Bird Of Prey ~ jim Morrison

This is a composition made by me, the video shows an invasion of starlings swarms over some fields in Otmoor (United Kingdom). The effect that you see tumbling and banking in nervous unison and without colliding is caused by the interaction of each bird and the 7 birds around him. Current computer models assume that each bird interacts with all birds within a certain distance. But the new observations, however, show that each bird keeps under control a fixed number of neighbours - seven other starlings - irrespective of their distance, which is the secret of how they stick together.
Flocks remain incredibly cohesive - never leaving a bird isolated - when under attack by a bird of prey...
