Arkansas is quieter in winter than most people realize — not just because of the chill in the air, but because some of its most recognizable wild residents have completely disappeared underground. If you’ve been wondering when marmots come out of hibernation in Arkansas, you’re asking about one of the state’s most fascinating seasonal wildlife events.
Knowing when these stocky, burrowing animals resurface can help you time a wildlife outing, understand what’s happening in your backyard, or simply satisfy a deep curiosity about the rhythms of the natural world. This guide walks you through everything you need to know — from which marmot calls Arkansas home to exactly where you can go to watch one emerge into the spring sunshine.
Which Marmot Species Live in Arkansas
If you picture a marmot and think of the yellow-bellied marmots clinging to rocky alpine slopes out west, you won’t find that species in Arkansas. Yellow-bellied marmots are native to the mountainous region of the western U.S., while groundhogs usually live east of the Rocky Mountains. Arkansas sits firmly in groundhog territory.
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. So when Arkansans talk about seeing a “groundhog” or a “woodchuck,” they are talking about the state’s only true marmot species — and the terms are completely interchangeable.
The groundhog’s range extends down to Georgia, Alabama, Arkansas, and northwestern Louisiana in the east. That makes Arkansas one of the southernmost states where you can reliably encounter this animal in the wild. Also called whistlepigs and land beavers, groundhogs keep winter and summer dens. They’re rarely seen in the Arkansas Delta or southeast Arkansas, but common elsewhere.
Key Insight: Arkansas has only one marmot species — the groundhog (Marmota monax). The western marmot species you may have seen in photos or national park footage do not live here.
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. The groundhog’s preference for open fields, forest edges, and agricultural land makes it perfectly suited to Arkansas’s varied landscape — and far more likely to turn up in a backyard than on a mountain trail.

When Do Marmots Hibernate in Arkansas
Groundhogs are genuine hibernators — not just animals that sleep a little longer in cold weather. The animal is a true hibernator. That distinction matters because what happens inside a hibernating groundhog’s body is dramatic by any measure.
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. For an animal that normally has a heart rate closer to 80 beats per minute, that’s a staggering physiological shift.
In Arkansas specifically, groundhogs may hibernate from November to January or early February. This window is noticeably shorter than what you’d see further north. In most areas, groundhogs hibernate from October to March or April, but in more temperate areas, they may hibernate as little as three months. Groundhogs hibernate longer in northern latitudes than southern latitudes. Arkansas’s relatively mild winters mean the groundhog’s underground stay is briefer than it would be in, say, Maine or Michigan.
Pro Tip: Arkansas groundhogs typically hibernate for a shorter period than their northern counterparts — often just two to three months — because the state’s milder winters don’t demand as long a fast.
Before entering hibernation, groundhogs spend the late summer and early fall eating as much as possible. They feed heavily in summer and early fall, accumulating huge fat reserves for the winter. Instead of storing food, groundhogs stuff themselves to survive the winter without eating. By the time they seal themselves underground, they may have nearly doubled their body weight.
Groundhogs are one of the few species that enter into true hibernation, and often build a separate “winter burrow” for this purpose. This burrow is usually in a wooded or brushy area and is dug below the frost line and remains at a stable temperature well above freezing during the winter months.
For a comparison with how this process plays out in neighboring states, see our guide on when bears come out of hibernation in Louisiana, where similarly mild winters shape a shorter hibernation season.
When Do Marmots Come Out of Hibernation in Arkansas
This is the question most people are really asking — and in Arkansas, the answer comes earlier than you might expect. Groundhogs may hibernate from November to January or early February. That means emergence in Arkansas can begin as early as late January, with most animals surfacing through February.
Groundhogs emerge from hibernation in very early spring, as soon as ground and air temperatures start rising. In the warmer southern portions of the state, you may notice the first signs of activity before February is even halfway through. In the higher elevations of the Ozarks or Ouachitas, emergence may lag by a few weeks.
Important Note: Arkansas groundhog emergence timing varies by region. Animals in the warmer Arkansas River Valley and lowland areas tend to resurface earlier than those in the cooler Ozark and Ouachita highlands.
The timing and duration of hibernation can vary depending on the climate and location. In colder areas, groundhogs might start hibernating in late October and stay in this state until March or April. In milder climates, they might hibernate for shorter periods or not at all. Arkansas sits in the milder end of this spectrum, which is why February sightings are entirely normal here.
There’s also a nuance worth knowing: males and females don’t always emerge at the same time. Male groundhogs leave their winter dens in late February to scout out females and ensure other males are not trespassing. According to outdoor writer Marcus Schneck, “Male groundhogs begin to show themselves later in February, when they begin their annual searches for mates.” Females typically follow a few weeks later.
Groundhogs typically hibernate from late fall through early spring. Spotting groundhogs in the spring is a good indicator that winter is finally over. In Arkansas, that signal often arrives well before the calendar says spring — a reminder that wildlife runs on its own clock.
What Marmots Do Immediately After Hibernation in Arkansas
Waking up from months of deep torpor is not a gentle process. A groundhog doesn’t stretch, yawn, and immediately start grazing. There’s a biological sequence to what happens next, and it’s worth understanding if you want to make sense of what you’re seeing in the field.
As soon as groundhogs wake up, they only have one thing in mind — and it’s not eating. Groundhog mating season begins as soon as the animals wake up in springtime. Male groundhogs wake up, emerge, and immediately start looking for female burrows nearby.
Even with snow still on the ground, males will travel — sometimes surprisingly long distances — throughout their range to inspect the dens of females to see if they are still occupied and to locate other males that might be encroaching on their territory. This is why you might spot a groundhog moving through a frost-covered field in late January or February — it’s not confused about the season. It’s on a mission.
