Roberts Birds of Southern Africa has been continuously in print for some 65 years and is the most popular African natural history book of all time. The scope and depth of biological information in the Seventh edition of Roberts far exceeds that of any previous edition. It covers all 951 species recorded in the region and also illustrates these in 80 new plates commissioned from the region’s best bird artists. For scientists and conservationists it is a benchmark publication and will be a standard reference for years to come. For birdwatchers it will be an invaluable source of information to help them better understand and appreciate the birds around them.
