Each tape groups bird species according to acoustic similarity in order to help you learn the basics of bird-song identification. Soon you'll know just by listening whether the bird skulking underneath the bushes is  an orange-crowned warbler, a chipping sparrow, or a dark-eyed junco.--This text refers to an out of print or unavailable edition of this title.
