The body and extremities suddenly cease moving and the elephant Stands Head-Raising and Ear-Spreading with Ears-Stiff. The elephant may swing its head from side to side, Head-Swinging, as if to localise a sound. An individual rarely stands stock still except when Listening or Resting, usually some part of the body, ears, trunk, tail is in motion. Listening may be distinguished from Resting, during which an elephant relaxes it's head and ears allowing its head to hang below its shoulders and its ears to flop forward. All age/sex group may be observed Listening.
