Marmot
High in Colorado’s mountains, listen for the call of the whistlepig. Better known as the yellow-bellied marmot, it’s cousin to the groundhog — evolved to live at high altitudes. In the fall, the rodent’s yellow chested body is plump from a summer feasting on plants, occasional bird eggs and insects, to double its weight to more than 10 pounds, extra reserves to get through eight months of hibernation 15 feet underground, when their body temperature drops to near freezing.
Some scientists say the marmot actually benefits from climate change, with snowmelt earlier in the season making for a hibernation that ends a little sooner, and a longer summer of eating — all the better for a whistlepig building up reserves to snooze through the next underground.
