Brown Bear / Grizzly
Ursus arctos · Ursidae
The apex predator of the American wilderness — hunted only in Alaska, where their populations support a limited season.
Found & hunted in
Overview
The brown bear (coastal) and grizzly bear (interior) are the same species — Ursus arctos — and the continent's most formidable land predator. Grizzlies in the lower 48 are protected under the Endangered Species Act and cannot be hunted. Brown bears in coastal Alaska are huntable with a guided or resident-only hunt and are among the most impressive big-game trophies in the world. A fully mature boar brown bear may stand 10 feet tall on his hind legs and weigh 1,400 lbs. Hunting them requires skill, nerve, and a guide who has experience with dangerous game.
Habitat
Brown bears occupy an extraordinary diversity of terrain across their North American range, from the dense alder and spruce thickets of Alaska's coastal drainages to the high-elevation whitebark pine forests and subalpine meadows of the Greater Yellowstone Ecosystem. Understanding this habitat diversity is fundamental to locating bears at any given time of year, because brown bears are driven almost entirely by caloric need — their entire existence is structured around hyperphagia, the compulsive feeding that must pack on sufficient fat reserves to survive four to six months of winter dormancy.
In coastal Alaska, the most productive brown bear habitat centers on salmon-bearing rivers and streams, particularly during the late summer and fall sockeye, pink, and coho runs. Bears congregate in extraordinary densities at productive fishing sites — falls, shallow riffles, and tidal flats — where the caloric density of a single spawning salmon can reach 4,000 calories. The riparian corridor surrounding these fisheries, heavily vegetated with cow parsnip, sedge, and devil's club, provides both travel corridors and foraging areas during early summer before the salmon arrive.
In the interior and montane environments occupied by grizzlies, habitat quality is measured by the availability of seasonal food sources stacked across the calendar. Spring green-up on south-facing slopes at 4,000 to 6,500 feet draws bears out of dens as early as March in mild years. Summer months shift bears to higher elevations — 7,000 to 9,500 feet in the Northern Rockies — where glacier lily bulbs, army cutworm moths aggregating on talus fields, and early berry crops concentrate animals. By late summer and fall, whitebark pine nut crops, huckleberry fields at mid-elevations, and the carcasses of elk and deer become critical resources. A failed whitebark pine crop, decimated by blister rust and mountain pine beetle in recent decades, can push bears into conflict zones and dramatically alter their spatial distribution heading into the hunting season.
Population
The total North American brown bear population is estimated between 55,000 and 60,000 animals, with the overwhelming majority — roughly 30,000 to 32,000 — residing in Alaska, making it the most important jurisdiction in the world for brown bear conservation and hunting. British Columbia and Yukon together hold an additional 15,000 to 20,000 animals, and Russia's Kamchatka Peninsula supports populations that draw comparison to Alaska's coastal concentrations. These figures represent a genuine conservation success story in the jurisdictions where habitat has remained intact and harvest has been managed conservatively.
In the Lower 48, the picture is dramatically different. The grizzly bear was extirpated from roughly 98 percent of its historical contiguous United States range by the early twentieth century, reduced from an estimated 50,000 animals to fewer than 1,000 by the 1970s. Recovery efforts under the Endangered Species Act have been genuinely successful in the Greater Yellowstone Ecosystem, where the population has grown from roughly 136 animals in 1975 to over 700 today, and in the Northern Continental Divide Ecosystem centered on Glacier National Park, where population estimates now exceed 1,000 bears. Smaller, recovering populations exist in the Cabinet-Yaak and Selkirk ecosystems, with ongoing efforts to establish connectivity between these isolated groups.
Population density varies enormously with habitat productivity. Kodiak Island's bears exist at some of the highest densities on earth — historically estimated at one bear per 1.5 square miles in prime habitat — while interior grizzlies in the Northern Rockies may occupy home ranges of 300 to 800 square miles for males. These density differences have profound implications for hunters: a guided brown bear hunt in coastal Alaska operates in a fundamentally different biological and logistical context than a wilderness grizzly hunt in the Bob Marshall, and hunters must calibrate their expectations accordingly.
