Groundhog vs Woodchuck

A groundhog and a woodchuck are the same animal, a marmot in the squirrel family. It is a medium-sized rodent about 20 to 26 inches long including a 6-inch tail, weighing about 5 to 10 pounds, with yellowish-brown to blackish-brown fur and white front teeth. The two names are regional and traditional, not two species.

The word woodchuck has nothing to do with chucking wood. It is an English version of an Algonquian word meaning digger. Whistle pig, another nickname, comes from the alarm whistle the animal makes, and an old name, thick woods badger, helped separate it from the badger. Wildlife agencies such as Pennsylvania and Vermont list it under the name woodchuck.

When you are looking at which

Groundhog

• The animal is called a groundhog in your family or region.
• You want the name that describes where it lives, on the ground.

Woodchuck

How this works

Unlike most pages here, this quiz is not about telling two animals apart, because they are one. It asks about context, such as holiday versus tongue twister or agency page, and shows which name most often fits that setting.

Every answer ends with the same fact, so no result is wrong, and the short quiz is just for fun: groundhog and woodchuck are the same species, Marmota monax. If your answers are mixed, the result will say the names are interchangeable, which is the accurate answer.
