The bluebuck moved around in small- to medium-sized herds of up to 20 individuals (4). The herds consisted of females and their young, led by a single dominant male that excluded other males from the herd (3) (7). On encountering another dominant male an extremely violent brawl would ensue, with a clash of the enormous horns and intense head-butting (3).
The bluebuck was a specialised grazer that grazed mainly on perennial tuft grasses (7) (9), such as red grass or spear grass. Mating could occur all year round, although there was a peak in summer (3). The female gave birth to a single calf, weighing around 12 kilograms, after a gestation period of nine months. Many calves were attacked by lions, leopards, spotted hyenas and African wild dogs and killed within months of birth. Upon reaching maturity, males were excluded from the herd by the dominant male bull (7), and were forced to live in bachelor herds with other evicted males until becoming a dominant male in another herd. Life expectancy in the wild was around 18 years (3).
