Covering nearly 1,000 species found in southern Africa (south of the Cunene and Zambezi rivers), this revised edition of Roberts Bird Guide features stunning new artwork detailing seasonal, age and sexual differences in approximately 240 annotated color plates, updated distribution maps, breeding and seasonality bars and concise but informative texts dealing not only with identification but aspects of biology such as food and voice. This new guide should be a valuable addition to any birder's library.
