Songbirds, akin to professional singers, benefit from daily vocal practice to enhance performance and attract mates. Conducted by Iris Adam and her colleagues at the University of Southern Denmark, the research is the first to establish that birds' vocal muscles require regular exercise for optimal functioning.
Interestingly, the study may help unravel the mystery of why birds engage in a dawn chorus. While some birds sing for social bonds or territory defense, the research suggests that the morning singing routine might be a form of vocal exercise, helping birds keep their voices in shape.
