Acoustical Communication in Birds
Birds have the greatest sound producing capabilities of all vertebrates, allowing them to communicate over long distances, in dense vegetation, and at night. The scientific literature on bird vocalizations began more than 400 years ago with the observation by Italian naturalist Ulysses Aldrovandus that ducks and chickens called even after their heads were chopped off, and noting that the source of their vocalizations was apparently sited in the body and not the head. The source is in fact a unique organ, the syrinx, which allows some birds to sing two songs simultaneously, and others to sing with a vocal range that spans four octaves. In tonight’s Science Café, you’ll learn about these and other unique adaptations for acoustical communication in birds.
