my partner's mom's boyfriend is part of a local search and rescue team, he found this in the woods during one of this runs. I currently have it degreasing 🌿💙
While driving a few days back, I spotted a large rodent. I had to make a turn and the critter scampered very quickly (and safely) off the road, so I didn’t get a great look at it, but based on its size, color, and where I was, I’d venture to say it was one of two creatures: a woodchuck or a beaver. Which got me wondering, how do you tell the difference? For Wildlife Wednesday, here are some facts about woodchucks (Marmota monax) and North American beavers (Castor canadensis):
Part of the confusion with identifying these rodents stems from the woodchuck’s many interchangeable names. Woodchucks are basically big squirrels (sometimes called “marmots”) and are also known as groundhogs and “whistlepigs.”
Woodchucks are active during the day and can often be found on forest borders throughout much of the United States, Canada, and even parts of Alaska. As you can see in the top three pictures above, their short, bushy tails are usually black to dark brown and account for about 25 percent of their total body length.
Woodchucks live in elaborate dens, which are dug in well-drained soils. According to the University of Michigan, “most have summer (located near food sources) and winter (located near protective cover) dens.”
Beavers live in lodges -- built on islands, the banks of ponds, or on the shores of lakes, according to the University of Michigan. The critters are mainly active at night.
Beavers have large skulls and big teeth, which help the animal cut through wood to construct lodges and dam up streams, ensuring enough water flows into its lodge.
Another key beaver feature (bottom two photos above) is the tail. Beaver tails are generally broad and covered with scales. The tails help with swimming (beavers can stay underwater for up to 15 minutes) and are used to store fat and signal danger.

Happy Groundhog Day everyone!🍂 This groundhog skull belongs to a female groundhog that I found in the Spring of 2014 in my favorite park in NJ. One of the big downsides of living in FL. is that there are no groundhogs here, so I haven’t been able to see or work on any others. It’s surprising to think how often I took them for granted before moving South. I used to see them all the time and now I haven’t seen one in over a year and a half!
•Groundhogs are also referred to as woodchucks, marmots, groundpigs, and more!
