Study reveals universal vocal patterns shared by birds and humans

A study published in the journal Science indicates that bird songs and human speech share nearly identical vocal patterns. Researchers found similarities in vocal coordination and variations adapted to social contexts, suggesting potential common biological mechanisms rather than just learned sound imitation.

Affiliated with institutions in Canada, the United States, and the United Kingdom, the research team analyzed a library of over 74,500 vocal elements from 367 bird species. The data, sourced from the citizen science website XenoCanto, included songbirds, hummingbirds, suboscines, and nightjars. The study compared these avian vocalizations against human speech and song across 52 different languages.

The analysis identified universal vocal patterns present in hundreds of bird species that also appear in human cultures worldwide. These shared patterns include small pitch intervals, regular and predictable rhythms, and the tendency to prolong the final syllable of a phrase.
