The plateau pika (Ochotona curzoniae), 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 140 g when fully 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, Asia pole cat, upland buzzard, and owls. They also provide microhabitats by increasing plant richness and their burrows provides nests for small birds and reptiles.
According to the Chinese biologists who have studied the wildlife of the Hoh Xil (northern part of the Tibetan Plateau), plateau pikas are the favorite food of the area's brown bears. In addition to its role as a prey base, the plateau pika is important for soil health in meadows; the burrowing of the species helps to aerate the soil. The species is currently considered threatened, mostly due to aggressive poisoning campaigns by Chinese populations, predominantly to eliminate competition for food with livestock.
Plateau pikas have mating systems such as monogamous and polygynandrous groups, which contain about three males and 3 to 4 females per family along with their offspring. Females can produce 2 to 5 litters of about 2 to 7 offspring with a three-week interval in between each litter which is why this group of lagomorphs are known to have the fastest growth rates of their order. Their breeding season lasts from April to August and the young do not disperse in the year of birth. Males form hierarchies and females are usually philopatric forming reproductive alliances, helping each other in the care of their offspring, males also contribute in parental care when deterring a predator by emitting an alarm call. Males and females both contribute in protecting their family groups from intruders displaying aggressive behaviors towards others who are not part of their family.
