Birds Making their Songs

In Greek mythology, Syrinx the nymph was escaping Pan and ran to the edge of the river. She asked the river nymphs to help her escape, and they changed her into water reeds. When Pan blew across them, they made a melodic sound so he cut them and made a panpipe (pan flute). Interestingly, the apparatus in birds that makes their song is called a syrinx.

People have wondered about bird songs and how they can make more than one sound at the same time. Evolutionary ideas failed, since the answer supports special creation.

Researchers wanted to know how things work when birds to their songs — especially how they can do more than one sound at the same time. Evolutionary explanations failed, and there is no sign of a syrinx in dinosaurs or other critters. That's not difficult to understand if you drop the universal common ancestor evolution idea and admit that they are the product of special creation by the Master Engineer.
What makes the unique sounds of birds is a structure called the syrinx, found at a point where the trachea, or windpipe, splits into the bronchi, the passageways to the lungs. The syrinx is typically designed with a resonating chamber and elastic vibrating connective tissues called tympaniform membranes. Sound is produced when the membranes are pushed inward via muscular contraction and partially block the bronchi.
