Winner, Award of Merit in Design, Southern Books Competition, Southeastern Library Association A land of incredible natural resources, the South American continent is rich in plant and animal species. Among birds alone, over 3,100 species are either resident or migrant. Birds are some of South America's treasures and also one of its most endangered resources. Hence the need for a descriptive record of South American birds that will serve both professional and amateur bird students and encourage conservation of these magnificent species. Although South American birds elicit much popular and scientific interest, they have never been completely or satisfactorily described and cataloged in a single, published source. The Birds of South America, projected to be a four-volume work, thus fills a critical void. Starting from a museum approach, the authors have examined specimens of each subspecies, comparing them visually and trying to discern the patterns in their plumage variation, both intra- and inter-specifically. They take a new look at bird systematics, reassessing relationships in light of new information. Perhaps most important, they combine this review and analysis with extensive field observations to give an accurate, incisive portrait of the birds in nature. At a time when rapid development is devastating millions of acres of tropical habitat in South America, this record of an endangered resource becomes crucial. If the birds and other plants and animals of South America are to be saved, they must first be known and appreciated. The Birds of South America is a major step in that direction. Volume I includes the Jays and Swallows; Wrens, Thrushes, and Allies; Vireos and Wood-warblers; Tanagers, Icterids, and Finches. The remaining volumes of The Birds of South America will be: Volume III: The Nonpasserines (Landbirds) Volume IV: The Nonpasserines (Waterbirds) No release date has been set for the remaining volumes.

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.

Brazil is the fifth largest country in the world and is one of the planet's richest places for bird diversity, especially when it comes to the number of endemic species. Brazil's Atlantic Forest region is one of the most dazzling of all. Immediately surrounding São Paulo and Rio de Janeiro, this area of Brazil is also a relatively accessible area to birders from around the world. In the Birds of Brazil Field Guides, the Wildlife Conservation Society brings together a top international team to do justice to the incredible diversity of Brazilian birds. This second guide presents 927 bird species, 863 illustrated, that occur in just the southeastern Atlantic Forest biome (Mata Atlântica in Portuguese). Of these species, 140 are endemic and 105 near endemic to just this region; 83 of these are threatened. Modern and compact, this field guide provides illustrations of unparalleled quality, key field marks, and regional range maps to facilitate easy recognition of all species normally occurring in this vibrant and critically important area of Brazil.
