PIKA (Ochotona princeps saxatilis)

A small, tailless member of the rabbit family, guinea-pig like in

form, with short, round ears and a varying colored coat, ranging from

buffy to brown. Total length 7 inches. Height at shoulder 3 inches.

The little, abrupt-moving pika is found abundantly among the rock slides

and slopes from timberline to the highest alpine peaks. Its high, quick

bleat or shrill squeak, ventriloquistic in character, may be heard at

any of the large rock piles in the alpine zone. Having a pronounced

preference for cooler climate, it is but rarely found in the

lower-valley montane zone. Wonderfully camouflaged to blend in with the

rocks where it lives, it always crouches on all fours, never "sitting

up" as do the similar sized ground squirrels. The pika spends his summer

industriously gathering grasses and flowers and "curing" them on the

sun-baked rocks to form his winter supply of food or "haypile." He does

not hibernate, but lives actively throughout the winter, snug and secure

from winter storms among the rock piles.
