Effect of auxiliary males on territory ownership in the oribi and the attributes of multimale groups
Article Abstract:
The behavior of free-ranging oribi Ourebia ourebi was observed to find out if the formation of groups of the males indicate cooperative territory defense. Results reveal that a dominant male oribi welcomes the help of a subordinate oribi to defend its territory. In exchange, the subordinate auxiliaries are not evicted from their territory. Hence, overall results suggest that the formation of multimale oribi groups is their way of building a stronger defense through cooperation.

The economics of marking with faeces
Article Abstract:
A study was conducted to investigate if the constraint in feces production of the Ourebia ourebi affects the regulation of production and prioritization of the placement of feces marks of oribis. The behavior of oribis inhabiting Serengeti National Park in Tanzania was observed. Results indicate that male territorial oribis use feces marking more than juvenile males and females. Furthermore, their defecations are regulated in response to the limited supply of feces.

The maintenance of borders between male oribi
Article Abstract:
A study was conducted to determine the main function of the preorbital gland scent marking of territorial African antelopes called Ourebia ourebi. the behavior of oribis in Serengeti National Park, Tanzania was observed. Results indicate that male antelopes use scent marking mainly to defend their territories from rivals. Preorbital gland secretion level are highest when male oribis have many male neighbors.
