Elephant(s) ‘running’ with a loose, floppy gait, shaking a lowered head from side-to-side, letting ears flap against the neck (Head-Waggling) and curling the tail up in Tail-Raising. Floppy-Running is often associated with trumpeting - in particular the Pulsated-Trumpet and Nasal-Trumpet.
This example shows an aggregation of elephants coming in from Amboseli’s Olodare area. At the road one of the elephants may have gotten frightened by a tourist vehicle, but that quickly transformed into an excuse for Floppy-Running en masse - adults and young alike. Several engage in Pulsated-Play-Trumpets. (Amboseli, Kenya)
