Pressing the forehead or upwardly-stretched trunk against the trunk of a tree and, in a series of sharp pushes, using the force of the entire body to shake the tree to release seedpods from its branches. This technique requires strength and, at least when large mature trees are concerned, is limited to adult males. Adult females have been observed to shake seedpods from smaller trees. The sound of falling seed pods attracts other elephants who feed alongside the tree shaker.
Just missed a shot of G7 shaking a tree to dislodge Faidherbia albida seed-pods. We see the seed pods falling from the tree. (Gorongosa, Mozambique)
