Birdsong carries meaning across open space, helping birds attract mates, defend territory and communicate with rivals. While there has been much research into the use of birdsong across species, researchers have lacked a single global framework that explains birdsong complexity and how it differs from place to place. But now, in a study recently published in Science, a group of researchers in France have analyzed more than 116,000 bird songs from 3,160 passerine species around the world, allowing them to identify eight common motifs and explain differences in birdsong.
