The brown hyena is one of Africa's least-studied large carnivores: nocturnal, wide-ranging, and persistently misunderstood. At Okonjima Nature Reserve, long-term research is changing that. Drawing on GPS telemetry, camera traps, and over a decade of field observation, this programme has produced one of the most detailed datasets available for Hyaena brunnea. What it reveals is a species far more ecologically complex, socially structured, and behaviourally flexible than its reputation suggests.
