The plateau pika, also known as the black-lipped pika, is a species of mammal in the pika family, Ochotonidae. It is a small diurnal and non-hibernating mammal weighing about 140g
when full grown. The animals are reddish tan on the top-side with more
of a whitish yellow on their under-belly. They prefer to live in elevations of 3,100 to 5,000 m, mostly in the Tibetan Plateau, which is where the common name originates from. The species is found in China, Pakistan, India, and Nepal in high alpine deserts, steppe and meadows, as well as tropical and subtropical montane forests. Plateau pikas are considered to be a keystone species as they play a role in recycling nutrients in soil, providing food to predators such as; foxes, weasels, falcons and owls. They also provide microhabitats by increasing plant richness and their burrows provides nests for small birds and reptiles.
