Starlings are preyed upon by hawks and falcons, and it is plausible to consider a murmuration as a continuous movement towards the safety of the centre. As a result, the centre never stabilises and the murmuration twists and turns in a perpetual escape motion. There are several problems in viewing murmurations purely in terms of a selfish herd. Indeed, producing spectacular displays over the famous Brighton pier in Southern England every evening is probably not the best way to avoid the attention of predators. Instead, it could be that the murmuration itself provides a way of monitoring predators as they approach. Work in the 1970s showed that starlings in larger groups responded to the presence of a model hawk faster, and recent work has shown that the formation of ‘waves’ in murmurations is linked to reduced predation success by peregrine falcons. Waves propagate away from an attack, and so fluctuations in the local structure are likely also to be efficient in confusing potential predators. Waves of turning away from attacking predators are a prime example of information transfer