Conservation
Brown bear conservation in North America represents one of the most complex intersections of biology, politics, rural livelihoods, and predator-prey dynamics in wildlife management. In Alaska, where populations are robust and habitat remains largely intact, the primary conservation challenges involve managing sustainable harvest levels while maintaining the ecological functions that apex predators perform — regulating prey populations, cycling marine-derived nutrients from salmon carcasses into terrestrial ecosystems, and structuring vegetation communities through their digging and foraging behavior. The Alaska Department of Fish and Game has generally maintained conservative harvest rates, typically removing less than 3 percent of the population annually in any given management unit, a level biologists consider well within sustainable bounds given brown bear reproductive rates.
The situation in the Lower 48 is far more contested. Grizzly bears in the Greater Yellowstone and Northern Continental Divide ecosystems have met or exceeded original recovery goals established under the Endangered Species Act, and the Fish and Wildlife Service has made multiple attempts to delist the populations, which would return management authority to Wyoming, Montana, and Idaho. These delisting efforts have faced sustained legal challenges from conservation organizations, and as of the mid-2020s no sport hunting season has opened in the Lower 48 in the modern era. The scientific debate centers on questions of genetic connectivity between isolated populations, the carrying capacity of available habitat, and the long-term effects of climate change on whitebark pine — a keystone food source — and on salmon in the Pacific Northwest.
For hunters, the conservation calculus is straightforward: North American brown bear hunting, when conducted within managed seasons in Alaska and Canada, generates substantial revenue for wildlife agencies, provides meaningful economic incentive for rural communities and guides to protect habitat and tolerate bears, and creates a constituency with a strong interest in maintaining healthy populations. The Pittman-Robertson Federal Aid in Wildlife Restoration Act, funded by excise taxes on firearms and ammunition, has directed hundreds of millions of dollars into bear habitat protection and research. Indigenous co-management frameworks, particularly in Alaska and British Columbia, integrate traditional ecological knowledge with Western science in ways that are increasingly recognized as best practice in brown bear management.
Subspecies
Currently listed as Threatened under the Endangered Species Act in the contiguous United States, with no authorized sport hunting season. The Greater Yellowstone Ecosystem and Northern Continental Divide Ecosystem populations have both met or exceeded original recovery goals, making future delisting a recurring political and legal question. Hunting opportunities exist in Canada (British Columbia, Alberta) and Alaska for closely related populations.
Managed by the Alaska Department of Fish and Game under a regulated draw and registration permit system. Non-resident hunters are required by Alaska law to use a licensed, registered guide for brown bear hunting. The Alaska Peninsula and Kodiak Archipelago are managed separately, with distinct permit quotas reflecting the extraordinary density and size of bears in those areas.
Managed under a controlled registration permit system by the Alaska Department of Fish and Game in cooperation with the Kodiak National Wildlife Refuge. Permit allocations are tightly controlled given the island's finite carrying capacity and the trophy quality of the population. Non-resident permits are available for both spring and fall seasons with required guide use. The Kodiak National Wildlife Refuge covers approximately two-thirds of Kodiak Island and manages bear populations as the primary wildlife resource.
Diet
True omnivores. Spring: sedge grass, skunk cabbage, carrion (winter-killed ungulates), and digging for roots. Summer: salmon (vital protein source for coastal bears), berries, ground squirrels, caribou calves. Fall (hyperphagia): berries (blueberry, crowberry), roots, salmon, anything calorie-dense before denning. Bears may consume 20,000 calories per day in fall.
Social Behavior
Largely solitary except where food concentrates them (salmon streams, berry patches, sedge flats). Bears establish dominance hierarchies at food sources without fighting — a large boar displaces smaller bears by presence alone. Sows with cubs are given wide berth by other bears due to their unpredictable defense of offspring.
Breeding & Rut
Breeding season May–July. Bears may mate multiple times over several days. Implantation is delayed until fall — if a sow doesn't accumulate enough fat reserves, the embryo doesn't develop. Cubs (1–3, averaging 2) are born in January in the den at less than 2 lbs. They stay with the sow for 2.5 years.
