On this 2-CD audio guide you'll hear nearly 200 tracks featuring the hoots, screams, chitters, squawks, squeals, bill claps and barks of 19 regularly occurring species of North American owls and two rarities-the most comprehensive guide to owl vocalizations available.
Owls have a rich repertoire of sounds for communicating in the dark. A 56-page booklet with full-color images describes the wide variety of vocalizations made by each species. It will help birders identify these denizens of the night-from the ghostly Barn Owl, to the tiny Elf Owl, to the familiar Great Horned Owl. You'll gain a greater appreciation for owls and their sounds and behaviors.
