Marmot

They say that marmots are really just large ground squirrels and are found in the Rocky Mountains, Black Hills, Cascades, and Sierra Nevada in North America. Marmots typically live in burrows (often within rockpiles, particularly in the case of the Yellow-bellied marmot), which this one is, and they hibernate there through the winter. Most marmots are highly social, and use loud whistles to communicate with one another, especially when alarmed.
