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]
The northern pika (Ochotona hyperborea) is a species of pika found across mountainous regions of northern Asia, from the Ural Mountains to northern Japan and south through Mongolia, Manchuria and northern Korea. An adult northern pika has a body length of 12.5–18.5 centimeters (4.9–7.3 in), and a tail of 0.5–1.2 centimeters (0.20–0.47 in).
