A pika (/ ˈ p aɪ k ə / PY-kə, [3] or / ˈ p iː k ə / PEE-kə) [4] is a small, mountain-dwelling mammal native to Asia and North America. With short limbs, a very round body, an even coat of fur, and no external tail, they resemble their close relative the rabbit, but with short, rounded ears. [5]
The total area of land that a pika uses is known as a home range. About 55% of its home range is territory that the pika defends against intruders. Territory size can vary from 410 to 709 m 2 (4,410 to 7,630 sq ft) and is dependent on configuration, distance to vegetation, and quality of vegetation. [11]

Hoffmann's pika is a member of the kingdom Animalia, the phylum Chordata, the class Mammalia, the order Lagomorpha, and the family Ochotonidae. [3] It shares its family (Ochotonidae) with all other pikas, and the family Ochotonidae represents about a third of the diversity of the order Lagomorpha (which also includes hares and rabbits).
