The Common Eland, also known as the Southern Eland or Eland Antelope, is a savannah and plains antelope found in East and Southern Africa. Common Eland live on the open plains of southern Africa and along the foothills of the great South African plateau. They eat grass, branches and leaves and are diurnal but tend to be inactive during the heat of day.
Herds usually have 30 to 80 individuals, but are known to exceed 400. The Common Eland has an unusual social life, leaving or joining herds as necessary without forming close ties. Females have a tan coat, while males have a darker tan coat with a blueish-grey tinge; there may also be a series of white stripes vertically on the sides of bulls. Males have dense fur on their foreheads and a large dewlap. Both sexes have horns, about 65 cm long and with a steady spiral ridge (resembling that of the bushbuck). The female's horns are wider set and thinner than the male's. They eat branches leaves and berries.
