The nilgai or blue bull (Boselaphus tragocamelus) is the largest Asian antelope and is endemic to India, Nepal and Pakistan. The nilgai is the sole member of the genus Boselaphus and placed in the family Bovidae. A sturdy thin-legged antelope, the nilgai is characterised by a sloping back, a deep neck with a white patch on the throat, a short crest of hair along the neck terminating in a tuft, and white facial spots. A column of pendant coarse hair hangs from the dewlap ridge below the white patch. Sexual dimorphism is prominent – while females and juveniles are orange to tawny, adult males have a bluish-grey coat. Only males possess horns.
