The endemic mountain nyala (Tragelaphus buxtoni) or balbok is an antelope found in high altitude woodland in a small part of central Ethiopia. Shy and elusive, it is a member of the Bovidae family, commonly known as the spiral-horned antelopes of Africa. Only males possess horns. Most of the Mountain Nyala are found in the Bale Mountains, where most of the southern slopes are densely forested. To avoid disturbance, it moves at night – but does appear in the morning and late afternoon to browse in grasslands.
