Pikas have exceptionally good hearing, and very acute eyesight, and when gathering or sunning, they will emit a warning if a predator is seen. This warning is in the form of a high pitched whistle, which travels far, and is detected by other pika’s excellent hearing. They live mostly in very rocky mountainsides, and use the existing layout to build shelters, but many times if there is no alternative they will dig a burrow to use.
The Alpine Pika belongs to the subgenus of Pika and the genus of Ochotona, which is in the family Ochotonidae, and the order of Lagomorpha. Lagomorpha contains within it three known families, with Ochotonidae being the Pikas, Leporidae being rabbits and hares, and one other extinct family of large pikas - which had only one modern survivor that was hunted to extinction in the 1700s. The Alpine Pika usually has a litter of young between 25 to 30 days after pregnancy with five or less young at a time. They are very sensitive to temperature change, and can tolerate cold better than heat - and may be a prime indicator of global warming as few will survive longer than an hour in temperatures above 75 degrees Fahrenheit (23 degrees Celsius).
The behavior involving the foraging and gathering of grasses is interesting, in that the Alpine Pika seems to plan exactly what it needs and how to build a sufficiently warm burrow. When they gather fresh material, they leave it outside to dry out - and when sufficiently dry will move it in to their burrow to create the bedding and food supply for winter, building up a significant supply as pikas are not a hibernating species. They continue to do this until there is no more left, or the temperatures prohibit it in a sudden extreme cold snap. When a Pika leaves its material out to dry, occasionally another will be opportunistic and take advantage of the situation - stealing the dried or drying grass for itself. Then ensuring fight may attract a predator.
Some interesting facts about Alpine Pikas:
- Some Alpine Pikas will share their burrows with snow finches (actually a species of sparrow), who will help build it during the summer and fall.
- In general the pika is sometimes known as the whistling hare, because of its high pitched whistle it uses during warnings about predators and invaders.

The Alpine pika is listed as Least Concern (LR/lc), lowest risk. Does not qualify for a more at risk category. Widespread and abundant taxa are included in this category, on the IUCN Red List of Threatened Species
