Touch-Self
Self-directed touching of the face (mouth, ear, trunk, tusk or temporal gland) or chest, with the fingers or tip of the trunk. Very often in the context of an interaction with another elephant, but may be seen in any context where an elephant appears uneasy or stressed. Likely analogous to the way we might scratch our head or rub our face when feeling socially or otherwise uncomfortable or unsure.
