Birds of North America (Kenn Kaufman Focus Guides) by Kenn Kaufmann, includes Kaufman's Advanced Birding guide.

Organized according to similarity of appearance and habitat, a new field guide to the birds of North America presents more than two thousand full-color photographs, digitally enhanced to reveal the field marks necessary for easy identification, accompanied by detailed descriptions, range maps, and a comparison of look-alike species.

Birders can memorize hundreds of details and still not be able to identify birds if they don't really understand what's in front of them.Today birders have access to almost too much information, and their attempts to identify birds can be drowned out by excess detail. The Kaufman Field Guide to Advanced Birding takes a different approach, clarifying the basics and providing a framework for learning about each group. Overall principles of identification are explained in clear language, and ten chapters on specific groups of birds show how these principles can be applied in practice. Anyone with a keen interest in identifying birds will find that this book makes the learning process more effective and enjoyable, and that truly understanding what we see and hear can make birding more fun.
