Marmots are large ground squirrels in the Genus Marmota. They are the heaviest members of the squirrel family. They are active during the summer, but hibernate during the winter. Groups of marmots are called colonies. The burrow system of these colonies have several entrances and exits, providing for safe access when predators approach.
Marmots are herbivores, eating nuts, leaves, seeds, flowers, grass, and grains, and can live from 13 to 15 years in the wild. A marmot will spend a significant amount of time sunning itself on rocks to get warm. When disturbed it will make a whistling sound to alert others around them of a predator in the area and are sometimes called a “whistle pigs”.
