Yellow-bellied Marmot Facts

Yellow-bellied Marmots spend their winters and up to 60 percent of their lives hibernating in burrows underground. They emerge from hibernation each spring. They keep their burrows in very rocky terrain; this helps them avoid predators such as wolves, bobcats and foxes. When they detect a predator near by, they whistle loudly to warn others then take off for the safety of the burrow. That whistling is how they got their colloquial name "whistle pig." Look for them when hiking along rocky trails in the western U.S.
