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. "A sophisticated treatment of one of the world's richest avifaunas."--The Quarterly Review of Biology

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.
