Male nyala (Tragelaphus angasii) performing a lateral display. Adversaries circle each other when presenting with their faces trained to the ground, using their peripheral vision to monitor their opponent. In an attempt to make themselves appear as big as possible they fluff up their tails and the dorsal manes on their back, whilst arching their heads forward with horns poised. Nyala are antelopes that are found in dense bush near water in southern Africa. Males (bulls) have horns whilst the females have no horns. Nyala are grazers and browsers and eat a wide variety of vegetation. Photographed in the Kruger National Park, South Africa.
