Context: Affiliative (1)

Another adult female in the group walks toward Lorato and Mama Little E and Mama Little E displays Head-Raising and Ear-Lifting in a typical Little-Greeting posture. We can hear a Rev-like sound by her and then, another immediately after by the female in the foreground who approached her and also Head-Raises and Ear-Lifts. Normally this would be associated with rumbling, but we see no evidence of this. They stand side-by-side, but it is also clear that this is a Supplant.

The older female came very purposefully and displaced Mama Little E from where she was feeding. As this goes on Lorato looks after Little E. Note that we have called this a Rev since the sounds came from the elephants' mouths not from their trunks. (Maasai Mara, Kenya)
