Habitat
Yellow-bellied marmots primarily inhabit mountainous regions in western North America, including the Rocky Mountains and Sierra Nevada, favoring rocky slopes, meadows, and alpine tundra. They prefer areas with abundant vegetation for food and rocks for burrows and protection. These habitats range from 2,000 to 4,000 meters in elevation.
Diet
Yellow-bellied marmots are herbivores that primarily eat grasses, forbs, flowers, and roots, with a preference for nutrient-rich plants in meadows. They forage during the day, especially in the early morning and late afternoon, to avoid predators. Their feeding behavior includes storing fat in summer for hibernation.
Behavior
Yellow-bellied marmots are social animals that live in colonies with a dominant male overseeing the group. They are diurnal, spending mornings and evenings foraging and the rest of the day basking or retreating to burrows. These marmots exhibit territorial behavior by whistling loudly to warn of danger and hibernate for 6-8 months in winter.
Conservation Status
The IUCN status of the yellow-bellied marmot is Least Concern, with a stable population trend. Major threats include habitat fragmentation from development and predation by introduced species.
