Young noisy male elephant, maybe in musth, charging the vehicle. He got within about 6 feet (2 meters) before stopping. The ranger snapped his fingers and it startled the young guy and he turned and left shortly after the shot was taken. The reason I think he might have been in musth is his visible 5th leg :). Note that focal length was only 100mm, he was very close !
