Summary:
Examines the work of several bioacousticians, scientists who study the sounds made by living creatures, discussing the results and importance of their research.
Excerpt/First Sentence(s):
Squeaks. Wails. Whistles. Snorts. Songs. Drumming. All over the globe, animals are making sounds, and these days, more than ever, scientists are listening to them. In a desert in Uzbekistan, Dr. Jan Randall records sounds that wild gerbils make when they thump their feet on the ground. At a waterhole in Africa, Dr. Bill Barklow listens to the recently discovered underwater sound of hippos. In Texas, Bill Evans rigs up microphones to record and identify the mysteries calls of night-migrating birds.
Publisher Description:
Can whales communicate across miles of vast ocean? Can elephants talk to one another with sounds we can not hear? Can birds' calls help us count them in the sky? These are the kinds of questions that drive the work of acoustic biologists. In Secrets of Sound, author April Pulley Sayre introduces us to three creative scientists - Christopher W. Clark, Katy Payne, and Bill Evans - who have dedicated themselves to researching how and why animals communicate. Sayre explores how new technologies and secret military information recently released are helping these scientists make exciting discoveries. Such work raises as many questions as it answers, and for the scientists (and readers) that's half the fun. This book celebrates the challenges of lab and fieldwork and the thrill of discovery. It not only explores the world of animal communication but also highlights the critical role scientific research can play in preserving endangered animals.
