Fast facts : Hoary Marmots are the largest North American ground squirrels and live near the tree line on slopes with grasses and forbs to eat and rocky areas for cover. They are oftenly nicknamed "the whistler" for their high-pitched warning issued to alert other members of the colony to possible danger, can weigh up to 13.5 kg (30 lb.), but are usually 5 to 9 kg (11 to 20 lb.), hibernate 8 months a year, are mates for life and a couple generations may live all together in the same burrow. They live in colonies of up to 36 individuals.
