Mississippi is not the first place that comes to mind when you think of marmots — and that reaction is completely understandable. Most people associate these stocky, burrowing animals with mountain meadows and rocky western landscapes. But Mississippi does have its own marmot, and if you know where and when to look, you can find it going about its quiet seasonal routines in the northern part of the state.
In this guide, you’ll learn which marmot species calls Mississippi home, when it enters and exits hibernation, what it does immediately after waking up, where to find it, and how to tell whether one is actively using a burrow near you.
Which Marmot Species Live in Mississippi
When most people search for “marmots in Mississippi,” they are actually looking for the groundhog — and that is exactly the right animal. The groundhog (Marmota monax), also known as the woodchuck, is a rodent of the family Sciuridae, belonging to the group of large ground squirrels known as marmots. It is the only marmot species present in Mississippi.
The mix-up between “groundhog” and “marmot” comes down to naming conventions. In eastern North America, people almost exclusively use “groundhog” or “woodchuck,” while in the western U.S. and in Europe, the word “marmot” is standard. Scientifically, though, the taxonomy is clear: groundhogs are marmots, just adapted to lowland life rather than alpine environments.
The groundhog, being a lowland animal, is exceptional among marmots. Other marmots, such as the yellow-bellied and hoary marmots, live in rocky and mountainous areas. These other marmot species tend to live at opposite ends of the country from the groundhog. Yellow-bellied marmots are native to the mountainous region of the western U.S., while groundhogs usually live east of the Rocky Mountains. None of those western species are found in Mississippi.
Groundhogs are distributed from eastern Alaska across the southern half of Canada to the Atlantic Ocean and south in the eastern half of the United States to Arkansas, Mississippi, Alabama, Georgia, South Carolina, and North Carolina. Within Mississippi specifically, woodchucks can be found in the northern region of the state.
Key Insight: Mississippi sits at the southern edge of the groundhog’s natural range. This means populations here are less dense than in northern states, and the animals’ seasonal behavior can differ slightly from their northern counterparts.
Physically, the groundhog is a sturdy, medium-sized mammal. This solitary rodent, measuring 16–26 inches and weighing 4–13 pounds, has brownish-gray fur and powerful digging claws.

When Do Marmots Hibernate in Mississippi
Groundhogs in Mississippi follow the same fundamental hibernation cycle as those elsewhere in their range, though the milder southern climate means the timing can be somewhat compressed compared to northern populations.
All marmots are true hibernators, and this is one of the strongest traits linking the genus. Groundhogs typically enter hibernation in October or November and don’t emerge until late winter or early spring. In Mississippi’s warmer climate, groundhogs tend toward the earlier end of that entry window — often disappearing underground in October after the first significant cold snaps arrive.
When the groundhog enters hibernation, there is a drop in body temperature to as low as 35 degrees Fahrenheit (2 °C), heart rate falls to 4–10 beats per minute, and breathing rate falls to one breath every six minutes. This is a profound physiological shift — the animal is not simply sleeping deeply, but genuinely shutting down many of its core systems.
Pro Tip: Groundhogs prepare for hibernation by eating heavily through late summer and early fall. If you notice one feeding urgently near a field edge in September or October, it is likely in its final weeks of activity before denning up for winter.
They feed heavily in summer and early fall, accumulating huge fat reserves for the winter. In early June, woodchucks’ metabolism slows, and while their food intake decreases, their weight increases by as much as 100% as they produce fat deposits to sustain them during hibernation and late winter. Instead of storing food, groundhogs stuff themselves to survive the winter without eating.
Groundhogs hibernate longer in northern latitudes than southern latitudes. This is an important distinction for Mississippi residents — the groundhogs in your area may only be underground for a few months, rather than the five or six months typical in New England or the upper Midwest. You can compare this pattern to when bears come out of hibernation in Massachusetts to get a sense of how latitude shapes these cycles.
Generally, woodchucks are true hibernators; however, in the southern part of their range, they have been known to stay active throughout the year. In Mississippi, this means you should not be surprised if a groundhog appears briefly on a warm January afternoon — the mild winters here occasionally allow brief periods of surface activity even mid-season.
When Do Marmots Come Out of Hibernation in Mississippi
This is the question most people are asking, and the answer depends on Mississippi’s relatively mild winter climate. In the northern part of the state where groundhogs live, emergence typically begins in late January to mid-February — noticeably earlier than in northern states where snow and cold can keep them underground until March or April.
Males emerge from hibernation before females. Male woodchucks emerge from hibernation earlier than females in order to establish territories, dominance hierarchies, and to search for mates. So the first groundhog you spot in late January in Mississippi is almost certainly a male.
Hibernating woodchucks lose as much as half their body weight by February. They emerge from hibernation with some remaining body fat to live on until the warmer spring weather produces abundant plant materials for food. This is why a freshly emerged groundhog looks noticeably thinner and moves a little more cautiously than it will later in spring.
Important Note: Mississippi’s groundhogs sit at the southern edge of the species’ range, where winters are mild. Do not expect a precise calendar date for emergence — a warm spell in January can bring males out early, while an unusually cold February can delay things by a few weeks.
The timing of their entry and emergence from hibernation is closely tied to local climate conditions and food availability, demonstrating an incredible adaptation to their specific ecological niches. In practice, this means watching the weather is more reliable than watching the calendar. A stretch of days with temperatures regularly above 50°F is often what triggers sustained surface activity in Mississippi groundhogs.
| Region / Latitude | Typical Emergence Window |
|---|---|
| Mississippi (southern range) | Late January – mid-February |
| Mid-Atlantic / Midwest | Late February – early March |
| New England / Northern states | March – early April |

