The
brown bear (
''Ursus arctos'') is a large
bear distributed across much of northern
Eurasia and
North America. It can weigh from and its largest subspecies, the
Kodiak Bear, rivals the
polar bear as the largest member of the bear family and as the largest land-based predator.
There are several recognized subspecies within the brown bear species. In North America, two types are generally recognized, the coastal brown bear and the inland grizzly, and the two types could broadly define all brown bear subspecies. Grizzlies weigh as little as 350 lb (159 kg) in Yukon, while a brown bear, living on a steady, nutritious diet of spawning salmon, from coastal Alaska and Russia can weigh 1,500 lb (682 kg). The exact number of overall brown subspecies remains in debate.
While the brown bear's range has shrunk, and it has faced local extinctions, it remains listed as a least concern species by the IUCN, with a total population of approximately 200,000. Its principal range countries are Russia, the United States (mostly in Alaska), Canada, the Carpathian region (especially Romania, but also Ukraine, Slovakia, and so on), the Balkans, Sweden and Finland, where it is the national animal. The brown bear is the most widely distributed of all bears.
Naming and etymology
The brown bear is sometimes referred to as the ''
bruin'', from
Middle English, based on the name of the bear in ''History of
Reynard the Fox'', translated by
William Caxton, from
Middle Dutch ''bruun'' or ''bruyn'', meaning ''
brown'' (the color). During the
Old West, the grizzly was termed "Old Ephraim" and sometimes as "Moccasin Joe".
Taxonomy and evolution
Brown bears are thought to have evolved from ''Ursus etruscus''. The oldest fossils occur in China from about 0.5
million years ago. They entered Europe about 250,000 years ago, and North Africa shortly after. Brown bear remains from the Pleistocene period are common in the
British Isles, where it is thought they outcompeted
cave bears. The species entered Alaska 100,000 years ago, though they did not move south until 13,000 years ago. It is thought brown bears were unable to migrate south until the extinction of the much larger ''
Arctodus simus''. Several paleontologists suggest the possibility of two separate brown bear migrations: grizzlies are thought to stem from narrow-skulled bears which migrated from northern Siberia to central Alaska and the rest of the continent, while Kodiak bears descend from broad-skulled bears from Kamchatka, which colonized the Alaskan peninsula. Brown bear fossils discovered in Ontario, Ohio, Kentucky and Labrador show the species occurred farther east than indicated in historic records.
Subspecies
There is little agreement on classification of brown bears. Some systems have proposed as many as 90 subspecies, while recent DNA analysis has identified as few as five clades. DNA analysis recently revealed that the identified subspecies of brown bears, both Eurasian and North American, are genetically quite homogeneous, and that their genetic
phylogeography does not correspond to their traditional taxonomy. As of 2005, 16 subspecies have been recognized. The subspecies have been listed as follows:
Hybrids
A grizzly–polar bear hybrid (known as a ''pizzly Bear'' or ''grolar bear'') is a rare
ursid hybrid resulting from a union of a brown bear and a
polar bear. It has occurred both in captivity and in the wild. In 2006, the occurrence of this hybrid in nature was confirmed by testing the
DNA of a strange-looking bear that had been shot in the
Canadian arctic. Previously, the hybrid had been produced in
zoos, and was considered a "
cryptid" (a hypothesized animal for which there is no scientific proof of existence in the wild).

Physical description
Brown bears have very large and curved claws, those present on the forelimbs being longer than those on the hind limbs. They may reach and sometimes along the curve. They are generally dark with a light tip, with some forms having completely light claws. Brown bear claws are longer and straighter than those of American black bears. The claws are blunt, while those of a black bear are sharp.
Adults have massive, heavily built concave skulls, which are large in proportion to the body. The forehead is high and rises steeply. The projections of the skull are well developed when compared to those of Asian black bears: the latter have sagittal crests not exceeding more than 19–20% of the total length of the skull, while the former have sagittal crests comprising up to 40–41% of the skull's length. Skull projections are more weakly developed in females than in males. The braincase is relatively small and elongated. There is a great deal of geographical variation in the skull, and presents itself chiefly in dimensions. Grizzlies, for example, tend to have flatter profiles than European and coastal American brown bears. Skull lengths of Russian bears tend to be for males, and for females. The width of the zygomatic arches in males is , and in females. Brown bears have very strong teeth: the incisors are relatively big and the canine teeth are large, the lower ones being strongly curved. The first three molars of the upper jaw are underdeveloped and single crowned with one root. The second upper molar is smaller than the others, and is usually absent in adults. It is usually lost at an early age, leaving no trace of the alveolus in the jaw. The first three molars of the lower jaw are very weak, and are often lost at an early age. Although they have powerful jaws, brown bear jaws are incapable of breaking large bones with the ease of spotted hyenas.
