Murmur

teaches How murmurations work: every starling tracks seven neighbors, fear travels through the flock as a wave, and the shapes you see at dusk are the flock reacting to a falcon.

A flock of starlings wheels over a marsh at dusk, and you are the falcon. Every bird watches its seven nearest neighbors, so a turn away from you ripples through the whole flock as a wave. Fly at the flock to make it bend away, dive through it to squeeze and split it, and herd the whole murmuration into the shape of the cloud above the roost. Hold the fit at the gold mark for a moment to clear the level, before the sun touches the horizon.
