The black pika or silver pika (Ochotona nigritia) is a species of mammal in the family Ochotonidae. It was thought to be common to the Yunnan Province of China[2] where it was first discovered in 2000, it is only known from four specimens. The validity of the species has been questioned,[3] with some studies suggesting that the known specimens represent melanistic individuals of Forrest's pika (Ochotona forresti).[4]

Subsequently, in 2011, a WWF-India team on an expedition to West Kameng, India reported sighting two black pikas at an altitude of 13,000 ft in the Thembang Bapu community-conserved forest area.[5]

It is rarely found, one of the six pika species endemic to central China, with no true population studies.[6][a]

The other five species are Thomas's pika (Ochotona thomasi),Forrest's pika (Ochotona forresti), the Gaoligong pika (Ochotona gaoligongensis), the Tsing-ling pika (Ochotona huangensis), and the Muli pika (Ochotona muliensis).[6]
