With the publication of the landmark volumes The Birds of South America: The Oscine Passerines and The Birds of South America: The Suboscine Passerines, Robert S. Ridgely and Guy Tudor established themselves as the leading authorities on the songbirds of South America. Reviewers hailed the volumes as the essential reference works for professional ornithologists and avocational birders alike, and they remain the only volumes that provide full scientific coverage of the continent's passerines.

Recognizing the need for a more compact guide that birders can take into the field, Ridgely and Tudor have now extracted and updated the essential identification information from The Birds of South America to create the Field Guide to the Songbirds of South America. This definitive guide is filled with indispensable features:

• 121 color plates that present Guy Tudor's magnificently detailed paintings of more than 1,500 species of songbirds, including more than 400 that were not illustrated in BOSA
• 160 additional color illustrations of subspecies and females
• Extensively updated color range maps for all of the species in the field guide, prepared by Robert S. Ridgely with technical assistance from Maria Allen and Terry Clarke, appear opposite the plates for each bird family
• Robert S. Ridgely's authoritative accounts of nearly 2,000 species that cover each bird's abundance, habitat, and range; elevational preference; taxonomic or nomenclatural changes; plumage description; general behavior and voice; and range beyond South America, if applicable

Birds of Ecuador comprehensively treats the nearly 1600 species of birds that can be found in mainland Ecuador. The authors describe Ecuador this way:

"One of the wonders of the natural world. Nowhere else is such incredible avian diversity crammed into such a small country. . . . Birds are, happily, numerous in many parts of Ecuador: even the downtown parks of the big cities such as Quito and Guayaquil host their complement."

Volume I, Status, Distribution, and Taxonomy, contains detailed information on the ecology, status, and distribution of all species. Introductory chapters deal with geography, climate, and vegetation; bird migration in Ecuador; Ecuadorian ornithology; endemic bird areas in Ecuador; and conservation. Individual species accounts treat habitat, distribution, and taxonomy.

Volume II, Field Guide, contains 96 full-color plates and facing pages of descriptive text, a color map of Ecuador, 2 line drawings of bird anatomy, 115 silhouette outlines, and nearly 1600 distribution maps. All species are illustrated in full color, including migrants and vagrants and visually distinctive subspecies. The text focuses on the field identification aspects of each species, including their behavior, vocalizations, and nest appearance.

The two volumes are available separately or may be purchased as a slipcased set....

This is the first paperback version of the second edition of the popular A Guide to the Birds of Panama. In the second edition, published in 1989, the authors expanded information on the birds of Costa Rica, Nicaragua, and Honduras: approximately 200 new species were added to the material in the 1976 edition. Over 300 additional species, some of them Panamanian, were illustrated. Sixteen new plates were added, and three of the original plates were replaced by improved versions. Throughout the book changes were made to accommodate the explosion in knowledge of the birds of Panama and nearby areas and of neotropical birds in general. The basic sequence and systematics of the AOU 1983 Check-list were adopted. Also included in the revised edition was expanded and updated information on birdfinding in Panama, prepared with the assistance of two of Panama's best resident birders. The book also contains a special section outlining developments in Panama ornithology and conservation.
