Female impala. View of a herd of female impala (Aepyceros melampus) in grassland. These antelopes inhabit the plains and forest edges of eastern Africa, gathering in herds of up to 200 individuals. Herds are ruled by a dominant male, and the rest of the herd typically comprises females and offspring. Males without a herd usually form a bachelor herd, and often try to infiltrate a dominant male's harem. Impala are renowned for their leaping when startled or attacked. They can jump more than three metres into the air, and as far as ten metres in length. These jumps are designed to confuse predators. Photographed in the Masai Mara reserve, Kenya.
