Highly variable, however this species typically happens in open habitats starting from guinea savanna, moist savannas, woodland mosaics, flood plains, to montane and coastal grasslands. Densities in optimum habitat recorded at up to 91 per mi 2 (35 per km2), however extra sometimes 1–10 per mi 2 (0.5–four per km2) in appropriate habitats.
Behaviorally versatile, this antelope is tailored to a spread of environmental circumstances and conduct is linked to native circumstances.