Scouting
- →Time your pre-season scouting around the salmon run calendar for your specific drainage — the Alaska Department of Fish and Game publishes sonar counts for major river systems, and peak sockeye counts typically lag 7 to 14 days behind the fish reaching the spawning grounds where bears concentrate. Scout the riffles, falls, and tidal confluences first, as these are where bears can catch fish with the least effort and where the largest, dominant boars tend to claim the best positions.
- →In interior grizzly country, glass south-facing slopes between 4,500 and 6,500 feet in late April and May for bears freshly emerged from dens feeding on the first green-up of sedges, grasses, and glacier lily. These animals are at their leanest and most visible, and dominant boars will often return to the same aspect and elevation band year after year because those slopes produce the earliest, most nutritious forage.
- →Locate active bear trails by examining alder and willow thickets along stream corridors — well-used travel routes will show matted vegetation, fresh digging for roots and ground squirrels, and often marking trees where bears have rubbed their backs and chewed the bark. These signpost trees, particularly large spruce and cottonwood with visible claw marks and embedded hair, are prime camera locations and indicate the relative size and sex of bears using the corridor.
- →During huckleberry and buffaloberry season — typically August through early October at 4,000 to 7,500 feet in the Northern Rockies — glass open hillsides and burns with heavy berry crops from across drainages in the early morning and evening. A productive berry slope can hold multiple bears simultaneously, and returning to the same slope over multiple mornings allows you to identify individual animals by their coloring, behavior, and the consistent areas they feed in.
- →Use trail cameras on salmon carcass piles and active trails during the pre-season if regulations permit in your management unit. Position cameras at a 45-degree angle to the trail rather than head-on to capture better body profile images for aging and sex determination. Check cameras remotely if possible to avoid depositing human scent near active bear areas in the weeks before the season.
- →Study wind patterns in your hunting area obsessively — brown bears have olfactory capabilities estimated to be seven times more sensitive than a bloodhound, and a bear at 2,000 yards can detect human scent under the right thermal conditions. Learn the valley-specific thermals: cold air drains downslope until mid-morning, then reverses as slopes heat, creating predictable morning and evening windows when you can approach from above or below without contaminating your primary glassing areas.
- →In Alaska coastal areas, invest time scouting from inflatable rafts or skiffs to observe bears at fishing sites without applying ground pressure. Bears that are repeatedly disturbed on the water by human foot traffic will shift their activity to nocturnal patterns or move to less productive but less pressured sites, effectively eliminating hunting opportunity. Observation from water is often the least intrusive way to inventory what bears are in a drainage.
- →Look for fresh diggings as one of the most reliable indicators of recent bear activity in the absence of tracks — grizzlies excavate ground squirrel colonies, pocket gopher mounds, and yampa or biscuitroot plants with extraordinary efficiency, leaving characteristic elongated pit complexes that can turn acres of meadow. Fresh diggings with still-moist soil and green vegetation recently turned indicate bears within hours, while gray, dry-edged diggings are days old.
- →If you're targeting coastal bears during the pre-salmon period — late May through early July — focus on sedge flats at tidal margins and grass meadows in river valleys. Bears emerging from winter and early spring nursing periods are aggressively feeding on sedge rhizomes and first-growth grasses, and these flats concentrate animals similarly to the way salmon sites will in August. This period also offers the advantage of bears being in their most ragged coat, which is actually desirable for judging body size without the confusion of a full fall coat.
- →Mark every fresh track you find and measure the front pad width excluding the claws — a front pad measuring 5 inches or more across typically indicates a mature boar. In coastal Alaska, trophy boars regularly exceed 6 inches of front pad width. Carry a ruler or use the span of your hand as a reference, and record GPS coordinates of large tracks to understand the animal's travel patterns and home range center relative to your planned hunt area.
- →Glass for bears feeding on big game carcasses in the fall, particularly in areas with high elk and deer density. Grizzlies are highly efficient scavengers and will locate and defend carcasses from wolves and other predators — in Yellowstone country, monitoring wolf kill sites can lead you directly to bear activity. Bears feeding on carcasses are typically preoccupied and predictable in their movements, returning to the site multiple times over several days until the food resource is exhausted.
