Opportunistic hunting behaviour is characterized by the absence of search phase in a prey acquisition sequence (Kok & Nel, 2004). It is especially common among the members of the Canidae (Macdonald & Siller-Zubiri, 2004). Black-backed jackal (Canis mesomelas Schreber) is a common middle-sized canid occurring in two disjunct populations, one in East Africa and the other in southern Africa (Walton & Joly, 2003). It is a generalist feeder, whose diet comprises small-to-medium-sized mammals, reptiles, birds, eggs, invertebrates, plants, carrion and anthropogenic items (Kaunda & Skinner, 2003; Loveridge & Nel, 2004).  Active hunting seems to be more important in the regions with rare or absent specialist predators (Kaunda & Skinner, 2003). Predation on ungulates by jackals is usually limited to fawns (Lawick-Goodall & Lawick-Goodall, 1970; Schaller, 1972; Macdonald, Loveridge & Atkinson, 2004). Present note describes the observation of a successful cooperative hunt of black-backed jackals on adult springbok (Antidorcas marsupialis [Zimmermann]).
