Question

Why does the bird begin to sing? What characteristic trait of the bird is reflected through his singin.​

Answer 1

Answer:

Vocal sounds are made by a special organ only birds possess: the syrinx. The syrinx is located at the very top of the birds' windpipe. The air that comes in through the windpipe causes thin membranes to vibrate and produce sound. ... Non-vocal sounds can be made by other parts of the bird such as the wings or the beak.
