For these beginning and intermediate enthusiasts, National Geographic Birding Essentials is a must. Comprehensive and authoritative, yet engaging and user-friendly, it teaches readers how to begin and improve their birding... what to look and listen for... and how to make sense of what they see and hear.

National Geographic's quality photography is a major highlight of the book, supplemented by pencil drawings and full-color maps to give the novice and intermediate birder a full range of visual information.Field Ornithologists Jonathan Alderfer and Jon Dunn have crafted a masterful guide, striking just the right balance of practical information and reader-friendly tone. Chapters discuss the pleasures of birding, equipment needed, how to read range maps, birds' physical features, how to identify birds, identification challenges, bird classification and suggested books and journals for building a fine birding library.National Geographic has established a stellar reputation among birders with our blockbuster Field Guide to the Birds of North America. The tradition continues as we serve an entry-level market that continually needs the helpful, up-to-the-minute information found in National Geographic Birding Essentials.
