Episode Transcript: 

This is BirdNote.

For most birds, wings are for flying. For penguins, they’re for swimming. But for Rock Pigeons, they’re also for clapping. Startle a flock of Rock Pigeons, and you’ll hear something like this: Rock Pigeon wing claps. 

When Rock Pigeons erupt into flight, some of them may slap their wings together . It’s called a “wing clap.”  

A male Rock Pigeon will do this when courting. He’ll posture and coo alongside a female ... 

… then fly sharply upward in an aerial display. The brisk series of claps is a shout-out of his courtship plans to the female watching from the rooftop.

Short-eared Owls have evolved wing-clapping, too. These medium-sized owls fly by day on long wings, rounded at the tip. And mostly they fly slowly, gracefully, like enormous moths. But when a male displays to a female or attempts to warn off an intruder, together below his body in a burst of two to six claps per second, producing a sound that sounds remarkably like…applause.
