From rainforests to deserts, mountains to plains, the sea to the sky, animals raise their voices in an eclectic and thrilling chorus. This collection celebrates the unique calls of the keel-billed toucan, Guatemalan coatimundi, hammerhead bat, Central African elephant, urban katydid, and many more intriguing creatures whose sounds we seldom hear.

The NPR Sound Treks series features outstanding audio documentaries, stories, and commentary from the NPR archives. Each volume features sounds from nature, insights from experts and others who love the outdoor experience (naturalists, zoologists, biologists, adventurers, even a cowgirl), and vivid storytelling that captures the excitement of the wilderness.
