Arctic Ground Squirrel

Image Description

Arctic Ground Squirrel It is one of the few Arctic animals that hibernate. In the summer it forages for tundra plants, seeds, and fruit to increase body fat for its winter hibernation. By late summer the male arctic ground squirrel begins to store food in its burrow so that in the spring it will have edible food until the new vegetation has grown. The burrows are lined with lichens, leaves, and muskox hair. During hibernation, its brain drops to just above freezing, its core body temperature reaches temperatures down to -2.9°C and its heart rate drops to ~1BPM.