The dimensions of brown bears fluctuate very greatly according to sex, age, individual, geographic location, and season. The normal range of physical dimensions for a brown bear is a head-and-body length of 1.7 to 2.8 meters (5.6 to 9.2 ft) and a shoulder height of 90 to 150 centimeters (35–60 in). The smallest subspecies is the Eurasian brown bear, whose mature females weigh as little as . Barely larger, grizzly bears from the Yukon region (which are a third smaller than most grizzlies) can weigh as little as in the spring and the Syrian brown bear, with mature females weighing as little as . The largest subspecies are the Kodiak bear, Siberian brown bear, and the bears from coastal Russia, Alaska, and British Columbia. It is not unusual for large males in coastal regions to stand over while on their hind legs, and to weigh up to . The heaviest recorded brown bear weighed over .
Brown bears have long, thick fur, with a moderately long mane at the back of the neck. In India, brown bears can be reddish with silver tips, while in China, brown bears are bicolored with a yellow-brown or whitish cape across the shoulders. North American grizzlies can be dark brown (almost black) to cream (almost white) or yellowish brown. Black hairs usually have white tips. The winter fur is very thick and long, especially in northern subspecies, and can reach at the withers. The winter hairs are thin, yet rough to the touch. The summer fur is much shorter and sparser, and its length and density varies geographically.
Distribution and habitat
There are about 200,000 brown bears in the world. The largest populations are in Russia with 120,000, the United States with 32,500, and
Canada with 21,750. About 95% of the brown bear population in the United States is in Alaska, though in the lower 48 states, they are repopulating slowly but steadily along the
Rockies and the western
Great Plains. Although many people hold the belief some brown bears may be present in
Mexico and the
Atlas Mountains of
Morocco, both are almost certainly extinct. The last Mexican brown bear was shot in 1960. In
Europe, there are 14,000 brown bears in ten fragmented populations, from
Spain (estimated at only 20-25 animals in the
Pyrenees in 2010, in a range shared between
France,
Spain and
Andorra, and some 85-90 animals in
Asturias,
Cantabria,
Galicia and
León, in the
Picos de Europa and adjacent areas in 2003 and some 100 animals in 2005) in the west, to
Russia in the east, and from
Sweden and
Finland in the north to
Romania (4000–5000),
Bulgaria (900–1200),
Slovakia (with about 600–800 animals),
Slovenia (500-700 animals) and
Greece (with about 200 animals) in the south. They are extinct in the
British Isles, extremely threatened in
France and
Spain, and in trouble over most of
Central Europe. The Carpathian brown bear population of
Romania is the largest in Europe outside Russia, estimated at 4,500 to 5,000 bears, although declining alarmingly due to overhunting. There is also a smaller brown bear population in the Carpathian Mountains in
Ukraine (estimated at about 200 in 2005),
Slovakia and
Poland (estimated at about 100 in 2009 in the latter country). The total Carpathian population is estimated at about 8,000.
Northern Europe is home to a large bear population, with an estimated 2,500 (range 2,350–2,900) in
Sweden, about 1,600 in
Finland, about 700 in
Estonia and 70 in
Norway. Another large and relatively stable population of brown bears in Europe, consisting of 2,500–3,000 individuals, is the Dinaric-Pindos (Balkans) population, with contiguous distribution in northeast
Italy,
Slovenia,
Croatia,
Bosnia and Herzegovina,
Serbia,
Montenegro,
Macedonia,
Albania,
Bulgaria and
Greece.
Brown bears were once native to Asia, the Atlas Mountains in Africa, Europe, and North America, but are now extinct in some areas, and their populations have greatly decreased in other areas. They prefer semiopen country, usually in mountainous areas.
