The mating behaviour of the tsessebe (Damaliscus lunatus lunatus) in the Kruger National Park.

The mating behaviour of tsessebe was observed in the Kruger National Park. A description of the typical sequences in the mating behaviour is given which includes the "nose and neck stretch" posture of the courtship display of the bull when approaching a cow, the role of olfactory stimuli which are derived from either smelling at the base of a cow's tail or from the ground where a cow had been laying down or urinated, the spontaneous ejaculation of the bull in response to such stimuli and mounting. Distinction is drawn between the dominance display ("nose forward-upward posture") and the courtship display of the tsessebe bull. Comparative notes on the mating behaviour of congeneric species, i.e. the blesbok (D. dorcas phillipsi), bontebok (D. d. dorcas) and topi (D. lunatus korrigum) are given. Many similarities are evident despite a number of dissimilarities. Attention is also paid to confliction interpretations of the courtship displays in the different species.
