- As in Peterson, Sibley employs a pointer system for key field markings--but additional text blurbs are included alongside the illustrations to facilitate identification.
- Descriptive passages on identification are more detailed than those in most other field guides. For example, Sibley includes extensive information on the famously hard-to-distinguish hawks in the genus Accipiter (sharp-shinned, Cooper's, and northern goshawk), noting differences in leg thickness and wing beat that will be of use to more advanced birders. A section on the identification of "peeps" (small sandpipers) includes tips about seasonal molting and bill length. Confusing fall warblers, Empidonax flycatchers, and Alcids receive similar treatment.
- As previously mentioned, ample space is given to illustrations that show plumage variations by age, sex, and geography within a single species. Thus, an entire page is devoted to the red-shouldered hawk and its differing appearances in the eastern U.S., Florida, and California; similarly, gulls are distinguished by age and warblers by sex.
- Range maps are detailed and accurate, with breeding, wintering, and migration routes clearly depicted; rare but regular geographic occurrences are denoted by green dots.
- The binding and paper stock are of exceptional quality. Despite its 544 pages, a reinforced paperback cover and sewn-in binding allow the book to be spread out flat without fear of breaking the binding.
Some birders will be put off by the book's size. Slightly larger than the National Geographic guide, it's less portable than most field guides and will likely spend more time in cars and desks than on a birder's person while in the field. For some it will be a strictly stay-at-home companion guide to consult after a field trip; others may want to have it handy in a fannypack or backpack. But regardless of how it is used, Sibley's Guide to Birds is a significant addition to any birding library. "Birds are beautiful," the author writes in the preface, "their colors, shapes, actions, and sounds are among the most aesthetically pleasing in nature." Pleasing, too, is this comprehensive guide to their identification. --Langdon Cook
Amazon Exclusive Essay: Author David Allen Sibley on Spring Birding in the United States

If you’re lucky enough to be able to travel to a place like Gray’s Harbor in Washington state, Cheyenne Bottoms in Kansas, or Delaware Bay in the east, you can see hundreds of thousands of migrating shorebirds as they stop for a few weeks to refuel on their way to the arctic. Along the Gulf Coast beaches you can see birds that have just flown from the Yucatan or from South America and are dropping into the nearest patch of cover to rest. Even in urban areas--places like Central Park in New York City, Rock Creek Park in Washington DC, Golden Gate Park in San Francisco, and countless other parks in cities and towns across North America--you will find outstanding birding. During spring migration these natural oases can be filled with brightly-colored songbirds, and seeing an exotic bird like a Blackburnian Warbler or a Western Tanager, where there were none the day before, is a thrill unique to birding. You don’t even have to travel. Whether you’re a seasoned birder or a neophyte, just grab some binoculars and a bird guide, and head out to your backyard, or to your local park or beach to see what’s happening. Those warm spring days when all you want to do is take a long lunch break and sprawl out on the lawn are the same days that the birds will be migrating north, and all you have to do is look up.
