Open encyclopedia reference
The Ruwenzori duiker or Ruwenzori red duiker (Cephalophus rubidus) is a stocky but small antelope found only in the Ruwenzori Mountains between Uganda and, probably, the Democratic Republic of Congo. They may be a subspecies of the black-fronted duiker or the red-flanked duiker.
The Ruwenzori duiker weighs about 15 kg (33 lb) and has a shoulder height of about 45 cm (18 in). They have rufous coats, lighter on their underbellies and darker on their backs. Their short, prong-like horns are about 8 cm (3.1 in) long.
They are found in subalpine zones above 3,000 metres (9,800 ft), where they eat herbs. They are diurnal.
