This is an excellent field guide on birds, based on a new series of the Bird Lore leaflets. Mr. Peterson is the director of the educational program of the National Association of Audubon Societies, and the author of the Field Guide to the Birds, from which the illustrations for this junior volume are drawn. He has chosen twenty three birds, including some familiar ones such as the house wren, the blue bird and the blue jay, but for the most part the birds selected are not the routine ones. For instance, there is the redshouldered hawk, the burrowing owl, the ruby-throated humming bird, the cedar waxwing, the bobolink, the Baltimore oriole, etc. Colored full page illustrations, marginal pen and ink drawings, and brief data as to nests, locality, value, songs, and habits make this a valuable bird guide.
