Mammals
Yellow-bellied Marmot
Marmota flaviventris
A chunky ground squirrel often seen sitting upright on rocks or near burrow openings. One of the most recognizable mammals visitors may learn about at ABNC.

Field Note
Yellow-bellied Marmots hibernate for up to 8 months — one of the longest hibernations of any mammal in North America. They enter their burrow in September and don't emerge until spring.

Where to Spot It at ABNC
