This study looked at the drinking activity patterns and interactions of mammalian herbivores and carnivores at six of the 23 active waterholes at Etosha Heights Private Reserve, Namibia. The study provided a better understanding of drinking patterns and behaviour, as well as the interactions between herbivores and their predators at waterholes. Camera traps and a 48 hour game count at one were used to collect data at the waterholes. The results should enable the management team of the reserve to get a better understanding on the drinking activities of both herbivores and carnivores at Etosha Heights and to see which herbivore species overlap with or avoid which carnivore species at the waterholes. The results showed at what time of day or night different species preferred drinking.
