The name pika is used for any member of the Ochotonidae, a family within the order of lagomorphs, which also includes the Leporidae (rabbits and hares). One genus, Ochotona, is recognised within the family, and it includes 30 species. Pikas are also called rock rabbits or coneys. It is also known as the "whistling hare" due to its high-pitched alarm call when diving into its burrow. The pika may look like a hamster, but is actually a cousin of the rabbit. The name "pika" appears to be derived from the Tungus "piika", or perhaps from the Russian "pikat'", to squeak. In the United States the pronunciation of the name is usually altered from /pika/ to /pɪka/, probably due to the spelling.
Pikas are native to cold climates, mostly in Asia, North America and parts of eastern Europe. Eurasian pikas commonly live in family groups and share duties of gathering food and keeping watch. North American pikas (O. princeps and O. collaris) are asocial.
In the mountains of Eurasia, pikas often share their burrows with snowfinches, which build their nest there.
Pikas show their peak activity before the winter season. Pikas do not hibernate, so they rely on collected hay for warm bedding and food. Pikas gather fresh grasses and lay them in stacks to dry. Once the grasses dry out, the pikas take this hay back to the burrows for storage. It is not uncommon for pikas to steal hay from others; the resulting disputes are usually exploited by neighboring predators like ferrets and large birds.
In a January 2006 article in the Journal of Biogeography, archeologist Donald Grayson warned that human activity and global climate change appeared to be pushing the American pika population to ever-higher elevations, and thus possibly toward extinction. Grayson studied pika habitation over the past 40,000 years in the region between the Sierra Nevada (US) and Rocky Mountains. An earlier Journal of Mammalology article reached a similar conclusion.
The pika has several adaptations that allow it to survive in the cold climate of the tundra.
BODY-The small body size allows the pika to find shelter in the crevices of rocks and boulders.
FUR-The thick fur covers the pika from the top of its head to the soles of its feet. This adaptation provides insulation.
COLOR-The pika changes color or molts from season to season. During summer, the pika is very rich in color. It ranges from shades of red to brown. In winter, the pika is dull in color. The winter colors range from shades of brown to gray. Molting or changing color from season to season provides the pika with camouflage.
The climate of the timberline-alpine tundra is to cold to support the growth of vegetation during the winter months. Since the pika does not hibernate, it must have food to eat during the winter months. The pika will cut and store grass during the summer months and store it in "haypiles." A haypile is simply a stack of cut grass that has been left to dry. The pika will then eat the dried grass during the winter months.

Pika
Ochotona princeps
This stocky, tailless little animal with the Roman nose is about 175 mm long and is found in the mountain regions of western Alberta, British Columbia and the Yukon. Diurnal in its habits, it appears in early morning and disappears into its grass-lined nest, hidden in rock crevices, shortly after sunset.
The pika spends considerable time sunning itself on a favourite lookout rock, against which its ‘salt-and-pepper’ coat is difficult to distinguish.
Remaining active throughout the winter under the snow, the pika subsists on stacks of cured grasses and sedges which it stockpiles during the summer months.
Preyed upon by eagles, hawks, bears and foxes, its most dangerous foe is the ermine, which is capable of following it into its rocky tunnels.

Pica (note the spelling) is a condition where animals eat weird stuff (wood, dirt, etc). It's sometimes caused by a vitamin deficiency.
