"I loved this book! It's exciting and interesting and draws the reader in with dramatic anecdotes and humor about the study of all sorts of wildlife in their natural habitats...."
- Appraisal: Science Books for Young People

"This lively and informative book will be an excellent resource for budding naturalists."
- * Starred review, School Library Journal

"Field science...the tedium, the mess, the danger, the excitement, and the simple enjoyment of exercising one's ingenuity...is presented here, along with all of the issues scientists must weigh in their work."
- Booklist

"Such interesting and often amusing anecdotes, along with Sayre's expert knowledge of animals studies, reveal the unique challenges facing field researchers. Just exactly how do scientists determine the length of a coiled anaconda? How do they make an accurate count of the thousands of caribou wandering the tundra? Sayre's exhaustive yet witty text...discusses how scientists often rely on sheer tenacity and improvisation to gather and interpret data about animals....The author's enthusiasm will undoubtedly spark the interest of a new generation of Dian Fosseys and Jane Goodalls."
