Hardback. Zustand: Good. 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.…

Paperback. Zustand: Good. 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. …
