Alpine Pika

The alpine pika (Ochotona alpina) is a species of small mammal in the pika family, Ochotonidae. The summer pelage of different subspecies varies drastically but, in general, it is dark or cinnamon brown, turning to grey with a yellowish tinge during the winter. The alpine pika is found in western Mongolia, eastern Kazakhstan, and Russia (Tuva, Irkutsk, Altai, and Krasnoyarsk), as well as in China (northern Xinjiang and Heilongjiang), in very cold, mountainous regions. It is a generalist herbivore, and mainly forages on mosses, tree branches, pine nuts, and plant stems. It can emit three series of different vocalizations: a long call, a short call, and an alarm call. It is rated as a species of least concern on the IUCN Red List of Endangered Species. == Taxonomy == German zoologist and botanist Peter Simon Pallas originally described the alpine pika in 1773, in his work Reise durch verschiedene Provinzen des Russischen Reichs. It is a large species in the pika family, Ochotonidae, which consists of small mammals that have short ears, forelimbs very slightly longer than hindlimbs, and no external tail. There are four recognised subspecies: O. a. alpina (Pallas, 1773), O. a. cinereofusca (Schrenk, 1858), O. a. sushkini…
