Conservation Status: Least Concern.

Collared Pikas are common in the mountains of central and southern Alaska, particularly above timberline. They are very vocal animals, calling loudly to one another with short, sharp sounds that may be alarm calls or have a role in courtship. Their hearing and vision are excellent, and they climb with agility. They require a rocky area for cover, and a nearby meadow or other patch of vegetation where they can forage. Although winter conditions are harsh, Collared Pikas do not hibernate. In the summer they accumulate piles of cut grass and other vegetation to get them through winter, and yet they must still do some winter foraging: their haypiles are insufficient to meet all their nutritional needs. Related to rabbits and hares, pikas resemble those lagomorphs, but they have much shorter legs and short, rounded ears.
