When Do Bears Come Out of Hibernation in Vermont? What You Need to Know

Vermont’s black bears are waking up earlier than ever — and in 2026, wildlife officials are already receiving reports of active bears across the state as of mid-March. If you live, hike, or spend time outdoors in the Green Mountain State, understanding when bears emerge from their dens and what drives that timing can make a real difference in how safely you coexist with them.

In this guide, you’ll learn when Vermont bears enter and exit their winter dens, which species call the state home, what bears do right after emerging, where they’re most commonly spotted, and how to keep yourself and your property safe throughout bear season.

Key Insight: Vermont’s bear emergence has shifted roughly two weeks earlier over the past 15 years — from around April 1 to mid-March — driven largely by shorter, milder winters.

When Do Bears Hibernate in Vermont?

Food supplies are the most critical factor determining when bears den in the fall. When foods are abundant, bears will continue eating throughout the snows of November and into December. When fall foods are scarce, most bears den by mid-November.

Bears typically den in fall, between late October and early December. This window isn’t fixed — it shifts based on how productive the natural food landscape has been. In preparation for the long, foodless months ahead, black bears enter a state of intense, obsessive eating known as hyperphagia. During this period, their sole focus is on consuming as many calories as possible to build up substantial fat reserves. A bear might forage for up to 20 hours a day, consuming tens of thousands of calories.

The den is commonly a brush pile, but it may also be a pocket or cave in rocky ledges, a hollow in a large tree or fallen log, a sheltered depression dug out at the base of a log, tree, or upturned root, or even a simple hole dug into a hillside. Male bears den up almost anywhere, while females are more particular, selecting protected sites and lining them with stripped bark, leaves, grasses, ferns, or moss.

Although bears are often thought to hibernate, they are not true hibernators. A bear’s respiration and metabolic rate do decrease during the winter sleep, but its temperature remains close to normal. Thus a bear in a winter den can be easily aroused within moments, whereas in a true hibernator, it may take several hours.

Pro Tip: Bears in Vermont can occasionally step outside their dens during mild winter warm spells and then return. Don’t assume a bear sighting in February means full emergence — they may simply be checking conditions before heading back in.

Black bears can hibernate up to 7 months out of the year. During this period, the bears don’t eat, drink, exercise, defecate, or urinate. Due to the lack of food intake, their metabolic rate is cut in half. Their heart rate drops from 60–80 beats per minute to 8–40 beats, meaning they take one breath every 45 seconds.

When Do Bears Come Out of Hibernation in Vermont?

In Vermont, bears come out of hibernation between mid-March and mid-April. However, that window has been shifting. The time of year that bears emerge from their dens has crept earlier and earlier over past decades, likely driven in part by a changing climate that has made Vermont winters shorter and less severe. In Vermont, the emergence has shifted about two weeks earlier over the past 15 or so years, from around April 1 to mid-March.

While female bears with new cubs will hibernate until April, other bears will emerge from their dens once enough snow recedes and temperatures warm. Some bears will come out of their dens during winter warm snaps and then go back in if it’s early enough in the season. Individuals may be active on the landscape early if they’ve been disturbed from their den. Male bears also tend to be active earlier than females with cubs — the latter usually stay denned up through March even if the weather is warm.

Bears are relatively “light sleepers” who go into hibernation only once the landscape is rendered barren of food sources. Throughout the winter they will occasionally rouse themselves and step out of the den to assess what’s going on outside. “In a year like this — where it’s been mild, there’s not a lot of snow for the most part — there’s not a lot constraining them to stay in those dens.” Some will go on brief walkabouts and if they just start finding food, and can consistently keep finding food, they will stay active.

Important Note: As of March 2026, Vermont wildlife officials are already receiving reports of bears emerging from hibernation and urging residents to bear-proof their yards now — not in April.

Vermont’s patterns closely mirror those of its neighbors, though local terrain and food availability can create meaningful differences.

Which Bear Species Are Found in Vermont?

The black bear (Ursus americanus) is the smallest of the three bear species found in North America and is the only bear found in Vermont. You won’t encounter grizzly bears or polar bears here — the black bear is Vermont’s sole ursid resident, and it’s thriving.

