The Birds of Panama will be an essential tool for the new generation of birders traveling in search of Panama's spectacular avifauna.

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

A Bird-Finding Guide to Panama is an essential tool for anyone traveling in search of Panama's spectacular birds and natural attractions. With more than 970 species and a growing infrastructure of good roads, eco-lodges, and restaurants, Panama is a premier birding and nature tourism destination in the neotropics. The country's unique geography, small size, and varied habitats make it easy to see a vast diversity of birds within a short time. The isthmus is a crossroads for the hemisphere's birdlife Panama's varied avifauna includes such Central American specialties as the Resplendent Quetzal in its western highlands, while in the east, in San Blas and the Darien, species more characteristic of South America, such as the Blue-and-yellow Macaw, are found. Divided into three geographic sections (Canal Area, Eastern Panama, and Western Panama), this bird-finding guide provides comprehensive and up-to-date information on Panama's best birding sites. Features include detailed site descriptions, directions, road and trail maps, and bird lists, as well as listings of birder-friendly hotels and restaurants. In addition to a comprehensive species list for the country, the book also contains information on where to find more than 360 species of special interest."

The isthmus of Panama - where North and South America meet - is the permanent or migratory home of more bird species than all of North America, a total of 985 species This beautifully illustrated guide highlights over 140 familiar and unique species and includes a map featuring prominent bird-viewing areas. Laminated for durability, this lightweight, pocket-sized folding guide is an excellent source of portable information and ideal for field use by visitors and residents alike.www.waterfordpress.com

"Birds of Mexico and Central America features: The only field guide to illustrate and describe every species of bird in Central America from Mexico to Panama, including Belize, Guatemala, Honduras, El Salvador, Nicaragua, and Costa Rica; more than 1,500 species illustrated on 98 color plates; information on key identification features, habitat, and songs and calls; distribution maps showing location and prevalence of each species; illustrations of all plumages for each species, including males, females, and juveniles; informative notes conveniently placed opposite the illustrations; and comprehensive, concise, and highly portable."--BOOK JACKET.

Describing all of Colombia's birds, Steven Hilty and William Brown bring together information on one of the world's largest avifaunas-nearly 1,700 species. Over half of all the species of birds in South America are included, thus making the book useful in regions adjacent to Colombia, as well as in the country itself. The primary purpose of the work is to enable observers to identify the birds of the region, but it also provides detailed species accounts and will serve as an important handbook and reference volume. Fifty-six lavish color plates, thirteen halftone plates, and ninety-nine line drawings in the text illustrate over 85% of the species, including most of the resident birds. Notes on the facing-page of each place, and range maps of 1,475 species, facilitate identification. Written with the field observer in mind, the text gives special attention to comparisons of similar species, transcriptions of voices, and comments on behavior, status, and habitat. It also provides ranges, breeding data, and references. Notes outline taxonomic problems and briefly describe species that eventually may be found in Colombia. Introductory chapters and photographs highlight Colombia's geography, climate, and vegetation, and discuss migration and conservation questions, and the history of Colombian ornithology. Appendices contain a large bibliography, a section on birding locations, and coverage of two of Colombia's far-flung island territories, Isla San Andr s and Providencia. Maps depicting vegetation zones, political boundaries, national parks, and the most text localities are included.

The last decade has seen striking progress in the subject of renormalization in quantum field theory. The old subject of perturbative renormalization has been revived by the use of powerful methods such as multiscale decompositions; precise estimates have been added to the initial theorems on finiteness of renormalized perturbation theory, with new results on its large order asymptotics. Furthermore, constructive field theory has reached one of its major goals, the mathematically rigorous construction of some renormalizable quantum field theories. For these models one can in particular investigate rigorously the phenomenon of asymptotic freedom, which plays a key role in our current understanding of the interaction among elementary particles. However, until this book, there has been no pedagogical synthesis of these new developments. Vincent Rivasseau, who has been actively involved in them, now describes them for a wider audience. There are, in fact, common concepts at the heart of the progress on perturbative and constructive techniques. Exploiting these similarities, the author uses perturbative renormalization, which is the more widely known and conceptually simpler of the two cases, to explain the less familiar but more mathematically meaningful constructive renormalization. Originally published in 1991. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.
