American PikaThe American pika has a small, round body, peppery brown fur, large round ears and no visible tail. It is between six and eight inches long and weighs about six ounces.

The American pika can be found in western North America from central British Columbia in Canada to Oregon, Washington, Idaho, Montana, Wyoming, Colorado, Nevada, California and New Mexico.

American PikaThe American pika lives in rocky mountain areas and boulder-covered hillsides, usually at elevations of between 8,000-13,000 feet, between the timberline and down into subalpine forest. It makes its home in rock piles and slides. Although pikas live in groups, they are territorial and will guard and defend their own area from other pikas.

American PikaThe American pika is a plant eater. It eats a variety of green plants like grasses, sedges, thistles and fireweed. It will eat some food on the spot and it will carry some food away and store in a pile or "haystack." 

American PikaA pika haystack can contain as much as a bushel of plant matter. The pika will often move the pile to protect it from rain or to find a better drying spot. After the vegetation dries, the pika will move it to its den deep in the rocks. The pika is active all year. It will eat food it has stored in the winter. If its supply runs low, it will forage for lichen and cushion plants.

  Life Cycle
American PikaThe pika first mates about one month before the snow starts to melt. Mating season typically runs from late April to early July. The female gives birth to two to four babies in the spring. The babies are weaned in about three to four weeks. The babies will leave their mother after four weeks and are adult size in about three months. The female may then mate again and have a second litter.

American PikaThe American pika is diurnal, or active in the day. It spends most of the day foraging for food; guarding their territory; watching for predators like eagles, hawks, coyotes, bobcats, foxes, and weasels and sunning itself on the rocks.

American PikaThe pika is very vocal animal. It uses both call and song vocalizations. The call is used to warn other pikas of a predator or intruder and it sounds a little like the bleat of a goat. The song is used mostly by the males during mating season, although the females will use the call in the fall.
