|Scientific Name:||Ochotona macrotis|
|Species Authority:||(Günther, 1875)|
|Taxonomic Notes:||There are currently five recognized subspecies: Ochotona macrotis auritus, O. m. chinensis, O. m. macrotis, O. m. sacana, and O. m. wollastoni (Hoffmann and Smith 2005). One molecular study concluded that O. macrotis is a sister species of O. roylei (Yu et al. 2000).|
|Red List Category & Criteria:||Least Concern ver 3.1|
|Assessor(s):||Smith, A.T. & Johnston, C.H.|
|Reviewer(s):||Boyer, A.F. & Johnston, C.H. (Lagomorph Red List Authority)|
This is a widespread species. Although there are no data regarding the current population status, it is speculated that Ochotona macrotis is common (Gurung and Singh 1996).
|Previously published Red List assessments:||
|Range Description:||The geographic distribution of Ochotona macrotis includes southeastern Kazakhstan, eastern Kyrgyzstan and Tajikistan, northeastern Pakistan and Afghanistan, northern India, Nepal, and Bhutan (Smith et al. 1990), and in the mountainous regions of several provinces of China (Xizang, Sichuan, Xinjiang, Yunnan, Qinghai, and Gansu) (Smith and Xie 2008). This species occupies elevations ranging from 2,300 m (Gurung and Singh 1996) to 6,400 m (Smith and Xie 2008). O. macrotis will occupy higher elevations when sympatric with O. roylei (Smith et al. 1990).|

|Population:||There are no data regarding the current population status of Ochotona macrotis. It is thought to be common (Gurung and Singh 1996). Population sizes typically do not fluctuate over time, but total density can range from six to eighteen individuals at different localities (Smith et al. 1990).|
|Current Population Trend:||Unknown|
|Habitat and Ecology:||Ochotona macrotis is a rock-dwelling species of pika (Smith et al. 1990). It occurs in high alpine deserts and spruce forest expanses within its geographic distribution (Smith et al. 1990). O. macrotis is characterized as a generalized herbivore (Smith and Xie 2008). It typically feeds on grasses, leaves, twigs, mosses, and lichens (Gurung and Singh 1996). Not all populations of this species construct haypiles for the winter (Ognev 1966). O. macrotis is primarily a diurnal species (Gurung and Singh 1996). The total length of this species is 15.0-20.4 cm (Smith and Xie 2008). Longevity of this species of pika is three years of age (Bernstein and Klevezal 1965). Litter size and number of litters in a year is variable according to location, but O. macrotis usually has two litters per year, with two to three young per litter (Smith et al. 1990). Yearlings of a population are able to breed (Smith et al. 1990). The reproductive periodicity of O. macrotis is April to mid-August (Sokolov et al. 1994). Gestation is approximately 30 days (Sokolov et al. 1994).|
|Major Threat(s):||There are no known threats for Ochotona macrotis (Smith et al. 1990).|
|Conservation Actions:||In India, this species occurs in Hemis National Park and Kanji Wildlife Sanctuary and may be present in Changthang Wildlife Sanctuary (Mallon 1991). In China, this species occurs in Tuomuerfeng and Zhumulangmafeng Nature Reserves (CSIS 2008). Research to determine the current population status is needed. In China, this species has been regionally Red Listed as Least Concern (Wang and Xie 2004).|
