Birds can make two different sounds at the same time. Just as a piano player’s two hands can be playing two different sounds at the same time, even so many bird songs are combinations of two sound melodies.

Birds can use their lung air sacs to produce wild and beautiful overtones which add to their calls.

Bird songs are usually very simple to make. Ornithologists–people who study birds–easily understand how bird songs are made.

We beat drums, blow whistles and talk into kazoos to make noises. Besides bird calls coming from their throats, birds also use their feathers, beaks, wings and feet to make sounds. These sounds are called sonations.

The red-capped manakin does a funny moonwalk.

Snapping sounds like ones the grouse makes are thought to be caused by miniature sonic booms like jets make only it’s done by parts of the feathers.
