FUN FACTS

1. Sable congregate in herds of 15-20 individuals with matriarchal social structure. Within the group, the more dominant female is the leader. There is only one adult male (called a bull) in each herd. The juvenile males are exiled from the herd at about 3 years old.
2. All the female calves remain. When the herd gets too large, it divides into smaller groups of cows and their young. These groups will form new herds, once again with only one adult bull.
3. The young males, which have been separated from the herd, associate in "bachelor groups" of up to 12 individuals. Among the bachelors, the most dominant will be the first individual to join a new group of females when the position is open. Very seldom, during their fights for supremacy, are they able to inflict bodily harm to the contender.
4. If threatened by a predator, including lions, they will confront it, using their scimitar-shaped horns. Many of these big cats have died during such fights.
5. In Ernest Hemingway's book, The Green Hills of Africa he describes the habits of sable antelope, which he used to hunt.

ECOLOGY AND CONSERVATION

Despite their effectiveness, the sable's horns have contributed to the sharp decline of the animal, being a highly prized hunting trophy. In addition to heavy hunting, numbers have been reduced severely as part of regional Tse-tse fly control programs.

Their grassland habitat is being reduced due to habitat destruction for agricultural development. Antelope are important to their habitats as grazers and browsers. They are also important as prey for carnivores.
