This five-volume set devoted to birds is a subset of a 20-volume set — which derives material from the eminent 17-volume adult reference recently issued in a second edition. The student set presents material in an attractive, standardized format appropriate for middle school students and above, and for general readers seeking basic information. Each entry includes physical characteristics, habitat, behavior, range, conservation status, and relationship to people, as well as resources (books, periodicals, web sites) for further information. Range maps and color photos support the text; and each volume includes a pronunciation guide for scientific names and a glossary.
