Ornithologist Debus offers this field guide to diurnal raptors found in Australia, complete with both artist drawings and color photographs of the birds identified. After an introduction to the definition, distinguishing characteristics, hunting and breeding habits and other behaviors of raptors, the guide proceeds with species descriptions including side-by-side visual comparisons of species with similar appearances. Then a "handbook" section discusses birds by taxonomic group and gives more detail on range, on endangerment and conservation. A glossary of relevant behavior, and ecological niches is included. The book ends with a brief section of terms. Distributed in the U.S. by Stylus Publishing. Annotation ©2013 Book News, Inc., Portland, OR (booknews.com)
