I like "Newmans Birds of Southern Africa" by Kenneth Newman or Ian Sinclairs "Field Guide Birds of Southern Africa". Either one covers most of the birds of Southern Africa. They cover birds only, no mammels. For mammels I use Collins Field Guide Larger Mammels of Africa by Jean Dorst & Pierre Dandelot. There is also a good Pocket-guide to Southern African Birds by Burger Cillie & Ulrich Oberprieler. I'm sure there are many others but hese are the ones I use. I do love birding in Africa.
