The nilgai is the largest antelope in Asia, a sturdy, thin-legged animal with a sloping back, a deep neck and a white patch on the throat. Males and females look quite different: females and juveniles are orange to tawny, while adult males are bluish-grey. Only males have horns, and a column of coarse hair called the pendant hangs below the throat patch (Wikipedia, general species account).
Major populations live in the Indian and Nepal Terai. The nilgai is diurnal and prefers scrub forest and grassy plains with short bushes and scattered trees. Three kinds of group occur: females with young calves, groups of three to six females and yearlings with calves, and all-male groups of two to 18. Gestation lasts eight to nine months. Nationally Vulnerable (Nepal National Red List 2011).
