About the size of a large rabbit, a rain drenched Alpine or Arctic Ground Squirrel (Spermophilus parryii) is out foraging. They are omnivorous. These rodents are strictly cold weather creatures, living from Russia to Alaska and Canada. They hibernate in borrows much of the year, there safer from predators like bears or large hawks. They are the only known North American mammal which can sustain a body temperature below freezing by going into "Supercooling", which is being studied extensively at the University of Alaska. When they become too cold, they will shiver for hours, bringing their body temperature up to 98 F degrees, and then cool down again.
