Life History:

Pikas breed in March or April and have a litter of three or four young after a gestation period of about 30 days. Some females have a second litter. Maximum life span is three to seven years.


Distribution and Habitat:


The American pika is a small mammal that inhabits fields fringed by suitable vegetation in alpine and subalpine mountain areas extending south from central British Columbia and Alberta into the Rocky Mountains of New Mexico and the Sierra Nevada Mountains of California. The historical range of the species includes California, Nevada, Oregon, Washington, Idaho, Montana, Wyoming, Colorado, Utah, and New Mexico.

A key characteristic of the American pika is its temperature sensitivity; death can occur after brief exposures to ambient temperatures greater than 77.9 °F. Therefore, the range of the species progressively increases with elevation in the southern extents of its distribution. In Canada, populations occur from sea level to 9,842 feet, but in New Mexico, Nevada, and southern California, populations rarely exist below 8,202 feet.




Predators, which includes: eagles, hawks, coyotes, bobcats, foxes, and weasels. As they live in the high and cooler mountain regions, they are very sensitive to high temperatures, studies suggest that species populations are declining due to various factors, most notably global warming
