Seven Babies, Yard and 2 Juveniles

AN UNCOMMON AND UP-CLOSE LOOK INTO THE LIVES OF WILD GROUNDHOGS

Observing groundhogs being groundhogs for over fifteen years!

Have a look at our new Woodchuck Food Habits page, and the latest photos and videos.  Explore the news and information page.  And on Amazon check out our 2018 paperback book, The Amazing Groundhogs of Woodchuck Wonderland.

THE PROJECT’S BEGINNINGS

In March 2003, a woodchuck appeared in our yard for the first time. We named her Wilhelmina. We began photographing her. She gave birth to seven babies sometimes called chucklings. Eventually, the mate of Wilhelmina was identified and named Gregory. His teeth were unmistakable!

Our interest grew and it become clear that photographs were insufficient in capturing the activities of these intriguing marmots. So in 2005, we purchased our first camcorder and began videotaping Wilhelmina, her mate Gregory, and their nine babies.

After mother groundhogs bring the chucklings above ground from the nursery, the babies begin to wander away from their natal burrow. We captured the family’s activities eating, sleeping, playing, climbing trees and more by watching, photographing and videotaping them through our home windows. (See Link to YouTube videos) We also observed other mammals, birds, and insects that shared the woodchuck’s territory.


END OF AN ERA AND A NEW BEGINNING
Wilhelmina-May 2011

Woodchucks may live about six years in the wild, though the average is about two-three years. Woodchucks usually breed at two years old. Assuming Wilhelmina was two years old in 2003, we estimate she was about ten years old when last seen in 2011. During her life at Woodchuck Wonderland, she had six litters of babies with two of her three mates.

Trudy-2012

2012 marked a new beginning with a female we named Trudy. She had seven offspring. In 2014 Heidi became our new female resident. In 2015 she and her mate, Luke, were woodchuck parents of seven babies. (see 2015 Photos). In 2016  Heidi had a new mate, Raggedy, and Heidi was mom to eight chucklings! The 2017 season began with five groundhogs, all from 2016, emerging from hibernation. It was an unusual and confusing groundhog season! For more of our groundhog soap opera, check out the 2018 and 2020 Photos and Review pages.

WOODCHUCK NAMES AND IMPORTANCE
Heidi-2014

A woodchuck is also called groundhog, whistle pig, wuchak, and Marmota monax. Monax is an American Indian name meaning “the digger.” Groundhogs improve the soil when digging their home by bringing subsoil to the surface and exposing it to weathering action.

Raggedy-2016

Their burrows are used for hibernating, mating, raising their young and escaping predators. Besides the nest, the den also has a toilet chamber! Groundhogs don’t leave droppings outside their burrow.

Abandoned burrows are used by other animals including red foxes, opossums, rabbits and skunks. While groundhogs hibernate, other animals may use a portion of a groundhog’s burrow.  The groundhog is an important food source for foxes, coyotes, hawks, bobcats, etc.

The groundhog is the only animal we have set aside a special day for on our calendar. Groundhogs are essential to medical researchers studying human liver disease, hepatitis B, and liver cancer. Their hibernating abilities are of significant research interest in the space and medical industries.


PROBLEMS COEXISTING?

The two primary complaints about groundhogs are with their food needs and digging. So what can be done to minimize these problems?

An adult woodchuck may eat 1 to 1½ pounds of food per day though their food intake decreases as hibernation nears. They survive on their body fat while hibernating and may lose up to ½ of their body weight over winter. So in the spring and early summer, gardens planted near their burrows are especially vulnerable to groundhogs. Repellents such as Epsom salts, rags soaked in cider vinegar, a mixture of water, pepper, garlic, and liquid soap, blood meal, human urine, noise, and electronic motion repellents may discourage problem behavior. The use of fencing, including electrified fences, may also be an effective deterrent. We use pepper,  some fencing, and noise as deterrents. Groundhogs prefer hiding places around their burrow holes, so try limiting hiding spots.

If groundhogs dig holes in a problem area, like next to your home foundation, fill in the holes at an appropriate time. We have used a combination of old bricks, larger rocks, dirt, urine and sometimes used kitty litter to successfully fill in burrow holes in problem areas. Other burrow holes are not disturbed. The Humane Society offers suggestions to prevent groundhogs and other animals from making their homes under sheds and decks.

We hope visitors to this website will better understand and appreciate woodchucks. These suggestions may help with problems encountered in coexisting with them.

DISPELLING MYTHS
Sluuuuurp!

Many myths and stories have circulated about woodchucks. For example, in 1883, the legislature of one state passed a bill authorizing a bounty of 10 cents for every woodchuck killed in the state. In part, they stated “The Woodchuck is not only a nuisance, but a bore. It burrows beneath the soil and then chuckles to see a mowing machine, man and all, slump into one of these holes and disappear.”

Numerous publications have reported that the male woodchuck has no part in raising or caring for the young. Our observations tell a different story. It’s also been reported that woodchucks don’t drink but get their liquids from the juices of plants. We’ve documented them drinking from our birdbath, lapping water in puddles and off plant leaves. Our goal is to sort myth from reality and share what we see about wild groundhogs being groundhogs. More about that behavior…