Brown bears live in Alaska, east through the Yukon and Northwest Territories, south through British Columbia and through the western half of Alberta. Small populations exist in the Greater Yellowstone Ecosystem of northwest Wyoming (with about 600 animals), the Northern Continental Divide Ecosystem of northwest Montana (with about 750 animals), the Cabinet-Yaak Ecosystem of northwest Montana and northeast Idaho (with about 30–40 animals), the Selkirk Ecosystem of northeast Washington and northwest Idaho (with about 40–50 animals), and the North Cascades Ecosystem of northcentral Washington (with about 5–10 animals). These five ecosystems combine for a total of roughly 1,470 wild grizzlies still persisting in the contiguous United States. Unfortunately, these populations are isolated from each other, inhibiting any genetic flow between ecosystems. This poses one of the greatest threats to the future survival of the grizzly bear in the contiguous United States.
In Asia, brown bears are found in most of Russia, parts of the Middle East, and in a small area of Manchuria in China. They can also be found on the island of Hokkaidō in Japan, western China, and parts of North Korea, Afghanistan and India.
The population of brown bears in the Pyrenees mountain range between France and Spain is so low, estimated at 14 to 18, with a shortage of females, that bears, mostly female, from Slovenia were released in spring 2006 to reduce the imbalance and preserve the species' presence in the area, despite protests from French farmers.
A small population of brown bears (Ursus arctos marsicanus) still lives in central Italy (Apennine mountains, Abruzzo and Latium), with no more than 70 individuals, protected by strong laws, but endangered by the human presence in the area.
In Arctic areas, the potential habitat of the brown bear is increasing. The warming of that region has allowed the species to move farther north into what was once exclusively the domain of the polar bear. In non-Arctic areas, habitat loss is blamed as the leading cause of endangerment, followed by hunting.
North American brown bears, or grizzly bears, seem to prefer open landscapes, whereas in Eurasia they inhabit mostly dense forests. It is thought the Eurasian bears which colonized America were tundra-adapted. This is indicated by brown bears in the Chukotka Peninsula on the Asian side of Bering Strait, which are the only Asian brown bears to live year-round in lowland tundra like their North American cousins.
Behavior
The brown bear is primarily
nocturnal. In the summer, it gains up to of
fat, on which it relies to make it through winter, when it becomes very lethargic. Although they are not full
hibernators, and can be woken easily; both sexes like to
den in a protected spot, such as a
cave, crevice, or hollow log, during the winter months. Brown bears are mostly solitary, although they may gather in large numbers at major food sources and form social hierarchies based on age and size. Adult male bears are particularly aggressive and are avoided by adolescent and subadult males. Female bears with cubs rival adult males in aggression, and are more intolerant of other bears than single females. Young adolescent males tend to be least aggressive, and have been observed in nonagonistic interactions with each other. In his ''Great Bear Almanac'', Gary Brown lists 11 different sounds bears produce in 9 different contexts. Sounds expressing anger or aggravation include growls, roars, woofs, champs and smacks, while sounds expressing nervousness or pain include woofs, grunts and bawls. Sows will bleat or hum when communicating with their cubs.
Reproduction
The mating season is from late May to early July. Being serially
monogamous, brown bears remain with the same mate from several days to a couple of weeks. Females mature sexually between the age of 5 and 7 years, while males usually mate a few years later, when they are large and strong enough to successfully compete with other males for mating rights.
thumb|200px|left|A pair of mating brown bears, at the Bärengraben in [[Old City of Bern|Bern, Switzerland]] Males, however, take no part in raising their cubs – parenting is left entirely to the females.
Through the process of delayed implantation, a female's fertilized egg divides and floats freely in the uterus for six months. During winter dormancy, the fetus attaches to the uterine wall. The cubs are born eight weeks later, while the mother sleeps. If the mother does not gain enough weight to survive through the winter, the embryo does not implant and is reabsorbed into the body. The average litter has one to four cubs, usually two. There have been cases of bears with five cubs, although females sometimes adopt stray cubs. Older females tend to give birth to larger litters. The size of a litter also depends on factors such as geographic location and food supply. At birth, the cubs are blind, toothless, hairless, and weigh less than . They feed on their mother's milk until spring or even early summer, depending on climate conditions. At this time, the cubs weigh and have developed enough to follow her and begin to forage for solid food.
