The rat-sized American pika is characterized by rounded ears, no external tail, bare planter pads, and hind feed scarcely longer than the front feet.
The pika requires talus, creviced rock, and other high elevation microhabitats that provide cool microclimates. Adequate forage close to rocky crevices is needed.
In Oregon, the species is limited to suitable habitats in the Cascade Range and the Wallowa, Blue, Strawberry, Steens, Hart, and Warner mountains, and at Newberry Crater in Deschutes County and Grizzly and Cougar peaks in western Lake County.
The American pika is an Oregon Conservation Strategy Species and is limited by its sensitivity to high temperatures and vulnerable to climate change.
