In the fall and spring, thousands of people come to the marshlands of the Wadden Sea, between Denmark and Germany, to watch huge flocks of starlings take flight at sunset. The birds synchronize their movements in a flocking behavior called murmuration. They swoop, shift, and turn as one, creating incredible shapes in the sky.
Birds of a feather flocking together
