The syrinx enables some species of birds (such as parrots, crows, and mynas) to mimic human speech. Unlike the larynx in mammals, the syrinx is located where the trachea forks into the lungs. Thus, lateralization is possible, with muscles on the left and right branch modulating vibrations independently so that some songbirds can produce more ...
Wild Australian magpies, lyrebirds and bowerbirds that interact with humans but remain free can still mimic human speech. [6] Songbirds and parrots are the two groups of birds able to learn and mimic human speech. [5] [7] Both belong to the clade Psittacopasseres.
