The Nilgiri Tahr (Nilgiritragus hylocrius), is an ungulate native to the Nilgiri Hills and the southwestern portion of the Western Ghats range in India. It is known locally as the Nilgiri Ibex or simply Ibex. The Nilgiri Tahr is more closely related to sheep than it is to other Tahrs. Its habitat is open mountain grassland within the mountain rain forests eco-region above 6500 feet generally.
The Nilgiri Tahrs are stocky goats with short, coarse fur and a bristly mane. Males are larger than the females, and have a darker color when mature. Both sexes have curved horns, which are larger in the males, reaching up to 15.75 inches for males and 11.75 inches for females. Adult males weigh 175 to 220 pounds and stand nearly 40 inches tall at the shoulder.
