The syrinx (from the Greek word "σύριγξ" for pan pipes) is the vocal organ of birds. Located at the base of a bird's trachea , it produces sounds without the vocal folds of mammals. [ 1 ] The sound is produced by vibrations of some or all of the membrana tympaniformis (the walls of the syrinx) and the pessulus , caused by air flowing ...
Birds regulate the airflow through the syrinx with muscles—M. syringealis dorsalis and M. tracheobronchialis dorsalis—that control the medial and lateral labia in the syrinx, whose action may close off airflow. [2] Song may, hence, be produced unilaterally through one side of the syrinx when the labia are closed in the opposite side.
Vocal Bird anatomy: Birds produce sounds through the air that passes through the Syrinx, which is shown close up in the bottom right. In order for birds to produce sound, they use an organ located above the lungs called the syrinx , which is composed of tracheal rings, syringeal muscles, Tympaniform membrane, and internal bony structures that ...
The syrinx and sometimes a surrounding air sac resonate to sound waves that are made by membranes past which the bird forces air. The bird controls the pitch by changing the tension on the membranes and controls both pitch and volume by changing the force of exhalation.

Lacking a syrinx—the vocal organ of birds—its only vocalizations are grunts or low hisses. It nests in caves, hollow trees, or thickets. It nests in caves, hollow trees, or thickets. Each year it generally raises two chicks, which it feeds by regurgitation .
