Alternatively Walking a few steps and then standing idly while Waiting for other elephants to either catch up or to initiate movement; contextually this posture is obvious as the Waiting individual is attentive (J-Trunk, Eye-Blinking, Ears-Stiff), often glancing back over her shoulder (Look-Back), and/or checking the others' activity by sniffing, Listening and Looking, and indicating her impatience by taking a few desultory steps and pausing again - Walk-Wait.
Members of the V family are Waiting to depart, but their matriarch, Valda (marked with an M), is not. They have been standing Body-Axis-Pointing southeast, while she has been facing northwest. All are listening and I can see there is Rumbling because ears are flapping. Valda turns Body-Axis-Pointing southeast, but still does not move. She pauses and they Wait again, alert. Valda is Listening again.
The others are getting frustrated. They stand and Wait and Wait - alert. Valda has turned Body-Axis-Pointing northwest again. Then Vigilante begins to walk NW and the others follow her. She walks until she is parallel with Valda and stops. They wait. And wait and wait. The camera zooms in so we can't see Valda. Finally one of the younger one turns and all turn. The camera zooms out and Valda has turned Body-Axis-Pointing SE with the others and I think she initiated this turn. But again Valda stops and waits.
There is some Walk-Wait movement by the others until finally Valda moves and all begin walking SE. All are moving in direction of the river, pausing now and then to grab a mouthful of grass. Decision-making elephant style. Gorongosa, Mozambique)
