The Universal Language of Birds: Unpacking the Hidden Patterns of Song A new study published in Science has revealed that birdsong is governed by a surprisingly simple set of rules.
Researchers analyzed over 116,000 recordings from more than 3,160 bird species worldwide and identified eight basic sound patterns that underlie thousands of different songs.
The researchers used an innovative approach called the "modulation power spectrum" technique to identify recurring sound motifs in birdsong.
