Pikas

The pika is a small mammal, with short limbs, rounded ears, and short tail. It is also known as the "whistling hare" due to its high-pitched alarm call when diving into its burrow. The name "pika" appears to be derived from the Tungus piika.

Habitat

Pikas are native to cold climates, mostly in Asia, North America and parts of eastern Europe. Most species live on rocky mountain sides, where there are numerous crevices to shelter in, although some also construct crude burrows. A few burrowing species are instead native to open steppe land. In the mountains of Eurasia, pikas often share their burrows with snowfinches, which build their nests there.

Pikas are diurnal or crepuscular, with higher altitude species generally being more active during the daytime. They 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.
Eurasian pikas commonly live in family groups and share duties of gathering food and keeping watch. At least some species are territorial. North American pikas (O. princeps and O. collaris) are asocial, leading solitary lives outside the breeding season.