The state’s bear population has grown over recent years, from between 4,000 and 6,000 bears in 2018 to between 6,500 and 8,000 bears in 2024, according to population estimates by the state. The latest count is nearly double the objective of 3,500 to 5,500 bears, as outlined by a Vermont Fish and Wildlife Department population model.

Black bears are members of the order Carnivora, which also includes dogs, cats, weasels, and raccoons. Despite this classification, they are overwhelmingly omnivorous in practice. Bears are omnivorous and their diets vary seasonally, consisting mostly of plant material, but also including small mammals, carrion, and garbage.

Vermont black bears are relatively shy animals and are seldom seen by people. This is an important factor influencing bear distribution, as Vermont bears prefer wild areas with fewer people. The best habitat for black bears in Vermont is a mixture of coniferous trees, hardwoods, wetlands, and variation in terrain. Because they need dense cover to escape danger, the wary and elusive black bears prefer rough and wooded habitats.

What Bears Do Immediately After Hibernation in Vermont

The first few weeks after a Vermont bear leaves its den are defined by one overriding priority: food. After months without eating, drinking, or moving significantly, their bodies are running on depleted fat reserves and they need calories fast.

As bears emerge from their dens in early spring, they’re on the search for food. That can lead them to backyard beehives, birdfeeders, compost piles, and even chicken coops. Natural food sources are still scarce in early spring, which is precisely why human attractants become such a powerful draw at this time of year.

Some bears are finding the remains of last year’s abundant beechnut crop, one of their preferred delicacies. Others are checking out backyards. The bears that find food in residential areas quickly learn to return. Bears have very good memories and are rather long-lived, surviving into their 20s and, on rare occasions, their 30s. “They are very good at remembering where they got food because their foods are not uniformly distributed across the landscape.” If they got a bird feeder from your backyard once, they will, for years, go back and just double-check to see if that food source is back.

Common Mistake: Leaving bird feeders up into March or April. Vermont wildlife officials now recommend removing feeders by mid-March — not April 1 — because bears are already active and actively seeking easy food sources.

When bears get food from human sources, they often keep coming back for more. That repeated behavior can lead to conflict with bears, and can be passed down generationally as moms teach cubs where to look for food. After all, a bear in a yard today means more bears likely in the future.

Female bears with newborn cubs have a slightly different post-hibernation timeline. January is the birth month for black bears. Cubs, when born, weigh less than a pound, are about 7 inches long, their eyelids are closed, and they have no teeth. These mothers remain denned longer — typically into April — to protect their young before venturing out.

Bear Activity Hotspots to Watch in Vermont

Black bears in Vermont are not evenly distributed across the landscape. Knowing where activity tends to concentrate helps you stay alert in the right places and at the right times of year.

Bears live everywhere in the state besides the Champlain Islands, according to the Vermont Fish and Wildlife Department. That said, certain areas see far more reported incidents than others.

The estimated black bears living in Vermont are concentrated in the spine of the Green Mountains, and their habitat overlaps with the Long Trail and other trail systems. If you’re hiking in this corridor — especially during spring emergence or fall hyperphagia — bear encounters become more likely. In the 2021 hiking season, there were reports of bears accessing or attempting to access hiker food at shelters in the south, including Clarendon, Story Spring, Kent Pond, and Boyce shelters.

Stowe has been a hot spot of bear activity in recent years, potentially due in part to out-of-state tourists who are not always aware of best practices to prevent attracting bears. Reports of bears frequenting human areas have also been on the rise in the towns of Middlebury, East Montpelier, Lyndonville, Waterbury, Duxbury, Bolton, Killington, Richmond, and Addison.

Bears have been reported hitting bird feeders, getting into garages, and traipsing across porches across the state, from the southern Green Mountains to the greater Burlington area, and the Connecticut River Valley.

• Green Mountains spine: Core bear habitat; highest density of resident bears year-round
• Stowe area: A consistent hotspot, particularly during tourist season when food attractants increase
• Connecticut River Valley: Active corridor during spring emergence and fall foraging
• Suburban edges in central Vermont: Towns like Waterbury, Bolton, and Richmond see rising incident reports
• Long Trail shelters: Campsites and shelters in the southern Green Mountains are known bear interaction zones

In the mountains, beechnuts are bears’ primary fall food source, but the trees’ nut production pulses every two or three years. Historically, bear populations have risen and fallen with these cycles. In the valleys, oak trees — and thus, acorns — are more abundant and more consistent. This means valley-adjacent communities can see increased bear pressure in years when mountain food sources are poor.

