During the periods of full moon from May to October 1980, black rhinoceroses were censused at all the important waterholes in the Etosha National Park. Identification based on anatomical features (particularly horns and notches in ears), group composition and behaviour, revealed a population of at least 350 rhinoceroses of which 45 - 50% occurred in the west of the park. This technique is effective in areas where rhinoceroses need to drink at established water-points and it was shown to be up to 70% more accurate than census by helicopter. In addition, information is obtained on behaviour, inter- and intraspecific relationships and population dynamics.
