In this image the stallion is exhibiting herding or driving behavior. The posture is one of lowered head, stretched neck, ears pinned and sometimes a snake-like back and forth head movement. There is more intensity here demonstrated by the exaggerated low posture and fast gait; the stallion was feeling some sense of urgency to redirect the mares.
