Nilgai female and calf
The nilgai (Boselaphus tragocamelus), sometimes called nilgau, is an antelope, and is one of the most commonly seen wild animals of central and northern India and eastern Pakistan; it is also present in parts of southern Nepal. The species has become extinct in Bangladesh. The mature males appear ox-like and are also known as blue bulls. The nilgai is the biggest Asian antelope.
The local belief, that nilgai are a cow and hence sacred, has protected it against hunting.
