Trunk-Bounce-Drag

An elephant dragging and occasionally slightly bouncing the distal and outer portion of a curled trunk on the ground making a rasping sound; often leaves a continuous or intermittent snake-like mark on the ground. Musth males, particularly, may drag and bounce their trunks along the ground for long distances (3 kilometers has been observed) when Walking or Tracking another elephant; musth males and elephants of both sexes may drag their trunks on the ground as a threat at very close range.

Trunk-Bounce-Drag

Context: Attacking & Mobbing (1)

This is a 2 minute Charge by Valente, gf0013, (followed by the others in a Group-Charge) who takes over from Marcela, gf0017, who took over from Mwana Nzo, gf0016, who led the first Charge after Provocadora initiated the Group-Charge. Note Valente’s Ear-Spreading throughout. She does a lot of Trunk-Bounce-Drag (only parts of which are marked) and gives a couple of Trumpet-Blasts that are not very effective - perhaps due to her physical effort. At one point she pauses Reaching-High as if her job is complete, but then renews her Charge trying to cut us off as we turn. She clearly understands the arc of our movement and how to best catch us. When she finally figures she has done her job she stops and goes to meet the others who are coming up behind her. It is at this point they have the End-Zone-Dance. (Gorongosa, Mozambique)

Valente, gf0013, leads a Group-Charge. As she Charges she lowers her head and drags and bounces her trunk along the ground in a Trunk-Bounce-Drag and ends with a Forward-Trunk-Swing. Each Forward-Trunk-Swings is associated with what she intends to be a Trumpet-Blast, though it comes out as more of a Snort. She returns to her family and they Bunch together and vocalize.
