The blackbuck is a diurnal antelope (active mainly during the day). Three kinds of groups, typically small, are the female, male and bachelor herds. Males often adopt lekking as a strategy to garner females for mating. Herbivores, blackbuck graze on low grasses, occasionally browsing as well.
The blackbuck inhabits grassy plains and slightly forested areas. Due to their regular need of water, they prefer areas where water is perennially available.
The antelope is native to and found mainly in India, while it is extinct in Bangladesh. Formerly widespread, only small, scattered herds are seen today, largely confined to protected areas. During the 20th century, blackbuck numbers declined sharply due to excessive hunting, deforestation and habitat degradation.
