"What messages do animals send to each other using sound? How can we decipher them? What lessons might these messages offer for understanding the origins and workings of our own communication? Scientists who study bioacoustics try and answer these questions, using physiology, animal behavior, and evolutionary biology to understand how and why animals communicate via sound. In this book, Nicholas Mathevon offers readers an accessible overview of the field of bioacoustics, from the mechanisms of sound to its complex social function. Comprising short, accessible chapters, A Sound Journey explores how sound travels underwater, the act of hearing, and how animals use sounds inaudible to humans. Mathevon also shows how animals use sound to communicate in various circumstances, including parent-offspring relationships, conflict, expressions of emotion, and complex socialization. The study of acoustic communication enables a better understanding of the complexities of animal behavior, and the book uses examples from throughout the animal kingdom to illustrate how discoveries in bioacoustics have revealed various species' behaviors. In the final chapters, Mathevon explores animal "language" and the various philosophical and biological implications of this topic, both for various wild and domesticated species and for our understanding of how human communication systems developed"-- "Songs, barks, roars, hoots, squeals, and growls: exploring the mysteries of how animal communicate by soundWhat is the meaning of a bird's song, a baboon's bark, an owl's hoot, a dolphin's clicks? In The Voices of Nature, Nicolas Mathevon explores the mysteries of animal sound. Putting readers in the middle of animal soundscapes that range from the steamy heat of the Amazon jungle to the icy terrain of the Arctic, Mathevon reveals the amazing variety of animal vocalizations. He describes how animals use sound to express emotion, to choose a mate, to trick others, to mark their territory, to call for help, and much more. What may seem like random chirps, squawks, and cries are actually signals that, like our human words, allow animals to carry on conversations with others.Mathevon explains how the science of bioacoustics works to decipher the ways animals make and hear sounds, what information is encoded in these sound signals, and what this information is used for in daily life. Drawing on these findings as well as observations in the wild, Mathevon describes, among many other things, how animals communicate with their offspring, how they exchange information despite ambient noise, how sound travels underwater, how birds and mammals learn to vocalize, and even how animals express emotion though sound. Finally, Mathevon asks if these vocalization, complex and expressive as they are, amount to language.For readers who have wondered about the meaning behind a robin's song or the cicadas' relentless "tchik-tchik-tchik," this book offers a listening guide for the endlessly varied concert of nature"--
