The symposium, held in 1979 at the University of Cape Town, commemorates the 50th anniversary of the Southern African Ornithological Society and the 150th anniversary of the University. Quite expectedly, participants were predominantly South African, with a few Europeans and Americans. Thirty-seven presentations, plus a summary, were given at the meeting, but only 26 papers were published; the rest had Abstracts only. The book is divided into five subject areas: Feeding Ecology (6 papers), Patterns of Distribution (5 papers), Distribution Studies (4 papers), Conservation of Species and Habitats (6 papers), and Physiology and Breeding Biology (5 papers).
