Some reproductive parameters of collared pika Ochotona rufescens Gray, 1842 were studied during the winter from Ziarat Valley, Baluchistan. Out of 195 animals captured, 105 (53.8%) were males and 90 (46.2%) females. Males were bigger and heavier than non-pregnant females. Mean litter size according to embryo count was 3.6 ± 1.6 (range: 1-7 young/female), and by placental scars 4.48 ± 0.30 (range: 2-6 young/ female). Mean HBL of primiparous females was less than multiparous females. The higher fecundity rate of pika helps to attain its pest status in apple orchards.