If you’re also watching for other wildlife in Vermont during spring, it’s worth knowing when snakes come out in Vermont — another species that becomes active around the same time bears are emerging. And for those curious about what natural threats bears themselves face, you can explore predators of bears and what animals eat bears for a fuller ecological picture.

How to Stay Safe During Bear Season in Vermont

Staying safe around Vermont’s black bears is less about dramatic encounters and more about consistent, everyday habits. Although it is extremely rare for a black bear to attack a human, bears are wild animals and should never be approached. The goal is to reduce the conditions that bring bears into close contact with people in the first place.

At Home: Remove Food Attractants

Reports from the public strongly show that garbage is the biggest source of conflicts between people and bears. Food scraps going into compost is also a big issue in Vermont. Taking these steps before bears arrive in your yard is far more effective than reacting after the fact.

• Take down bird feeders by mid-March — “Mid-March is the time for Vermonters to take down our birdfeeders, make sure our garbage is secure, and protect our backyard chickens and bees with an electric fence,” according to Vermont Fish and Wildlife bear biologist Jaclyn Comeau.
• Secure your trash: Store garbage containers inside a secure structure, like a garage, a basement, or a secure shed.
• Protect livestock and bees: Store trash and compost in bear-resistant containers and put electric fences around chicken coops and bee hives.
• Feed pets indoors: Feed pets indoors and clean your grill after every use, storing it somewhere secure between uses.
• Manage compost carefully: Compost needs to be three parts brown/decomposed material for every one part of fresh kitchen scraps and turned often to avoid attracting bears.

Pro Tip: It’s illegal to feed bears in Vermont. Even unintentional feeding — like leaving garbage accessible — can condition bears to return and ultimately result in the animal being put down for public safety reasons.

On the Trail: Food Storage and Awareness

Black bears are typically skittish — unlike their grizzly cousins — which makes it unlikely you’ll see one. However, temptations such as food can draw a bear into human-designated zones like campsites. When hiking or camping in Vermont’s backcountry, proper food storage is non-negotiable.

• Hung food bags should be 200 feet from campsites, water sources, and trails; 12 feet from the ground; and 6 feet from the tree trunk and nearby branches.
• All smellable items — including food, trash, toiletries, and cookware — should go in critter-proof storage. That includes deodorant, lip balm, hand sanitizer, period products, utensils, gum, snacks, and wrappers.
• Use a certified bear canister or Ursack as a reliable alternative to food hangs, especially in areas with known bear activity.

If You Encounter a Bear

The most important thing to do when seeing a bear is to scare it with loud noise from a safe distance so that it associates backyards with negative experiences and remains in the wild. If a bear doesn’t flee from the noise, it has likely already been rewarded with food. It is critical to make sure these bears have no reason to return by removing all food attractants.

• When there is a bear physically present, bring children and pets inside. However, reports of bear sightings in the area should not deter people from enjoying time outdoors or from allowing children to play outside.
• Scare bears away from your yard by yelling, banging pots, or using other noise makers from safely inside your house. Never shoot a bear to scare it — even BBs can seriously injure a bear.
• Never run from a bear. Back away slowly while making yourself appear large and speaking in a calm, firm voice.

When to Report Bear Activity

Report a bear incident to Vermont Fish and Wildlife when there is property damage by bears; visits to birdfeeders, compost bins or garbage; bears on porches or decks; damage to beehives, corn or other crops; and/or bears in campgrounds or campsites.

A bear who comes by regularly, sniffs at vehicles and dumpsters, approaches buildings, or shows up in more developed neighborhoods is considered risky behavior and warrants a report. You can contact Vermont Fish and Wildlife at 802-828-1000 or through their Living with Black Bears reporting page.

Key Insight: Being proactive protects bears as well as people. The state and private residents kill upwards of 40 bears a year whose behavior presents a danger to the public, like breaking into cars, killing livestock, or causing extensive property damage. Removing attractants early keeps bears wild and alive.

Vermont’s bear season is a year-round reality that peaks in spring and fall. By understanding when bears emerge, where they roam, and what draws them toward people, you’re already better prepared to share the landscape responsibly.
