![]() ![]() While adapted to face harsh cold conditions, pikas are very vulnerable to increases in temperature: pikas can perish in as few as six hours of exposure to moderate temperatures of 75-77 degrees. Intergovernmental Panel on Climate Change. With continued climate change, temperatures in the western United States could increase by 5.4 degrees Fahrenheit by 2050, and up to 10 degrees Fahrenheit by 2100, according to the U.N. ![]() Pikas' tremendous ability to keep their bodies warm in such fierce conditions now poses a threat to the species. At this point, the babies leave the mother, though they will not be adult size for another two months, and the mother may mate again. Pikas give birth to two to four babies, and raise them for about four weeks. During this time, males will use their call to attract females. Typically, pikas mate about a month before the first snow melt, somewhere between April and July. Pikas are diurnal, active during the day, and forage year-round.

Pikas' thick, brown fur and round bodies help them conserve heat efficiently on treeless, wind-swept slopes. In Oregon, American pikas are celebrated residents of Crater Lake National Park, as well as other mountainous areas of central and eastern Oregon.Īmerican pikas possess adaptations that allow them to exist in such cold places. Pikas are only found in the western part of North America, from British Columbia, Canada to New Mexico, United States. Pikas are an important source of food for many fur-bearing mammals.Commonly referred to as the "rock rabbit," American pikas are small mammals that inhabit rocky, cold alpine and subalpine areas, typically at elevations of 8,000 to 13,000 feet. Breeding generally occurs twice, in spring and summer 2-6 offspring are born per litter. Within a colony, individuals tend to occupy exclusive home ranges, but during breeding season, male and female ranges overlap. ![]() Pikas are diurnal, and both Canadian species are colonial.
