The first field guide ever published on the world's most important birding country, and fills a huge gap in our knowledge of South American ornithology. Peru harbors almost 1,800 species of birds, including 118 endemics, in every habitat ranging from coast and deserts to 23,000-foot snow-capped Andean peaks, intermontane valleys, lush cloud forests and tropical rainforests. Almost all 1,800 of the species are illustrated on the 127 color plates included in this extensive guide. The text describes the main identification features of each species, plus its range in Peru, preferred habitat, and worldwide range.
