FUN FACTS

1. Roans congregate in herds of up to 20 individuals with a very characteristic 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, they are able to inflict bodily harm to the contender.
4. Roan antelope are brave animals. 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. Roan vocalization is an unusual whistle. Three basic sounds having been recorded: a high-pitched squeal signifying anger, an equine snort for alarm, and a low hissing sound when wounded.

ECOLOGY AND CONSERVATION

Related to the Blaaubok, an extinct southern African antelope, the future looks good for the roan, despite declining numbers. 

These antelope have been hunted for their meat and skin. Despite their effectiveness, the roan'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.
