Eland


Eland


Physical Characteristics

The cowlike eland is the world's largest antelope and is the animal most often depicted in the early rock art of East Africa. Even today, it still holds an important place in the mythology of some southern African tribes.

The cow-like eland is the world's largest and slowest antelope. However, it has the endurance to maintain a trot indefinitely and can jump an 8 foot fence from a standstill. Both males and females have horns that spiral tightly, though female horns tend to be longer and thinner. A tuft of black hair grows out of the male eland's prominent dewlap, the loose fold of skin that hangs down from the neck. Adult males also have a mat of hair on the forehead that grows longer and denser as the animal ages. Usually fawn or tawny-colored, elands turn gray or bluish-gray as they get older; the oldest animals become almost black.

Habitat

Elands are found in grassland, mountain, subdesert, acacia savanna and miombo woodland areas. They distance themselves from deserts, forests and swamps.

Behavior

The social organization of the eland is somewhat different from that of other antelopes. The older the male, the more solitary its tendencies, while younger animals may form small groups. Males are also more sedentary than females, who may travel widely, especially during the dry season. Females and young are found in loosely cohesive groups. Calves spend a lot of time grooming and licking each other, developing bonds even stronger than those of a calf with its mother. The attraction calves exhibit towards each other probably developed as a defense tactic, as herds with calves are consistently larger than those without.

Eland young are born year round. Females with young calves come together in nursery groups, where the young spend a lot of time grooming and licking each other and developing bonds even stronger than those of a calf with its mother. After the young are weaned at about 3 months, the mothers rejoin the female herds and the calves remain together in the nursery group. With year-round births, some adult females are always present in a nursery group and they defend all juveniles present, not just their own. Juveniles usually remain in the nursery groups until they are almost 2 years old, when they begin to wander off and join other loose groupings of their own sex.

Diet

Although the eland is often considered a plains-dwelling animal, they browse more than graze, feeding in areas where shrubs and bushes provide the leaves they prefer and using their horns to bring twigs and branches into reach. They also consume certain fruits, large bulbs and tuberous roots.

Predators and Threats

Due to the eland’s size and docility, as well as its rich milk, tasty meat and useful hide, it is becoming an increasingly popular ranch animal. However, its need for a vast range to find sufficient browsing and its low density in number create game management problems and this new idea may not be viable in the long term.

Did You Know?

* The eland's size and docility as well as its rich milk, tasty meat and useful skin have encouraged research on its use in game ranching. Elands have been semidomesticated in some areas.
* Although eland groups are not very stable and animals move from one to another, a dominance hierarchy that is usually based on size, strength and age does exist.
