SUMMARY: Birds of Peru is the most complete and authoritative field guide to this diverse, neotropical landscape. It features every one of Peru's 1,817 bird species and shows the distinct plumages of each in 307 superb, high-quality color plates. 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.
