The Black pika or Silver pika (Ochotona nigritia), is a new species of pika in the Ochotonidae family. It was thought to be endemic to Yunan Province of China where it was first discovered in 2000, it is only known from four specimens. The validity of the species has been questioned, with some studies suggesting that the known specimens represent melanistic individuals of forrest's pika. Subsequently, in 2011, a WWF-India team on an expedition to West Kameng, India reported sighting 2 black pikas at an altitude of 13,000 ft in the Thembang Bapu community-conserved forest area.