Pro Tip: If you see a groundhog moving quickly across open ground in late winter, it’s almost certainly a male searching for mates. This is one of the best times to observe them in the open before vegetation fills in.
The breeding season extends from early March to mid- or late April, after hibernation. Breeding usually occurs soon after spring emergence; gestation is about 31–32 days and litters are commonly 2–6 pups. By late spring, young groundhogs will begin appearing at burrow entrances — another rewarding sight for patient wildlife watchers.
Once mating is underway, the appetite catches up quickly. Shortly after they go looking for mates, newly-awakened groundhogs remember they haven’t eaten for five months. Groundhogs tend to forage and eat more than ever in spring, especially when they’re caring for newborn babies. They feed on a wide variety of grasses, twigs, plants, flowers, shrubs, and weeds. Adult groundhogs tend to eat over a pound of vegetation every day.
This intense spring feeding is also when groundhogs most frequently come into conflict with gardeners and farmers — something Arkansans who grow vegetables know all too well. If you’re also watching for other animals becoming active around the same time, our article on when snakes come out in Arkansas covers another species that stirs with the warming temperatures.
Where to Spot Marmots in Arkansas
You don’t need to venture deep into the wilderness to find a groundhog in Arkansas. These animals are adaptable and often turn up in surprisingly ordinary places — but knowing their habitat preferences will sharpen your chances of a genuine sighting.
Groundhogs are mostly found in the interior highlands, so the Arkansas River Valley, the Ouachitas, and the Ozarks. If you’re in the Delta or the flat southeast corner of the state, sightings are much rarer. They like forest edges, open fields, and along brushy fencerows. They are rarely found in dense woodlands.
In terms of specific habitats, look for groundhogs in these settings:
- Meadows, woodlots, hay fields, pastures, hedgerows, idle fields, and parks. Dens are usually found in open fields, near fence rows or woodland edges, or under barns, sheds, porches, decks, stone walls, and wood piles.
- Along trail corridors near grassy clearings — the Arkansas River Trail in Little Rock is one local spot where groundhogs have been reported.
- The Ouachita Mountains area, including Queen Wilhelmina State Park, where deer, turkey, bear, raccoons, opossums, groundhogs, chipmunks, and gray squirrels are common.
- Road margins and fence lines through agricultural areas in the Ozark highlands of northwest and north-central Arkansas.
Woodchucks (Marmota monax) can be found throughout most of Arkansas, which means a patient observer in almost any part of the state — outside the Delta — has a reasonable shot at a sighting during the active season.
Twenty-five Arkansas state parks have been selected for inclusion in the Watchable Wildlife program, implemented on a state level by the Arkansas Game and Fish Commission. This national program identifies locations where outstanding outdoor habitats attract Arkansas wildlife and offer you the best chance of viewing wildlife, large and small, in the Arkansas outdoors.
Key Insight: The best time to spot a groundhog in Arkansas is in the early morning or late afternoon, from February through October. Spring is especially productive because vegetation hasn’t fully grown in yet, leaving animals more visible in the open.

How to Tell If a Marmot Is Active in Arkansas
You don’t always need to see the animal itself to know one is nearby. Groundhogs leave behind a clear set of signs, and learning to read them turns any walk through the Arkansas countryside into a more layered experience.
Burrow entrances are the most reliable indicator. You’ll 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. Their burrows feature one main entrance hole and are between 10 and 12 inches in diameter. You’ll typically find a groundhog hole near trees, walls, or fences.
Activity around the entrance also tells a story. You will often see flies around an active burrow. A well-worn trail from entrance to entrance, or to the garden, is another telltale sign. If the soil around the entrance looks freshly disturbed, the burrow is likely occupied and in use.
Feeding evidence is another clue. Evidence of their feeding includes chewed wood and chewing on fresh plants similar to that of rabbits — though it can be difficult to pin on woodchucks without supporting evidence. Cleanly clipped stems of clover, alfalfa, or garden greens at ground level are a strong hint.
Behavior when spotted is distinctive too. 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 their burrow. If you startle one, listen for a loud, shrill whistle — this alarm call is how the groundhog earned the nickname “whistlepig” across parts of the South.
| Sign | What It Looks Like | What It Means |
|---|---|---|
| Main burrow entrance | 10–12 inch hole with dirt mound | Active or recently used den |
| Secondary entrance | Smaller hole, no dirt mound | Escape tunnel, dug from inside |
| Worn trail | Flattened grass path near burrow | Regular movement route |
| Flies at entrance | Cluster of flies near hole | Animal recently inside |
| Clipped vegetation | Stems cut at ground level | Active foraging nearby |
| Alarm whistle | Sharp, high-pitched call | Animal detected a threat |
It’s common to see groundhogs active during the day, especially early morning and late afternoon. Groundhogs can be active at any time, though typically early morning and late evening. Planning your observation around those windows — particularly in February and March when animals are newly emerged and vegetation is still sparse — gives you the best chance of a clear, unhurried look.
If you enjoy tracking seasonal wildlife patterns, you may also find it worthwhile to explore when other animals become active in neighboring states. Our guides on when snakes come out in Ohio, when snakes come out in Pennsylvania, and when bears come out of hibernation in Connecticut offer useful regional context for understanding how latitude and climate shape wildlife timing across the eastern United States.
Arkansas’s groundhog is easy to overlook — a stout, quiet animal that spends a third of its life underground. But watching one emerge on a cool February morning, blinking into the pale winter light, is a reminder that the seasons are shifting whether you’ve noticed yet or not. Step outside, look for the signs, and let the groundhog tell you spring is on its way.
