If shade is available, females remain solitary; otherwise, they, along with their offspring, congregate to form herds of ten animals. Female home ranges span over , while the larger territories of males cover . These home ranges keep overlapping. As the daughters grow up, they distance themselves from their mothers' home ranges. Territorial males are much tolerant; they may even associate with up to 19 bachelor males in the absence of females. As many as five females may be found in a male's territory. Territorial bulls drive out their sons when they start developing horns (when they are about a year-and-a-half old). These young males form groups of two to three individuals on the borders of territories, till they themselves mature in their fourth year. Large aggregations are observed during the dry season, when hundreds of bohor reedbuck assemble near a river.
