The Nilgiri Tahr (varaiaadu)

Spot them during my trip to Eravikulam National Park (Kerala).

The Nilgiri tahr is a stocky goat with short, coarse fur and a bristly mane. Males are larger than females and of darker color when mature. Both sexes have curved horns, reaching up to 40 centimetres (16 in) for males and 30 centimetres (12 in) for females. Adult males weigh 80 to 100 kilograms (180 to 220 lb) and stand about 100 centimetres (39 in) tall at the shoulder. Adult males develop a light grey area on their backs and are thus called "saddlebacks".
