"The Mountain Reedbuck averages 75 cm at the shoulder, and weighs around 30 kg. It has a grey coat with a white underbelly and reddish-brown head and shoulders. The male has ridged horns of around 35 cm, which curve forwards"Reedbuck:
Southern Reedbucks average 85 cm at the shoulder, and weigh around 70 kg. They have grey-brown coats with a white underbelly and black forelegs. Males have ridged horns of around 35 cm, which grow backwards and then curve forwards.Oribi:
"Oribi grow to around 92–110 cm (36 to 43 inches) in length, with a shoulder height of 50–66 cm (20 to 26 inches) and weigh an average of 12–22 kg (26 to 49 lb). They can run at speeds of up to 40–50 km/h (25–31 mph). In captivity they have a lifespan of up to 14 years.
The back and upper chest is yellow to orange-brown. The chin, throat, chest, belly and rump are white. The tail is short and bushy, the upper side black or dark brown, and the under surface white. The white crescent-shaped band of fur above the eye is a characteristic that helps to distinguish this species from other similar-looking antelope. Below each ear is a large round black glandular patch, the nostrils are prominently red, and on the sides of the face are vertical creases that house the pre-orbital glands. These glands produce an odorous secretion that is used to mark the oribi's territory. Only males grow horns, which are slender and upright, ridged to about halfway up, the ends being smooth and pointed, with some of length 19 cm (7.5 inches) being recorded"Sharpe's Grysbok:
"It is similar in size to the Gray Duiker, but has a stockier body and elongated fur over the hindquarters. It stands about 20" (45–60 cm) at the shoulders and weighs only 7–11.5 kg. Its coat is reddish-brown which is streaked with white; eye-rings, around mouth, throat and underside are off-white. The males have stubby horns, which are widely spaced. Sharpe's Grysbok has a short deep muzzle with large mouth and heavy molar (grinding) teeth. The short neck and face on a long-legged body result in a high-rump posture when browsing."Female bushbuck:
The female has no horns and has a reddish brown coat with white spots and has a short bushy tail
"Lichtenstein's Hartebeest typically stand about 1.25 m (4 ft) at the shoulder and have a mass of around 150 kg (330 lb). Lichtenstein's Hartebeest are a red brown colour, which is lighter on the underbelly. The horns found on both sexes appear from the side to be shaped like the letter 'S' and appear from the front to be shaped like the letter 'O' with its upper portions missing. The horns are slightly ridged and reach over 0.5 m in length."Common Duiker:
"Colouration of this species varies widely over its vast geographic range. There are thought to be as many as 19 subspecies ranging from chestnut in forested areas of Angola to grizzled gray in northern savannas and light brown shades in arid regions. It grows to about 20 inches (50 cm) in height and generally weighs 12 to 25 kg; although females are generally larger and heavier than their male counterparts. The male bears horns which can grow to 4.25 inches (11 cm) long."
