Ingestive and vocal mechanisms in birds: A parallel?
Published online by Cambridge University Press: 01 August 1998
Abstract
Parrots prepare for vocalization by a ventro-caudal retraction of the larynx. This laryngeal movement, which “frames” vocal sequences, is similar to a movement used by pigeons as a preparation for suction drinking. The air-pressure events involved in such movements can trigger either suction drinking or vocalization. This suggests a possible evolutionary link between these ingestive and vocal mechanisms.
