Garrett, Ornithology Collections Manager, Natural History Museum of Los Angeles County "The best birding field guide you can buy...National Geo 6 is now my default go-to guide.

"-Minneapolis Star Tribune blog" "Shelve all your other field guides for Dunn and Alderfer's brand-new sixth edition, which leaps beyond previous editions, as well as all competition...Study it at home. Carry it afield. It has no peer." -Daniel Gibson (birding expert), Amazon.com "This new, sixth edition is by far the best of this splendid guide's incarnations so far.
