Written by two of the leading explorers in the birdlife of the High Andes, this book sets new standards in this field. The book is illustrated by Jon Fjeldsaa, one of the World's most gifted bird artists, who again has proved his accuracy with the fine plumage details as well as masterly renditions of the general impression and shape. Almost one tenth of the World's nine thousand bird species are illustrated, many of them for the first time. Both males, females, young, and distinct subspecies are shown. The 64 beautifully composed colour plates depict over two thousand plumages. This is supplemented by several hundred line-drawings of the birds. Today this book is regarded as the "bible" in Andean birds and more than 4000 copies have been sold. Birds of the High Andes is published in co-operation with the Zoological Museum, Copenhagen, where one third of the retail price for the books is spent on further investigations in Andean birds. A colour prospectus is available upon request. 64 colour plates. Numerous line drawings. Distribution map to each species.

The ultimate field guide to the birds of Argentina, an indispensable companion for any traveller to the region. This spectacular new field guide is the ultimate reference to the birds of Argentina and the islands of the South-west Atlantic, essential for researchers, birders and conservationists alike. It covers Argentina and all Fuegian and Hornean islands south to the Diego Ramírez Islands and east to the Falklands. More than 2,300 images illustrate 1,075 species, including all residents, migrants and most vagrants. This authoritative book includes 199 stunning colour plates, depicting every species and many distinct plumages and subspecies, including 28 endemics and 17 near-endemics. Concise text describes key identification features, status, range, habitats and voice, with up-to-date colour distribution maps for each species.

An illustrated survey of the world's most endangered birds This illustrated book vividly depicts the most endangered birds in the world and provides the latest information on the threats each species faces and the measures being taken to save them. Today, 571 bird species are classified as critically endangered or endangered, and a further four now exist only in captivity. This landmark book features stunning photographs of 500 of these species—the results of a prestigious international photographic competition organized specifically for this book. It also showcases paintings by acclaimed wildlife artist Tomasz Cofta of the 75 species for which no photos are known to exist. The World's Rarest Birds has introductory chapters that explain the threats to birds, the ways threat categories are applied, and the distinction between threat and rarity. The book is divided into seven regional sections—Europe and the Middle East; Africa and Madagascar; Asia; Australasia; Oceanic Islands; North America, Central America, and the Caribbean; and South America. Each section includes an illustrated directory to the bird species under threat there, and gives a concise description of distribution, status, population, key threats, and conservation needs. This one-of-a-kind book also provides coverage of 62 data-deficient species.

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.

It follows naturally from the widely accepted Darwinian dictum that failures of populations or of species to adapt and to evolve under changing environments will result in their extinction. Population geneti cists have proclaimed a centerstage role in developing conservation biology theory and applications. However, we must critically reexamine what we know and how we can make rational contributions. We ask: Is genetic variation really important for the persistence of species? Has any species become extinct because it ran out of genetic variation or because of inbreeding depression? Are demographic and environmental stochas ticity by far more important for the fate of a population or species than genetic stochasticity (genetic drift and inbreeding)? Is there more to genetics than being a tool for assessing reproductive units and migration rates? Does conventional wisdom on inbreeding and "magic numbers" or rules of thumb on critical effective population sizes (MVP estimators) reflect any useful guidelines in conservation biology? What messages or guidelines from genetics can we reliably provide to those that work with conservation in practice? Is empirical work on numerous threatened habitats and taxa gathering population genetic information that we can use to test these guidelines? These and other questions were raised in the invitation to a symposium on conservation genetics held in May 1993 in pleasant surroundings at an old manor house in southern Jutland, Denmark.

The best guide to the birds of Peru—now in a revised paperback edition Birds of Peru is the most complete and authoritative field guide to this diverse, neotropical landscape.

Concise descriptions and color distribution maps are located opposite the plates, making this book much easier to use in the field than standard neotropical field guides. This fully revised paperback edition includes twenty-five additional species. A comprehensive guide to all 1,817 species found in Peru—one fifth of the world's birds--with subspecies, sexes, age classes, and morphs fully illustrated Designed especially for field use, with vivid descriptive information and helpful identification tips opposite color plates Detailed species accounts, including a full-color distribution map Includes 25 additional species not covered in the first edition Features 3 entirely new plates and more than 25 additional illustrations
