Way of life

The habitat of the Korean pika consists mainly of mixed forest zones or stocks of Korean pine ( Pinus koraiensis ) as well as stony birch forest regions at heights of 700 to 2500 meters; he is a typical inhabitant of rocky regions. The animals are diurnal and feed on green parts of plants and seeds, especially the seeds of the pine trees. Depending on the regional conditions, they collect plant parts from up to ten different grasses and herbs and use them to form balls of around 20 to 1200 grams, which they allow to dry. The animals usually store the bales in crevices in the rock. No information is available on the reproduction of the animals.

Systematics

The Korean Pfeifhase is assigned as an independent species to the Pfeifhasen (genus Ochotona ) and the subgenus Ochotona . The first scientific description of the species comes from Joel Asaph Allen and Roy Chapman Andrews from 1913 as an independent species Ochotona coreana . For a long time it was regarded as a subspecies of the Northern Pigeon Rabbit ( Ochotona hyperborea ), together with the Manchurian Pigeon Rabbit ( Ochotona mantchurica ) based on molecular biological data of the mitochondrial DNA by Andrei Alexandrowitsch Lissowski in his revision of 2013 and in its processing in the Handbook of the Mammals of the World from 2016 considered a separate species.

Apart from the nominate form , no further subspecies are distinguished.

Hazard and protection

The species is currently not assigned to a hazard category by the International Union for Conservation of Nature and Natural Resources (IUCN) due to the insufficient data situation, but classified as “data deficient”. No data are available on the populations of the species.
