Brief report on the status of Kozlov's pika, Ochotona koslowi (Büchner), in the east Kunlun mountains of China.

Koslov's pika, Ochotona koslowi (Büchner), was surveyed in western China. This endangered species is poorly known. We determined that it is a burrowing pika, and lives in social family groups at high densities. It primarily occupies high-elevation cold grassland vegetation. It appears to have a high reproductive rate. More emphasis should be placed on research into this unique species in China.
