The blackbuck, known scientifically as Antilope cervicapra, is a medium-sized antelope. It is the only living member of the genus Antilope. This species is native to the Indian subcontinent, specifically India and Nepal.

These animals are vital parts of their ecosystems. They inhabit grassy plains and lightly forested areas. They must stay near perennial water sources to survive. This means they need water that stays available all year long. Because they are herbivores, they spend much of their time eating plants. They graze on low grasses like sedges and fall witchgrass. They also browse on trees such as mesquite, live oak, and acacia.

Blackbucks show prominent sexual dimorphism, which means males and females look very different.

Males have a dark brown to black coat on their upper bodies. This dark color is why they are called "blackbucks." They also have white fur on their bellies, ears, tails, and lower jaws. Their faces feature black stripes that contrast with white fur around the eyes and chin. Males possess long, ringed horns that resemble corkscrews. These horns usually measure about 50 centimeters in length. Females and juveniles are a yellowish-fawn or tan color. Females are lighter than males and may occasionally grow horns as well. In Texas, males may look lighter after a spring moult. However, they often grow darker as the breeding season approaches.

Social life for the blackbuck involves several distinct group types. They form female groups, male groups, and young bachelor herds.

Males often use a strategy called lekking to attract mates. In lekking, a male establishes a specific territory. He defends this area from other males to gain access to females. He marks his territory using scents from his preorbital and interdigital glands. He also uses urine and faeces to mark his space. While other males are kept out, females visit these areas to forage. This allows the male to attempt mating with them. Lekking is a demanding and sometimes violent strategy for dominant males.

There are two recognized subspecies of the blackbuck. The first is A. c. cervicapra, the southeastern blackbuck. This subspecies lives in southern, eastern, and central India. Its males have a narrow white eye ring and a black neck. The second is A. c. rajputanae, the northwestern blackbuck. This subspecies lives in northwestern India. Its males have a grey sheen during the breeding season. They also have a broad white ring around the eyes. The white on their undersides extends further up the body. These physical differences help scientists categorize the different populations.

History shows that the blackbuck has faced many challenges. The Swedish zoologist Carl Linnaeus first described the species in 1758. In the 20th century, blackbuck populations declined sharply. This was caused by excessive hunting, deforestation, and habitat destruction. Today, small and scattered herds are mostly confined to protected areas. In India, hunting them is prohibited under Schedule I of the Wildlife Protection Act of 1972. Interestingly, the blackbuck has significance in Hinduism. Many Indian and Nepali villagers do not harm them.

The blackbuck has been introduced to many other parts of the world. They were brought to Argentina, Australia, and the United States. In Argentina, the population of about 8,600 individuals is surviving well. In Texas, they were introduced in 1932. By 1988, they were the most populous exotic animal in Texas after the chital. However, in places like Queensland and Western Australia, they are considered pests. In Victoria, they are regulated as both pests and livestock. These different roles show how an animal can be viewed differently depending on where it lives.

Scientific studies have revealed fascinating details about blackbuck genetics. Males have 31 to 33 chromosomes, while females have 30 to 32. They have an unusual XY1Y2 sex chromosome system. This is a rare trait also seen in some rodents and the sitatunga. The X chromosome in blackbucks is quite large, making up 14.96% of the haploid chromosomal complement.

Research also shows they are closely related to the Gazella genus. A 2013 study by Eva Verena Bärmann and colleagues confirmed this relationship. This genetic information helps scientists understand how the blackbuck evolved within the Antilopini tribe.