Gear & Calibers
Hunting Tips
- →Non-resident hunters in Alaska are required to be accompanied by a registered guide or an Alaska resident who is a licensed assistant guide to hunt brown bear in most areas.
- →Spring hunts (April–May) target bears emerging from dens, often in good coat condition. Fall hunts (Oct–Nov) target bears in hyperphagia near salmon streams or berry patches.
- →A bear requires calibers adequate for large dangerous game — .338 Win Mag, .375 H&H, .45-70 or larger. Shot placement is behind the shoulder — don't shoot a charging bear in the face.
- →Never approach a downed bear without a second hunter ready to shoot. A bear that appears dead is not always dead.
Stalking Tips
- →Glass coastal tidal flats and sedge meadows for feeding bears. Approach from downwind in open terrain — their nose is extraordinary.
- →Do not get between a sow and her cubs under any circumstances.
Glassing Tips
- →Glass open avalanche chutes, river sedge flats, and tidal zones in April–May for bears feeding after emergence from dens.
- →The prominent hump and dished facial profile distinguish brown bears from black bears at distance.
Trophy Judging
- →The single most reliable field indicator of a large boar is shoulder height and overall body mass relative to surrounding terrain. A mature boar stands 3.5 to 4.5 feet at the shoulder and appears blocky and massive even at long distances — the neck is thick and appears almost as wide as the head, the body has a pronounced concave dip between the shoulders and the rump, and the animal walks with a rolling, pigeon-toed gait that communicates mass. Sows with cubs appear comparatively slender, long-legged, and flat-backed.
- →Ear spacing is a critical and frequently cited field judging technique: on a mature boar, the ears appear small relative to the head and are set far apart, often appearing to almost disappear into the skull when the bear is looking directly at you. On younger bears and sows, the ears are proportionally larger and set closer together, appearing prominent and alert. This difference is exaggerated because skull width grows continuously throughout a boar's life — a 15-year-old Kodiak boar has a skull that is literally wider than a 5-year-old boar's, making the ears look progressively smaller.
- →A mature boar's head, viewed from the front, is dramatically wider than it is tall, giving it a characteristic square, almost rectangular appearance. Sows and young bears have rounder, more vertically proportioned heads. From the side, a trophy boar should have a prominent, dished facial profile — the nose curves slightly upward — and a heavy, jowly dewlap under the chin. These jowls are most pronounced on coastal and Kodiak bears at the peak of fall hyperphagia.
- →Assess the animal's behavior and body language in addition to physical characteristics. A dominant boar moves through a drainage with a confident, purposeful directness — other bears get out of his way, and he does not alter his course for perceived threats. Subordinate males and sows display avoidance and deference behaviors when a trophy boar is near. A bear that is repeatedly displaced from a fishing site by another bear is likely not the largest animal in the area.
- →For skull scoring purposes, measure the greatest length from the tip of the nose to the back of the skull and the greatest width at the widest point, then add them. Boone & Crockett minimum for grizzly is 23 2/16 inches and for Alaska brown bear is 28 inches. In the field, compare the skull width to the length of the ear — on a record-class bear the skull is dramatically wider than the ear is long. Most guides use a 'palm width' comparison: if the skull appears wider than four hand-widths, you are looking at a very large bear.
- →Coat quality matters enormously for a rug or full-body mount. The prime coat in spring is rich and full but often shows winter damage — rubbing on trees and rocks creates bald patches, particularly on the shoulders and haunches. Fall coats achieved peak color and gloss after summer feeding, but the coastal rut in late summer can cause boars to develop fighting wounds that damage the hide. Evaluate coat condition through your spotting scope before committing — patches larger than a hand spread in visible areas will detract substantially from a mounted trophy.
- →Sow determination is a legal and ethical requirement in most brown bear management units — shooting a sow, especially a sow with cubs, carries severe legal penalties and significant conservation consequences. Never fire at a bear accompanied by cubs or at a group of bears until you have identified every animal in the group and are confident your target is an adult male. If there is any doubt about the sex of an animal, do not shoot. Cubs may not be visible due to terrain, vegetation, or distance, making extended observation before shooting a non-negotiable requirement.
