This title contains updated text and includes an additional fifteen new species that have been recognised since the publication of Sasol Birds. The new edition incorporates the most recent information about bird taxonomy, as well as the latest bird names based on recommendations of the international ornithological committee. All distribution maps have been revised and feature dual shading to show relative abundance of a species in the region, as well as crosses to indicate the occurrence of vagrants. Numerous illustrations have been updated and revised where necessary. The essays on identifying problem species have also been revised and updated to bring the book in line with international birding developments.
