This remote site lies on the eastern slope of the Andes on the upper reaches of the Amazon basin in a region exhibiting a rich diversity of flora and fauna. With the publication of this Field Guide to the Birds of Machu Picchu and the Cusco Region, visitors from all over the world can now appreciate and identify the birds of the mountains, valleys, and forests of this World Heritage Site. The Field Guide to the Birds of Machu Picchu and the Cusco Region is the result of a unique, three-continent collaboration between Barry Walker in Peru, Buteo Books in Virginia (USA), and Lynx Edicions in Barcelona. The text from previous versions of Barry Walker’s field guide has been completely rewritten and updated. Covering the nearly 500 species known to occur in the region, the individual species accounts provide details on habitat, behavior, vocalizations, and occurrence. The 82 color plates on pages facing the text are drawn from illustrations painted for the monumental Handbook of the Birds of the World. This is a field guide with all the essentials to identify the bird in the field, yet compact and light enough to fit in a pocket or carry on the Inca Trail. A section of the book contains a detailed guide to the best birding sites in the region and an annotated checklist, both of which will be of great value to the visiting birdwatcher.
