Ethiopian wolves have twice been observed to feed on rock hyraxes and mountain nyala calves. The leopard is the main predator of the mountain nyala. The nyala and the mountain nyala are African antelopes. The lifespan of a mountain nyala is around 15 to 20 years. The mountain nyala is a large sexually dimorphic bovid. The mountain nyala are shy and elusive towards human beings. The nyala and mountain nyala often regularly appear on walls, commercial products and tourist curios. Primarily a browser, the mountain nyala may switch to grazing occasionally. Hence the mountain nyala forms a monophyletic clade with these three species. The mountain nyala was first described by English naturalist Richard Lydekker in 1910. The mountain nyala breed throughout the year, but the peak occurs in December. Mountain nyala are hunted by humans, for instance, by the Oromo people. The mountain nyala is featured on the obverse of the Ethiopian ten cents coin. Kuni-Muktar Mountain Nyala Sanctuary is a protected area and wildlife sanctuary in Ethiopia.
