Sandra Markle is a whiz with an animal story and this book is no exception. Upon learning about a project in Peru where camera traps were being set high up in rainforest trees, she had to know more. Her curiosity led to a scientist who was using the camera traps to study a seldom-seen, but necessary rainforest creature, the woolly monkey. Considered the rain forest’s gardeners, these animals are central to the spreading of seeds throughout the rainforest. Markle loves to find out why scientists study animals and how these animals fit into the ecosphere they inhabit and she conveys that intellectual curiosity and passion through her storytelling. This book explains the function of camera traps and delves into the information gathered about the woolly monkey from these devices. Readers will learn about the ecosystem of a rain forest and will hopefully be inspired to continue to learn more about keystone species and the need to fight for and protect the natural resources on Earth before it is too late. Plenty of beautiful photographs accompany Markle’s clearly written text and a few QR codes are included in the book so readers can further explore this topic and see/hear the woolly monkeys in their natural habitat. A glossary, index, and list of sources for further reading are all included. This book would be appropriate for school libraries with students in grades 3-6 but could also be put in public libraries and given to readers interested in the scientific process and/or fascinating animal stories.
