Another car told our ranger that their was an 'angry elephant' ahead, so we decided to go and check it out. You are not supposed to run away from elephants, so that they don't get used to chasing cars. This elephant, however, was masting (in heat) and was looking for a mate. We didn't want to have 'relations' with this elephant, so we decided to let him be...he did somewhat chase our vehicle for a short distance.
When elephants get mad they flare their ears out...he looked pretty ticked off.
