• A new study has confirmed the long-held belief that birdsongs evolve as a result of age, population dynamics and movement of the birds.
  • Researchers gathered thousands of hours of audio of great tits (Parus major) and used artificial intelligence to analyze songs in the data.
  • They found that birds that move around a lot tended to know the popular songs, while the ones that didn’t had pockets with unique songs.
  • While older birds were found to act as repositories of old songs, mixed-age bird communities were found to have more song diversity.
