Grasping a trunkful of grass and then using the tip of the trunk to repeatedly roll it against the underside of the trunk to pack it together into a size and shape that is convenient to put in the mouth without dropping blades onto the ground. This takes experience to perfect. It is regularly employed by adults, but calves are more clumsy.
Two females, a tuskless juvenile and a tuskless calf, are feeding on grass. The younger one is using a Pack-grass technique. (Amboseli, Kenya)
