The Sibley Guide to Birds

David Allen Sibley, National Audubon Society. A. A. Knopf, $39.95 (544pp) ISBN 978-0-679-45122-8

The bird-watching world knows Sibley best as an immensely talented painter. His thick, attractive and data-packed color guide offers nearly 7,000 images, along with range maps and detailed descriptions of songs, calls and voices, for all the birds North Americans might see. It's a more informative volume than Kenn Kaufman's forthcoming Birds of North America (Forecasts, Sept. 11) but less portable and harder for beginners to use. An introduction describes the key parts of major classes of birdsDthe tomia and culmen of a gull's bill, the scapulars and coverts of passerines (songbirds). Sibley then moves on to hundreds of pages of birds in 42 categories, from Loons and Grebes to Silky Flycatchers and Bulbuls. A typical page has two columns, with one species in each: that species gets a color-coded range map, a description of its voice, and four to eight illustrative paintings. These multiple images of single species are the guide's most attractive feature; they let Sibley show some birds in several poses, as well as important seasonal and regional, juvenile and mature, breeding and nonbreeding, or male and female versions of the same bird. (Gulls, terns, and many other seabirds, in particular, change their patterns completely when breeding.) Sibley assists viewers by giving, on the same page, images of species that might be mistaken for one anotherDone column shows 13 kinds of thrushes. He also describes calls for every bird (not just the more common ones), and makes many more comparisons. If Kaufman's guide belongs in birders' coat pockets, Sibley's big, detailed book belongs on their desks; it's easy to imagine birders rushing to Sibley's guide to check details of plumage or to confirm an ID the smaller guide has helped them make.
