Ideas: Tuning in to nature

Sounds are everywhere. Animals, especially birds, create tailored calls to find mates, to alert others of predators, and to establish territories. Insects, such as crickets, cicadas and grasshoppers, are present in nearly all ecosystems, and typically keep the “rhythm” of a place through their pulsating sound production. Amphibians also contribute to the rhythm of nature; in some places, they do so in such large numbers that it becomes deafening.
