Hoary marmot for comparison.

But no real difference between eastern "groundhogs" and our Columbia basin marmots, right?

I'm gonna go ahead and admit I really don't know the answer to that question.

I only saw one "groundhog" in Ohio briefly, not a good enough look for comparison.


edited--certainly they are both in the marmot family and closely related, if not the exact same thing

The eastern groundhog is the species Marmota monax. The yellow-bellied marmot found in the Columbia Basin is Marmota flaviventris (flaviventris means yellow-bellied in Latin). The hoary marmot found in the Cascades is Marmota caligata.
But this may not always have been the case.  An interesting study done on marmot teeth found in the Porcupine Cave of Colorado revealed the range of Marmota monax to have extended into Colorado with Marmota flaviventris replacing them as the current residents. Scroll down to the conclusions if you don't have the time for the entire article.

So what how is our cuddly Central Oregon rock Chuck fit into the genus pool. The only tv ad we enjoy is out by the Geico insurance people. Especially the wood Chuck's chucking wood.

Not quite PNW (CA) but topically relevant.  Better here than the youtube thread.  So cute!
