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, the morning roar of the Guatemalan howler monkey, the seriously social laughing of the spotted hyena Guatemalan coatimundi, the honk of the courtship-crazed hammerhead bat, sophisticated conversation from the Central African forest elephant, the subtle bellow of the great plains bison, and many more intriguing sounds from creatures we seldom hear.

The NPR Sound Treks series brings the outdoors to life with 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.
