Impala in Swahili: swala pala (Aepyceros melampus)
Shoulder height: 90 cm; weight: 45 kg. This slender, handsome antelope is superficially similar to some gazelles, but in fact belongs to a separate family. Chestnut in colour, the impala has diagnostic black and white stripes running down its rump and tail, and the male has large lyre-shaped horns. One of the most widespread antelope species in sub-equatorial Africa, the impala is normally seen in large herds in wooded savannah habitats, and it is one of the most common antelope in many Tanzanian reserves. Mixed impala herds typically comprised an alpha male and a vast harem of females and their offspring. Also common, unsurprisingly, are all-male bachelor herds.
