This field guide describes and illustrates all 2,100 species of birds occurring in sub-Saharan Africa, a remarkable feat. The 359 color plates, excellent range maps and brief descriptions are integrated on facing pages for easy reference. It's especially useful for those Southern African countries without their own field guides. It also covers Socotra, Pemba, and the islands in the Gulf of Guinea (It does not, however, cover Madagascar). The large color paintings are by Norman Arlott, Peter Hayman, and Alan Harris.  (SAF143, $49.50)
