Red hartebeest (Alcelaphus buselaphus) have an excellent sense of smell and hearing, but their sense of sight is poor. When alarmed, they tend to mill about in seeming confusion, snorting nervously before running off. Once in its stride, a hartebeest can achieve a speed of 65km/hr, zigzagging left and right in its characteristic bouncing flight, which make it more difficult for predators to catch them.
