A combination call that consists of a Rumble followed by a Roar and then a Rumble without an inhalation (see Roar). Roars that occur during intense social excitement such as during a greeting ceremony, the birth of a calf, or in response to the arrival of a musth male may occur as a Rumble-Roar-Rumble. Similarly, the roars of a lost calf may often be in the form Rumble-Roar-Rumble, though the quality of these is different from those occurring in a social context.
A 1 year calf suckles from a young female (with small breasts) and then stops midway to gives a Rumble-Roar-Rumble and then another loud throaty Rumble. It appears that the calf listens before calling. It is possible that the female he is Suckling from is not his mother and that he is calling to his mother who is out of sight. Alternatively he is not getting enough milk and is complaining, but the call does not have quite the right tone for than. The adult female also Rumbles as we can see by her Ear-Flapping. He resumes Suckling. (Maasai Mara, Kenya)