- →Age estimation using dental wear requires a skull or jawbone, but in the field, body condition gives useful clues. Prime boars aged 10 to 16 years typically show the combination of maximum body mass and intact coat. Very old bears — 20-plus years — often appear swaybacked, show pronounced muscle wasting over the hindquarters relative to the forequarters, and may have visible facial injuries from decades of fighting. While record skulls can come from very old bears, extreme age often correlates with dental wear that prevents proper feeding and associated weight loss.
Field Care & Dressing
- →Approach a downed brown bear with extreme caution — circle the animal from downwind at 50 yards before closing in, watch for breathing and open eyes, and be prepared for a follow-up shot. Many experienced guides recommend a finisher to the base of the ear on any bear that does not show obvious signs of death. Never approach from directly behind, and always keep your firearm ready until you have confirmed the animal is expired. Accidental 'dead bear' attacks kill hunters every decade in Alaska.
- →Brown bear hide is a primary trophy value, so begin skinning from the belly up the insides of all four legs, keeping the claws attached and the lip lines intact with a full 1 to 1.5 inches of skin beyond the lip margin. The hide on a large boar can weigh 80 to 120 pounds unprepared, and you should salt it immediately and heavily — using a minimum of 25 pounds of non-iodized table salt or canning salt — working the salt into every fold, the face, and between the toes to prevent slippage of the hair.
- →Brown bear fat, particularly from well-fed coastal animals in the fall, is rendered for bear grease — historically one of the most prized and versatile fats in North American hunting cultures, used for waterproofing leather, treating wood, and cooking. The fat layer on a fall coastal bear can be 4 to 6 inches thick over the rump and shoulders. Separate the fat from the meat early in the field dressing process and bag it separately in plastic for rendering back in camp.
- →Trichinella spiralis — the parasitic roundworm responsible for trichinosis — is present in bear populations across North America at rates ranging from 1 to 15 percent depending on region. All bear meat must be cooked to a minimum internal temperature of 160°F throughout, including the center of thick roasts and hams. Do not sample bear meat raw at any stage of field processing, wear disposable nitrile gloves while handling raw meat and internal organs, and treat all cutting surfaces as contaminated until sanitized.
- →Remove the skull carefully if you intend a European mount or full skull trophy — bears are increasingly judged and scored by skull dimensions rather than hide square footage. Score is determined by adding the greatest length and greatest width of the skull in inches; a 28-inch skull is a record-class animal in any subspecies. Clean the skull by removing all meat and placing it in a mesh bag submerged in running water for several days, or use a commercial maceration or beetle colony service. Do not boil skulls, as this weakens the bone and causes the teeth to loosen.
- →In warm weather — which can mean 50°F or higher even in coastal Alaska during August and September — brown bear meat deteriorates rapidly without aggressive cooling. Quarter the animal immediately, remove the gut pile downwind of camp and of your meat cache, and hang quarters in breathable game bags in the shade with maximum airflow. If you cannot achieve adequate cooling naturally, pack bags with snow if available or prioritize flying meat out on the earliest available charter.
- →Bears killed near salmon streams will have meat that smells and tastes strongly of fish, particularly if taken during the peak of the salmon run. The fat carries most of the fishy flavor. Removing all visible fat during processing dramatically improves the flavor of the final product. Marinating bear roasts in acidic solutions — red wine, apple cider vinegar — for 24 to 48 hours before cooking also reduces the intensity of the salmon-fed character. Bears taken on berries and other terrestrial foods earlier in the season produce some of the finest-tasting wild game meat in North America.
Things to Know
- →Grizzly bears (interior populations) in the lower 48 are protected and cannot be hunted. Delisting efforts are ongoing politically.
- →A properly tanned brown bear hide and skull is one of the most impressive trophies in the world.
- →Bear spray is recommended for anyone in brown/grizzly country. It is more effective than a firearm in many attack scenarios — but bear spray does not replace a firearm for hunters pursuing dangerous game.
Terminology
Records
Brown bear and grizzly are the same species but scored in separate B&C categories based on range. Coastal AK bears (brown) generally score higher due to larger skull size from salmon diet.
