Impala Appearance
How to Identify the Impala and Its Black Variant
The impala, also known as the rooibok, is a medium-sized antelope found across eastern and southern Africa. It is the only living member of the genus Aepyceros. Two subspecies exist: the widespread common impala and the larger, darker black-faced impala that prefers more arid scrubland. The species stands 70–92 cm (28–36 in) at the shoulder and weighs 40–76 kg (88–168 lb).
Its coat is glossy and reddish brown, and males carry slender, lyre-shaped horns measuring 45–92 cm (18–36 in). The black-faced impala differs mainly in colour, as it shows deeper tones and a dark mask across the face. However, both forms share the same refined build and agile movement that define the species.
Life in Their Habitat
Where Impala Live and How They Form Groups
Impala live in woodlands and on the edges between woodland and savannah. They generally stay near water sources, and this requirement guides much of their distribution. The common impala is widespread, while the black-faced impala is limited to southwestern Angola and Kaokoland in northwestern Namibia.
Impala are active mainly during the day. Their behaviour changes with season and landscape; therefore, they may live in groups or hold territories depending on local conditions. Three social groups occur: territorial males, bachelor herds and female herds. Females form the largest groups, while young males join bachelor herds after being pushed out of female units.
Impala show two well-known leaps when threatened. These unpredictable jumps confuse predators, and they also help the herd stay spread out and alert. Additionally, their mixed diet allows them to browse and graze. They feed on grasses, forbs, fruits and acacia pods, which makes them flexible in shifting environments.
Impala Life Cycle
Reproduction and Conservation
An annual rut takes place toward the end of the wet season, typically in May. Males fight for dominance, and the winning male courts receptive females. Gestation lasts six to seven months, after which a single calf is born. The mother hides the newborn immediately, which helps reduce predation in the first days. Calves nurse for four to six months.
Young males leave the female herd once they grow stronger, while young females often remain in the group. Therefore, the herd structure stays stable across generations.
The impala is listed as Least Concern by the IUCN due to its wide and healthy population. However, the black-faced impala is considered vulnerable, with fewer than 1,000 individuals remaining in the wild in 2008. Its limited range makes protection efforts essential for long-term survival.
