If a tree falls in the Amazon rainforest and no one is there to hear it fall, does it make a sound? For the woolly monkeys it does. Trees are a part of the woolly monkey superhighway along the cloud canopy of the rain forest. If you remove a tree, you remove a woolly monkey bridge. If you remove a woolly monkey bridge, you may have prevented the spread of certain types of trees elsewhere in the rainforest – trees that provide homes and food for many species of animals. How does that work, you ask? Until recently, it was a mystery. In this book, we join Ruthmery Pilco Huarcaya and other scientists in Peru as they devise ways to study the hard-to-see woolly monkeys living high up in the clouds, and share in their remarkable discoveries about the woolly monkey’s importance to the survival of trees, plants and other animals who live in the rainforest. Recommended for grades 3-5.
