Which of the following organs produce sound in birds?

Options :
  1. Trachea
  2. Bronchus
  3. Larynx
  4. Syrinx
Answer and Explanation :-

Answer: Option 4


Syrinx is the name for the vocal organ of birds. Located at the base of a bird's trachea, it produces sound without the vocal chords of mammals. The sound is produced by vibrations of some or all of the membrane tympaniformis (the walls of the Syrinx) and the pessulus caused by air flowing through the Syrinx. 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.
