Oh, that's right, Woodchuckers. It's fruit hog day. Get out and check that hog out there.

February 2nd, the day each year when we look towards an oversized rodents to find out how much more winter

will endure.

In honor of the occasion, here's seven things you might not have known about the Groundhog.

Number one, the Groundhog's scientific name is Marmoda Monax, making it one of 14 types of marmit that can be found in the Northern Hemisphere.

Oh, nice marmit.

Marmit's are members of the Syriday family, which makes the Groundhog just a really big ground

squirrel. Number two, as just noted, Groundhogs are a type of marmit, so you could accurately

say, hey, that marmot just saw its shadow. You could also refer to them as woodchucks, whistle

pigs, or land beavers depending on where you're from. The name whistle pig comes from the high-pitched

whistle that groundhogs admit to warn the rest of a colony about danger.

And contrary to what you might think, the name Woodchuck has nothing to do with wood.

It's derived from an Algonquian name for the animal, Wuchak. A big enough

groundhog could nevertheless chuck some wood. Number three, male and female groundhogs tend to occupy the same territories year after year.

Males also tend to avoid other males, but they have much larger home ranges.

Their territories can overlap with as many as three females territories.
