Yellow-bellied marmots resemble large, stout squirrels. They can grow up to 11 inches in length and weigh up to 11 pounds. Their fur is a brownish-reddish color everywhere except for their bellies which, as their name suggests, are yellow. Yellow-bellied marmots can most often be spotted in high elevation areas near rocks.

Fast Facts:

  • Yellow-bellied marmots hibernate up to eight months a year, leaving only a short four months for them to mate, raise their young, and fatten up for the next winter.

  • Since they are most often seen near rocks, yellow-bellied marmots are often referred to as ‘rock chucks’.

  • When they aren’t busy feeding or grooming, yellow-bellied marmots can often be spotted sunning themselves on top of rocks.

  • Yellow-bellied marmots build extensive underground burrows. Abandoned marmot burrows are often used by other species.
