During migration, common starlings may fly at speeds of 60-80 km per hour. Within this densely packed group of birds, the distance between them is sometimes only a bit more than their body length.Despite this tight spacing,they make astonishingly deft turns all together that appear to be conducted entirely in unison.When birds congregate in such big crowds, their collective intelligence makes it easier to discover food, stay on track along migration routes and avoid danger as many eyes and ears are more efficient in assessing potential hazards than an individual could do alone.
