* 2 Tympanum * 3 first group of syringeal rings * 4 Pessulus * 5 Membrana tympaniformis lateralis * 6 Membrana tympaniformis medialis * 7 second group of syringeal rings * 8 main bronchus * 9 bronchial cartilage] Syrinx (Greek for pan pipes) is the name for the vocal organ of birds. Located at the base of a bird's trachea, it produces sounds without the vocal cords of mammals.cite book| last =Terres| first =J.

This sets up a self-oscillating system which modulates the airflow creating the sound. The muscles modulate the sound shape by changing the tension of the membranes and the bronchial openings. [ [ Direct observation of syringeal muscle function in songbirds and a parrot] Ole Næsbye Larsen and Franz Goller, The Journal of Experimental Biology 205, 25-35 (2002)] The syrinx enables some species of birds (such as parrots, parakeets, and mynas) to mimic human speech. Unlike the larynx of mammals, the syrinx is located where the trachea forks into the lungs, and because of this some songbirds can produce more than one sound at a time.
