Springbok SPRINGBOK Antidorcas marsupialis German:Springbock French:Springbok Spanish: Gacela saltarina Breeding Mating season: May breed at any time but tied to rains Gestation: 168 days Measurements Total length: 1,12 – 1,27 m (3.7‘ – 4.2‘) Number of young: 1 Tail: 25 cm (9.8”) Birth weight: 3,8 kg (8.4 lb) Shoulder Height: 75 cm (2.5‘) Sexual maturity: Male 1 year but mate at 18 – 24 months; Females can conceive at 6 months Weight: 26 – 41 kg (57 – 90 lb) (males slightly larger and heavier than females.) Longevity: One captive 19 years Springbok main Photo: Willem Vorster (African Bushman Safaris) Reintroduced widely Description The only gazelle species occurring in southern Africa. Upperparts, neck and outer leg surfaces are fawn-brown, underparts white and on sides a dark red-brown horizontal stripe separates them. The face is mainly white with light brown markings. There is a large white, long-haired, patch that runs from rump to mid-back that is usually covered with brown hair. When alarmed the “pouch” is opened and the white hairs stand erect. This is further accentuated by the animal giving stiff-legged jumps, with arched back, called pronking or stotting. Both sexes carry lyrate-shaped and heavily ringed horns, but those of ram heavier. White, black and copper coloured springbok are specifically bred for the sport-hunting “novelty” market. Generally “Karoo” and “Kalahari” races recognised, but much interbreeding has taken place. “Kalahari” larger and longer-horned. Distribution A near southern African endemic, extending very marginally into Angola. Restricted to South Africa, Namibia and Botswana and has been widely reintroduced and introduced through the first two countries. Huntable in the three Right front, 55 mm (2.2”) Right back, 54 mm (2.1”) main range states, as well as introduced populations in Texas (USA). Conservation standing Probably between 500,000 and 800,000 animals, many on game ranches. Habitats Open, arid plains with grass or low scrub and can be independent of water, but will drink. Behaviour Normally lives in small herds, but may gather in the hundreds and even thousands in some areas. In some areas of Namibia and Botswana there are movements related to rainfall and new plant growth. The smaller herds may contain rams and ewes but bachelor herds are common, as are solitary rams. Rams are territorial during the rut and they attempt to hold ewe/young groups within their area. But territories are generally only held for short periods and rams then circulate freely. May be active day and night, but generally lie up during the hottest hours. Shot placement Rifles and Ammunition Suggested Calibre: .224 to .270. Bullet: Expanding bullet. Sights: Medium to high-range variable scope. Hunting Conditions: Expect medium to longer shots in open plains. Food Mixed feeders taking grass, forbs and browse. 211 Springbok Springbok ewe with newborn lamb Adult black springbok ram in veld Springbok ram White springbok 210 Game Animals of the World Springbok may form large herds
