Sibley soars to excellence yet again. Based on his previous volume, The Sibley Guide to Birds, these smaller regional editions provide the portability that birders require. All the qualities to be expected in a field guide are here: concise species description (status, habitat, behavior, and voice), comparisons with similar species, field marks, range maps, the inclusion of exotics, and a good binding (able to withstand both field and rugged armchair testing). Image reproduction is crisp, colors are distinct, shading shows well, and despite the very small size, range map colors are clear. A detailed index (which includes both common and scientific name) and a quick index with family-level common names (e.g., owl, sparrow, and gull) provide additional access. Sibley has accomplished the difficult task of condensing his previous guide to practical field size. Consider these essential purchases for all collections.