What Marmots Do Immediately After Hibernation in Mississippi
The days immediately following emergence are a busy, purposeful time for groundhogs — even though they look a little rough around the edges after months underground.
They spend time sunning near burrow mouths to warm up after cold nights or after spring emergence. This basking behavior is one of the most reliable signs that a groundhog has recently emerged. You may see one sitting motionless in a sunny patch near a field edge or fence row, soaking up warmth before venturing farther.
Males move quickly from basking to territory-marking and mate-searching. Older, more dominant males hold territories whereas younger males are nomadic. This means that in the first weeks after emergence, you may notice groundhogs traveling across open ground more boldly than they will later in the season — they are on a mission.
The breeding season extends from early March to mid- or late April, after hibernation. Mating takes place during a ten-day period in early March, with the female giving birth in April. Most litters range between 3 and 5 pups.
Pro Tip: In the first week or two after emergence, groundhogs eat whatever is available — bark, dried stems, early green shoots. If they awake out of hibernation before new plant growth, they will eat bark and small branches. As Mississippi’s spring greenery appears, their diet quickly shifts to fresh clover, grasses, and garden plants.
In spring, groundhogs favor clover and other legumes that provide protein after months of fasting. This protein-focused early diet helps them rebuild muscle mass and energy reserves depleted during hibernation. Woodchucks weigh least in spring when they are just out of hibernation and most in fall prior to hibernation.
Where to Spot Marmots in Mississippi
Finding a groundhog in Mississippi requires knowing two things: the right part of the state, and the right type of habitat. Remember that in Mississippi, woodchucks can be found in the northern region of the state, in meadows, woodlots, hay fields, pastures, hedgerows, and idle fields.
The habitat preference is consistent and predictable. Groundhogs most commonly live along forest edges abutting meadows. They prefer meadows, pastures, crop fields, and yards that are close to a woods edge. They are common in brushy or weedy areas along fence rows or road right-of-ways.
Burrow location is your best clue. Dens are usually found in open fields, near fence rows or woodland edges, and under barns, sheds, porches, decks, stone walls, and wood piles. Once you identify a likely burrow, the groundhog will often return to the same site year after year.
Key Insight: Groundhogs are rare or absent in Mississippi’s Delta lowlands. They are rare in the Mississippi Lowlands, where the water table is so high that denning sites are limited. Focus your search on the hilly terrain of the northern counties instead.
The best times to observe groundhogs are early morning and late afternoon. Groundhogs are mostly diurnal and are often active early in the morning or late afternoon. Woodchucks usually feed twice daily during the summer, with each feeding session lasting no more than 2 hours. They are often found sunning themselves in the middle of the day during summer.

How to Tell If a Marmot Is Active in Mississippi
You don’t always need to see the groundhog itself to know one is present. Several reliable signs can tell you whether a burrow is currently occupied and in active use.
Look at the burrow entrance. You will see a large mound of dirt and stones by the main entrance to their burrow; the secondary entrances, which were dug from the inside, generally don’t have a dirt mound by their opening. Fresh, loose soil at the main entrance is a strong indicator of recent activity.
Check for flies and worn trails. You will often see flies around an active burrow. Scat is rarely seen because woodchucks excavate a privy off their main burrow. A well-worn trail from entrance to entrance, or to the garden, is another reliable sign.
Watch for basking behavior. Adults are often seen basking in the sun, in a grassy area, on a fence post, stone wall, large rock, or fallen log — always near the burrow. If you see a groundhog perched upright in a sunny spot close to a burrow, it is actively using that den.
Listen for alarm calls. When alarmed, groundhogs use a high-pitched whistle to warn others of danger, hence the name “whistle-pig.” If you hear a sharp, piercing whistle near a field edge and then see movement disappearing underground, a groundhog has detected you first.
- Fresh soil mound at the main burrow entrance
- Worn paths leading between burrow openings or toward a garden
- Flies hovering near the entrance hole
- Chewed vegetation or stripped bark near the burrow
- Basking animal visible on sunny mornings near the den
- Sharp whistle followed by rapid disappearance underground
Common Mistake: Many people assume a burrow is abandoned because they don’t see the animal. Groundhogs spend a large portion of the day underground even when active. Check the entrance for fresh soil disturbance and return at dawn or dusk for the best chance of a sighting.
Understanding seasonal animal behavior is a rewarding way to connect with the natural world around you. Whether you’re a landowner monitoring your property or simply a curious observer, knowing that Mississippi’s northern counties host a quiet population of these ancient hibernators adds a new layer to every early spring walk.
