By April Pulley Sayre

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. 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.
