For the last five years I have been traveling around United States of America in a very large motor home. I have been to every single city in the United States over 10,000 population and I have been to all the state parks.

I have noticed something that is very interesting and an observation, which is worthy of further scientific research and something we should spend money on. Many birds make birdcalls and when they do this I have noticed that the motor home systems, which are under pressure, such as the water supply relieve that pressure and you can hear a sound in the pipes specifically after a birdcall. Certain birdcalls use sound energy and they do more than just make noise.

If we can replicate the birdcalls in a scientific situation in a lab and increase the power and intensity, we should be able to use the sound waves to increase and decrease pressures of gases, liquids and specifically water in the enclosed and encapsulated environments. It is amazing that Mother Nature can teach us so much about physics. Millions of years of evolution have obviously solved many problems.

The question is why do birds need to create pressure waves of liquid in the first place? Does it cause worms to come out of the ground? Does it cause little critters to increase blood pressure and make them move so the birds can see them to eat them? Does it help birds find water to drink?

Why do birds have the ability to affect things under pressure? Does creating such pressure increase the blood pressure of fellow birds to wake up the morning? Inquiring minds want to know and therefore we must do more research because I can't find anything on the Internet to help me solve this question or problem. Please consider this in 2006.
