For imitative parrots, wagging tongues may be key to vocalization
... Although birds and humans share the capability to make
very complex vocalizations, it was generally believed that most of birds vocal complexity originated from the vocal sound source, the syrinx. The role of vocal-tract articulators, so important in humans, was believed to be only subsidiary in birds, a...
