The first comprehensive collection of the calls and songs of these 1430 species - virtually all of the vocal ones in the region, including many species whose recorded sounds have never before been available. Birdcalls are of immense interest both to amateur and professional birds and ornithologists, especially since many birds can only be certainly identified from their call or song. A 150-page booklet is included with the disks, which provides a listing of the calls and recordist credits.
