Shoulder height - 117 - 140cm (male) 117 - 140cm (female)
Adult weight -235 kg (male) 220 kg(female)
Age at sexual maturity - 5 years (male) 2.5 years (female)
Lifespan: 20 years
Habitat: Light woodland
Diet -A grazer/browser, eats grasses supplemented by foliage and herbs, especially kinds growing on woodland termite mound
Preditors- Because it is big and inhabits regions with comparatively little wildlife, sables usually have relatively few predators. Lucky for them, as laggard young are vulnerable to spotted hyenas and leopards.
Sounds - Birdlike wistles
Mating season - All year round
Gestation period -8 - 9 months
No of young - 2 - 4


Rivals the greater kudu as most-handsome antelope.. Compact, powerful build, thick neck enhanced by upstanding mane, and sturdy legs. Resemblance of females and males holds up to 3 years or until males become darker and develop bigger horns.

Head: long muzzle with wide gape.

Horns: massive and more curved in males, 32 to 65 in (80-165 cm); 24-40 in (60-100 cm) in females.

Coat: short and glossy. Color: bulls black, females and young sorrel to chestnut (except southern race, in which females also turn brown-black); white "eyebrows" and muzzle divided by cheek stripe; white belly and rump patch. Calves under 2 months light tan with faint markings.

Preferred habitat combines savanna woodland and grassland; trees (fire-resistant, broad-leafed, deciduous) widely spaced with understory of sparse grasses utilized in rainy season. Drainage-line and floodplain grasslands that produce new growth after the annual fires keep sable in open during dry season. Goes to water at least every other day and regularly visits salt licks (also chews bones to make up for mineral-deficient soils).

Traveling on average approximately 1/2mi (1.2 km) a day, sables are especially sedentary on dry-season pastures, when herds may spend weeks on the same field, leaving only to go to water or seek shade during hottest hours. But periodically herds move several miles and resettle on another pasture. Sables also regularly graze until dark, then move off before settling down to chew the cud, a tactic that makes it harder for predators to spot a herd's resting site and sneak up after dark.

Herds of 15 to 25 females and young are typical but often represent only part of the residents (typically 30-75 sables in good habitat) sharing a common, exclusive home range of 4 to 10 mi2 (10-25 km2), incorporating territories of 1.5 to 3.5 mi2 (3.9-9 km2) of up to 5 bulls or more. Some herds or subpopulations have separate dry- and wet-season ranges miles apart. The general pattern in all populations is dispersal in small groups during the rains and early dry season, and dry-season concentration in large herds on available green pastures. A female rank hierarchy based on seniority is continually reinforced by aggressive and submissive interactions. Males are subordinate to adult females until they grow bigger; by then obvious male secondary characters make them persona non grata to territorial bulls. Evicted from female society between 3 and 4 years, males live in bachelor herds until mature at 5, or stay alone, if no group is available, keeping out of the way of territorial bulls. Territorial bulls often stay alone, even when a female herd is in residence, patrolling and scent-marking or just hanging out in some shady grove. Though conspicuous in a herd of brown females and young, lone bulls standing still in a clump of trees are easily overlooked.

An annual calving season at the end of the rains. Season extends for several months and a few calves are born as much as 6 months out of phase, Gestation 8 to 9 months. Females conceive at 2.5 years; males adolescent by then but unable to compete for territories and mating opportunities until mature. Even in territorial class, certain prime bulls dominate their neighbors.

Mothers stay secluded for first week or so of the calf's 3-week hiding stage. Cows with calves concealed in the same locale associate in maternal herds. Calves join cohesive peer group as they outgrow the concealment stage and seek mothers only to nurse; after weaning (6-8 months), calves have still less contact. Maternal-offspring bond is so weak that even small calves may be in different sections of a divided herd for days.

Expect to see and hear Usual context and meaning Territorial Advertising Scrape marks made by pawing identify dling deposits made by territorial sable.
