Collared pika are one of only two species of pika in North America and are currently found in Alaska and Canada. The other species, the American pika, lives farther south in North America and has become a canary in the coal mine for climate change because it is very susceptible to warming and has been lost from many areas where it once occurred. But for collared pika, we don’t know whether temperature changes are a threat.

Collared pika live in talus outcrops, which are rocky outcrops or boulder fields with individual rocks between shoebox- to truck-sized. Unlike ground squirrels and marmots, they do not hibernate.

In order to survive all winter long, they spend the summer gathering plants, drying them in the sun, and then storing them as “hay piles” amongst and under the rocks. They even store toxic plants, like the Alpine avens, to use as a preservative, and wait to eat it until the toxic chemicals break down and it’s safe to eat.

Collared pika are related to rabbits and hares, but they have short, round ears. Their name comes from the light circle of fur around their neck that forms a “collar”.

They are about the size of a small rat or guinea pig and live in colonies. Their alarm call sounds like the high-pitched squeak of a dog toy- so if you hear a toy-like squeak, be on the lookout for collared pika.

Because they are highly sensitive to temperature changes and are restricted to talus outcrops, collared pika are likely to be threatened by climate change. Collared pika are listed as a species of greatest conservation need by Alaska’s State Wildlife Action Plan and a species of special concern under the Species at Risk Act in Canada.

Current IUCN Listing: Least Concern

The recommended targets are real, but the largest health gain is between doing nothing and doing a little. That is the part worth knowing if you are starting from nothing.

Sleep is not one state but a cycle through several, each doing different work. Most sleep disorders are a failure to complete that cycle rather than a shortage of hours.
