Yellow-bellied Marmot

Marmota flaviventris


The yellow-bellied marmot is a large, heavy-bodied ground squirrel in the marmot genus. This particular species is mainly yellowish-brown in color, with a bright yellow to yellow-red underside. They also have distinct yellow speckling on both sides of their necks, a white spot in between their eyes, and beige or yellow patches beneath their ears. They have bushy tails and have hoary fur with whitish tips.


Talus slopes near alpine meadow above 13,000 ft.


Went up into the high country today in hopes of seeing some alpine wildlife (Mountain Goats, Bighorn, pika, marmot, etc). Just as we got up above tree-line the weather quickly turned bad. Fog and a snow/rain mixture made for a very uncomfortable time. I took a couple shots of this marmot as he/she was the only wildlife we really saw. I may try my luck again next weekend!

Possibly ulvalactuca77! What elevation were you at? If you were above tree line then it could have been a marmot or a pika. If you were around town or in the foothills it may have been a prairie dog! Marmots are noticeably bigger though!

I wonder if this is what I saw hiking in CO. I thought they were ground hogs but the were loud and territorial to each other but not skittish to people.
