The hoary marmot is a species of marmot that has a body length ranging from 62 to 82 cm and bodyweight that is around 3.75 kg, but in winter, a fully developed adult can reach a weight of up to 7 kg.
Inhabiting the mountains of Northwest America, these marmots live on slopes with grasses, and around rocky areas as protection from their predators.
They are often nicknamed the whistler due to the high-pitched alarm calls used to warn other members of the colony of a possible danger. This species of squirrel is larger than most, with short and heavy limbs.
