Taurotragus derbianus
giant eland

The Giant Eland's home range extends from Senegal through southern Sudan.

Giant elands are found in sparse forest during the day, where they take shelter from the heat. They search surrounding savannahs and grasslands for food during the morning and evening when it is cooler. Elands are found in mountainous regions up to altitudes of 4500 meters.

Male giant elands tend to be larger than females, weighing between 400 and 1000 kg. Females weigh between 300 and 600 kg. Shoulder height ranges from 130 to 180 cm, and body length ranges from 210 to 345 cm. Their massive, spiraled horns can extend up to 123 cm on males and 66 cm on females. The giant eland has sandy grey pelage with 8 to 12 whitish vertical stripes on its sides. There are black marks on the ears and hocks, and mature males have a black neck with a large dewlap extending from chin to chest.

Giant elands live in herds of about 25 individuals but larger groups are not uncommon. Migratory movements of herds are determined by the pattern of occurrence of wet seasons. Mature males are usually solitary, and male-female contact can last from a few hours to a few weeks. A dominance hierarchy is determined among males in a herd and influences access to mating opportunities with females. Males use their horns in aggressive interactions to determine position in this hierarchy. Females tend to form their own aggregations, along with calves. Once the calves are weaned they join groups of mixed-sex juveniles for about 2 years. They then join unisex aggregations at sexual maturity.

The diet of the giant eland consists of leaves and fruits from trees, grasses, and herbs. Their long horns are sometimes used to break branches high up on trees to get at the leaves.

Giant elands are a source of large quantities of tender meat, quality hides, and milk with higher protein and fat content than milk from dairy cows. These characteristics, along with the docile nature of the giant eland, have made it the target of domestication efforts in Africa and Russia.

Populations of the giant eland have been declining due to excessive hunting, habitat destruction by agricultural expansion, and the spread of rinderpest. Most of the remaining numbers live in the protected park areas of southeastern Senegal.
