Boselaphini

Boselaphini is a tribe of antelopes found in India and Nepal. The tribe currently contains only two species, the nilgai and the four-horned antelope. Both species are relatively large antelopes with stout bodies. The nilgai, Boselaphus tragocamelus, is the largest Asian antelope. Males are typically bluish-grey, while females and young are tawny. They are characterized by two horns, while the four-horned antelope, Tetracerus quadricornis, has two pairs of horns, for a total of four. This latter species is smaller and more reclusive than the nilgai.

The nilgai inhabits a variety of habitats, including forests, grasslands, and scrublands. They are primarily grazers, feeding on grasses, leaves, and fruits. Nilgai are often found in small herds. The four-horned antelope, on the other hand, prefers drier, more open habitats with some cover. Their diet consists mainly of grasses, leaves, and twigs. They are typically solitary or found in pairs.

The distribution of Boselaphini is restricted to the Indian subcontinent. The nilgai is widespread throughout India and extends into Nepal. The four-horned antelope has a more limited range, found in fragmented populations across India and into the Terai region of Nepal.

Both species are considered least concern by the IUCN, though some populations may face local threats from habitat loss and hunting. Conservation efforts are in place to protect these unique antelope species and their habitats.
