Hyaena brunnea are found mainly along the coast while Crocuta crocuta range further inland being associated with Oryx gazeIIo and freshwater. Differences in latrines are descriptionbed and the scats or H. brunnea are significantly lighter than those of Crocuta (45,8 cf. 160,9; P<0,001). Analysis of identifiable prey remains showed that in H. brunnea scats Arctocephalus pussilus hair predominated (75%) cf. Crocuta scats in which Oryx gazelle hair (94,5%) predominated. Reasons for the geographical separation of the species are discussed. Keywords: Calcium content, Distribution, Food supply, Footprints, Habitats, Scats, Seal bulls, Social systems.
