During the approaching mating period, a territorial bull rhino will join the female for up to 20 days. At first he accompanies the female by keeping a fair distance until she comes into full oestrus and allows him to approach.

The courtship lasts up to a day, characterized by the male resting his chin on the female’s rump and attempted mounting (0:00). Finally, the cow will stand still, with tail curled, and allow copulation. Mating is remarkably prolonged, lasting from 20 minutes to one hour.
