The ground squirrel is a common sight along the Haines Highway in the Yukon. These medium-sized, ground-dwelling rodents are most often seen along roadsides skirting the boreal forest or tundra. Ground squirrels are known to have distinct calls to warn other squirrels of different types of predators.
Like other squirrels, ground squirrels are seed gatherers who work to store food for their winter hibernation. During the long winter, arctic ground squirrels lower their body temperatures, sometimes below freezing, in a process called supercooling.
