Yellow Bellied Marmot
Yellow Bellied Marmot (Marmota flaviventris) - Rocky Mountain National Park, CO
Marmots make their homes under rocks to protect themselves from predators. They are often seen standing on their hind legs keeping an eye out for any danger that may be lurking nearby. When a predator is spotted it whistles to warn other marmots of the danger. Because of this marmots have gained the nickname "whistle pig"
