— What sets it apart

In his courtship display the male climbs to 30 metres and drops in a dive. At the bottom he spreads his tail: the air sets the tail feathers vibrating and produces a sharp chirp. It is an instrumental sound, not a vocal one — the bird plays itself. In that dive he covers 385 body lengths a second: relative to size, the highest speed measured in any vertebrate, greater than a fighter jet’s.
