The Mighty Jungle (Paperback)
Jungles are home to many unusual plants and animals. Many of their inhabitants produce a very loud noise for communication. The noise can be so loud that it's difficult to hear anything else. People who live near jungles have learned to coexist with the constant noise. However, learning about the source of the noise can help you figure out how best to cope with it.
Animals use the sounds made in jungles to express themselves and find food. Most common are insects such as crickets and cicadas. They produce their signature sounds by rubbing their legs against their wings or body. In this way, insects make their unique noises to signal their presence and attract mates. Smaller animals also make noise to communicate; bats use echolocation to find their way around. They echolocate by producing a high-pitched screech and listening for the sound's echo. This gives them information about the world around them and lets them navigate during the night.
Jungle noises also keep dangerous animals at bay; they provide an early warning system for approaching threats. Some animals make noise as part of their defense mechanisms; crickets have a natural defense mechanism in their hind legs, which they use for self-defense if threatened. Insects also use noise to communicate danger; cicadas produce a different call when a predator is near. This way, other insects know to run away from danger without having to fight first.
The jungle is one of the most difficult natural environments for humans to live in. The constant noise can be very annoying and even produce physical effects on people's health. However, people have learned to deal with this annoyance by understanding how it works. By listening for patterns in animal noises, you can tell what's happening without exposing yourself to danger or excessive noise levels. In this way, understanding the noisy environment you live in can help you manage it better.
