In celebration of Groundhog’s Day, we feel it’s only right to take a moment to celebrate Yosemite’s groundhog, the Yellow-Bellied Marmot. We’ve put together some of our favorite Yellow-Bellied Marmot facts here, be sure to check them out!
Yellow-Bellied Marmot Facts:
- Yellow-Bellied Marmots are also known as “Rock Chucks!”
- Marmots are mammals with grizzled brownish fur, a yellow belly, and a whitish spot between the eyes.
- Marmot’s omnivore diets usually consist of grass, leaves, flowers, fruit, grasshoppers, and bird eggs.
- Marmots usually weigh between 5 and 11 pounds when fully grown.
- Marmot weight fluctuates through the year, with a huge gain in weight before hibernation.
- Marmots inhabit Yosemite’s high country, usually at elevations above 6,500 feet.
- Marmots often live in small colonies, which means if you see one, stop hiking, remain quiet, and wait to see some more!
- Marmot colonies consist of groups of about 10 to 20 Yosemite groundhogs.
- Marmots have what is called “harm-polygynous” which means the male defends and provides for 1-4 mates at the same time.
- Marmots choose to dig burrows under rocks because predators are less likely to see their burrow.
- Marmots warn others of predators nearby by emitting a shrill whistle, which is how they get the nickname “Whistle Pig.”
- Marmots hibernate in the winter, remaining in their burrows from September to May.
