A gregarious species, the mammals typically lives in herds of around 5 to 50 individuals, though herds of several hundred have been reported (2) (4). These herds may contain both males and females, or may be comprised entirely of males, or made up of females and their offspring (4). The blackbuck is typically active throughout the day during the cooler months, but mainly in the morning and late afternoon when temperatures are high (2). It is primarily a grazer, feeding mainly on grasses, although other plants are taken depending on seasonal availability (2) (5) (7).
While mating may occur throughout they year, the mammals has reproductive peaks from March to April, and August to October (2) (4). During this time, the males occupy territories which can vary both in size and their proximity to the neighbouring territory. In some populations, males defend large, scattered territories, while in others males gather into small, clustered territories and appear to use a lek mating system (2) (4). It is thought that female group size may determine the mating strategy employed by the male blackbuck (4).
The female blackbuck gives birth to a single young after a gestation period of six months (2). In most antelope species, the young then remains hidden for the first few weeks, with the female returning periodically to suckle it (8).
The mammals is predated upon by a number of species, including wolves and leopards, and relies mainly on its speed in order to escape (7) (9). When a potential predator is sighted, the blackbuck can leap extraordinarily high into the air, before performing a number of smaller leaps and then galloping away at speeds of up to 80 kilometres per hour (2). In the wild, the blackbuck has been known to live up to 18 years of age, with individuals in captivity surviving for even longer (2).
