As starlings gather in the evenings to roost, often they will participate in what is called a murmuration — a huge flock that shape-shifts in the sky as if it were one swirling liquid mass. Often the behavior is sparked by the presence of a predator like a hawk or peregrine falcon, and the flock's movement is based on evasive maneuvers. There is safety in numbers, so the individual starlings do not scatter, but rather are able to move as an intelligent cloud, feinting away from a diving raptor, thousands of birds changing direction almost simultaneously. The question that has had scientists stumped is how a bird, tens or hundreds of birds away from those nearest danger, sense the shift and move in unison?
