The impala is a medium-sized antelope found in eastern and southern Africa. Active mainly during the day, the impala may be gregarious or territorial depending upon the climate and geography. Three distinct social groups can be observed: the territorial males, bachelor herds and female herds. The impala occurs in woodlands and sometimes on the interface (ecotone) between woodlands and savannahs; it inhabits places close to water. While the black-faced impala is confined to southwestern Angola and Kaokoland in northwestern Namibia, the common impala is widespread across its range and has been reintroduced in Gabon and southern Africa.
