"Sasol Birds of Southern Africa" remains the region's most comprehensively illustrated and trusted field guide. This fourth edition has been greatly improved by the addition of group introductions, calendar bars showing species' occurrence and breeding periods, a section on 'how to use this book', as well as sonograms depicting the calls of tricky bird groups. The newly designed plates are meticulously illustrated, with labels pinpointing key differentiating features. Distribution maps show the relative abundance of a species in the region and also indicate resident or migrant status. Written by top birders, this authoritative and comprehensive identification guide is invaluable to all birders.
