syrinx

Type of Speech: 
Definition: 

the vocal organ of birds located at the base of a bird’s trachea, which produces sounds without the vocal cords of mammals. Sound is produced by vibrations caused by air flowing through the syrinx. 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.
