Description

The springbok is a slender antelope with long legs and neck. Both sexes reach at the shoulder with a head-and-body length typically between . The weights for both sexes range between . The tail, long, ends in a short, black tuft. Major differences in the size and weight of the subspecies are seen. A study tabulated average body measurements for the three subspecies. ''A. m. angolensis'' males stand tall at the shoulder, while females are tall. The males weigh around , while the females weigh . ''A. m. hofmeyri'' is the largest subspecies; males are nearly tall, and the notably shorter females are tall. The males, weighing , are heavier than females, that weigh . However, ''A. m. marsupialis'' is the smallest subspecies; males are tall and females tall. Average weight of males is , while for females it is . Another study showed a strong correlation between the availability of winter dietary protein and the body mass. Dark stripes extend across the white face, from the corner of the eyes to the mouth. A dark patch marks the forehead. In juveniles, the stripes and the patch are light brown. The ears, narrow and pointed, measure . Typically light brown, the springbok has a dark reddish-brown band running horizontally from the upper foreleg to the edge of the buttocks, separating the dark back from the white underbelly. The tail (except the terminal black tuft), buttocks, the insides of the legs and the

are all white. Two other varieties – pure black and pure white forms – are artificially selected in some South African ranches. Though born with a deep black sheen, adult black springbok are two shades of chocolate-brown and develop a white marking on the face as they mature. White springbok, as the name suggests, are predominantly white with a light tan stripe on the flanks. The three subspecies also differ in their colour. ''A. m. angolensis'' has a brown to tawny coat, with thick, dark brown stripes on the face extending two-thirds down to the

. While the lateral stripe is nearly black, the stripe on the rump is dark brown. The medium brown forehead patch extends to eye level and is separated from the bright white face by a dark brown border. A brown spot is seen on the nose. ''A. m. hofmeyri'' is a light fawn, with thin, dark brown face stripes. The stripes on the flanks are dark brown to black, and the posterior stripes are moderately brown. The forehead patch, dark brown or fawn, extends beyond the level of the eyes and mixes with the white of the face without any clear barriers. The nose may have a pale smudge. ''A. m. marsupialis'' is a rich chestnut brown, with thin, light face stripes. The stripe near the rump is well-marked, and that on the flanks is deep brown. The forehead is brown, fawn, or white, the patch not extending beyond the eyes and having no sharp boundaries. The nose is white or marked with brown. The skin along the middle of the dorsal side is folded in, and covered with white hair erected by

s on both sides of either jaw, rather than the three observed in gazelles. This gives a total of 28 teeth in the springbok, rather than 32 of gazelles. Other points of difference include a longer, broader, and rigid bridge to the nose and more muscular cheeks in springbok, and differences in the structure of the horns. Both sexes have black horns, about long, that are straight at the base and then curve backward. In ''A. m. marsupialis'', females have thinner horns than males; the horns of females are only 60 to 70% as long as those of males. Horns have a girth of at the base; this thins to towards the tip. In the other two subspecies, horns of both sexes are nearly similar. The spoor, narrow and sharp, is long.


Ecology and behaviour

Springbok are mainly active around dawn and dusk. Activity is influenced by weather; springbok can feed at night in hot weather, and at midday in colder months. They rest in the shade of trees or bushes, and often bed down in the open when weather is cooler. The social structure of the springbok is similar to that of

males round up female herds that enter their territories and keep out the bachelors; mothers and juveniles may gather in nursery herds separate from harem and bachelor herds. After weaning, female juveniles stay with their mothers until the birth of their next calves, while males join bachelor groups. A study of vigilance behaviour of herds revealed that individuals on the borders of herds tend to be more cautious, and vigilance decreases with group size. Group size and distance from roads and bushes were found to have major influence on vigilance, more among the grazing springbok than among their browsing counterparts. Adults were found to be more vigilant than juveniles, and males more vigilant than females. Springbok passing through bushes tend to be more vulnerable to predator attacks as they can not be easily alerted, and predators usually conceal themselves in bushes. Another study calculated that the time spent in vigilance by springbok on the edges of herds is roughly double that spent by those in the centre and the open. Springbok were found to be more cautious in the late morning than at dawn or in the afternoon, and more at night than in the daytime. Rates and methods of vigilance were found to vary with the aim of lowering risk from predators. During the rut, males establish territories, ranging from , which they

by urinating and depositing large piles of dung. Males in neighbouring territories frequently fight for access to females, which they do by twisting and levering at each other with their horns, interspersed with stabbing attacks. Females roam the territories of different males. Outside of the rut, mixed-sex herds can range from as few as three to as many as 180 individuals, while all-male bachelor herds are of typically no more than 50 individuals. Harem and nursery herds are much smaller, typically including no more than 10 individuals. In earlier times, when large populations of springbok roamed the

(derived from the Afrikaans ''pronk'', "to show off") or stotting. In pronking, the springbok performs multiple leaps into the air in a stiff-legged posture, with the back bowed and the white flap lifted. When the male shows off his strength to attract a mate, or to ward off predators, he starts off in a stiff-legged trot, leaping into the air with an arched back every few paces and lifting the flap along his back. Lifting the flap causes the long white hairs under the tail to stand up in a conspicuous fan shape, which in turn emits a strong scent of sweat. Although the exact cause of this behaviour is unknown, springbok exhibit this activity when they are nervous or otherwise excited. The most accepted theory for pronking is that it is a method to raise alarm against a potential predator or confuse it, or to get a better view of a concealed predator; it may also be used for display. Springbok are very fast antelopes, clocked at . They generally tend to be ignored by carnivores unless they are breeding.

''. Springbok can meet their water needs from the food they eat, and are able to survive without drinking water through dry season. In extreme cases, they do not drink any water over the course of their lives. Springbok may accomplish this by selecting flowers, seeds, and leaves of shrubs before dawn, when the food items are most succulent. In places such as Etosha National Park, springbok seek out water bodies where they are available. Springbok gather in the wet season and disperse during the dry season, unlike other African mammals.


Reproduction

The female keeps her calf hidden in cover while she is away. Mother and calf rejoin the herd about three to four weeks after parturition; the young are weaned at five or six months. When the mother gives birth again, the previous offspring, now 6 to 12 months old, deserts her to join herds of adult springbok. Thus, a female can calve twice a year, and even thrice if one calf dies. Springbok live for up to 10 years in the wild.

and northward to southern Angola and Botswana. In Botswana, they mostly occur in the Kalahari desert in the southwestern and central parts of the country. They are widespread across Namibia and the vast grasslands of the Free State and the shrublands of Karoo in South Africa; however, they are confined to the Namib Desert in Angola. The historic range of the springbok stretched across the dry grasslands, bushlands, and shrublands of south-western and southern Africa; springbok migrated sporadically in southern parts of the range. These migrations are rarely seen nowadays, but seasonal congregations can still be observed in preferred areas of short vegetation, such as the Kalahari desert.

National Parks and a number of provincial reserves in South Africa. In 1999, Rod East of the IUCN SSC Antelope Specialist Group estimated the springbok population in South Africa at more than 670,000, noting that it might be an underestimate. However, estimates for Namibia, Angola, Botswana, Transvaal, Karoo, and the Free State (which gave a total population estimate of nearly 2,000,000 – 2,500,000 animals in southern Africa), were in complete disagreement with East's estimate. Springbok are under active management in several private lands. Small populations have been introduced into private lands and provincial areas of
