christos C.

“…Animal groups vary in their collective order (or state), forming disordered swarms to highly polarized groups. One explanation for this variation is that…”
