Key points
- Bird songs from 367 species share acoustic patterns with human speech and song.
- These patterns are present in both vocal learning and non-vocal learning bird clades.
- Vocal learning ability did not systematically affect the similarity of bird songs to human vocalizations.
- The study analyzed over 74,500 bird vocal elements and 15,000 human speech/song elements.

Abstract
Bird songs are often described as analogs to human speech and songs, but expansive comparisons are necessary to determine analogy and mechanistic substrates. By analyzing global corpora consisting of 367 bird species (>74,500 vocal elements from ~5900 songs) within two clades of vocal learners (oscines and hummingbirds) and related nonlearners (suboscines and nightjars) and 52 human languages (>15,000 elements in >800 speech or song phrases), we revealed common patterns in bird songs that resemble prevalent patterns in human speech and song with variation in resemblance to speech or song. Vocal learning did not systematically affect acoustic patterning or similarity to human vocalizations. These data underscore the deep analogies between bird and human vocalizations and convergent motor mechanisms shaping communication.