Cubs remain with their mother from two to four years, during which time they learn survival techniques, such as which foods have the highest nutritional values and where to obtain them; how to hunt, fish, and defend themselves; and where to den. The cubs learn by following and imitating their mother's actions during the period they are with her. Brown bears practice infanticide. An adult male bear may kill the cubs of another bear either to make the female sexually receptive or simply for consumption. Cubs flee up a tree when they see a strange male bear, and the mother defends them, even though the male may be twice her size.
Dietary habits
They are
omnivores and feed on a variety of plant products, including berries,
roots, and
sprouts, and
fungi, as well as meat products such as
fish,
insects, and small
mammals. Despite their reputation, most brown bears are not highly carnivorous, as they derive up to 90% of their dietary
food energy from vegetable matter. Their jaw structure has evolved to fit their dietary habits. Their diet varies enormously throughout their differing areas based on opportunity. For example, bears in Yellowstone eat an enormous number of
moths during the summer, sometimes as many as 40,000 in a day, and may derive up to half of their annual food energy from these insects. In the Kamchatka peninsula and parts of coastal Alaska, brown bears feed mostly on spawning
salmon, whose nutrition and abundance explain the enormous size of the bears in these areas, though, these bears very rarely hunt large animals. Brown bears also occasionally prey on large mammals, such as
deer (including
elk,
moose and
caribou),
bighorn sheep,
mountain goats,
bison and
muskoxen. When brown bears attack these animals, they tend to choose the young ones, as they are easier to catch. When hunting, the bear pins its prey to the ground and then tears and eats it alive. On rare occasions, bears kill by hitting their prey with their powerful forearms, which can break the necks and backs of large prey, such as moose. They also feed on
carrion, and use their size to intimidate other predators, such as
wolves,
cougars,
tigers, and
black bears from their kills.
Interspecific predatory relationships
Brown bears often use their large size for intimidation when a kill or a territory is in dispute with another large predator and they are normally dominant in such interactions. Sometimes, the conflict will escalate to the point of violence, but usually threat displays are sufficient, since most animals try to avoid potential bodily harm. However, the massive strength and size of the brown bear will usually result in it winning violent conflicts, even against wolf packs and Siberian Tigers. In situations where the interspecies conflict turns deadly, brown bears may also eat the competitor, despite it not being the primary reason for attack.
Brown bears regularly intimidate wolves away from their kills. In Yellowstone National Park, brown bears pirate wolf kills so often, Yellowstone's Wolf Project Director Doug Smith wrote, "It's not a matter of if the bears will come calling after a kill, but when." Though conflict over carcasses is common, on rare occasions the two predators tolerate each other on the same kill. Given the opportunity, both species prey on the other's cubs. Conclusively, the individual power of the bear against the collective strength of the wolf pack usually results in a long battle for kills or domination. In some areas, the brown bear also regularly displaces cougars from their kills.
Adult bears are generally immune from predatory attacks from anything other than other bears. Some bears emerging from hibernation seek tigers to steal their kills. Indeed, Russian researchers have identified "satellite bears" who "follow tigers over extensive periods of time, sequentially usurping kills"; these bears were observed tracking tigers in spring snow and regularly usurped their kills. In the Russian Far East, brown bears along with smaller Asiatic black bears constitute 5–8% of the diet of Siberian tigers. In particular, the brown bear's input is estimated to be 1.0–1.5% in one source. However, another source states that such attacks are rare and do not have any actual significance because Siberian tigers are almost extinct. Siberian tigers most typically attack brown bears in the winter in the hibernaculum or in the late autumn and early spring, and when ungulate populations decrease. Adult bears, generally smaller ones, are sometimes vulnerable to tiger attacks and have been killed in their dens in winter, with the tiger taking advantage of the bear's hibernating condition. There are also records of bears killing tigers, including fully grown adult males and tigers whose sex and age were not specified, either in self defense, or in disputes over kills or for consumption.
Brown bears usually dominate other bear species in areas where they coexist. Due to their smaller size, American black bears are at a competitive disadvantage to brown bears in open, unforested areas. Although displacement of black bears by brown bears has been documented, actual interspecific killing of black bears by brown bears has only occasionally been reported. Confrontation is mostly avoided due to the black bear's diurnal habits and preference for heavily forested areas, as opposed to the brown bear's largely nocturnal habits and preference for open spaces. Brown bears may attack Asian black bears. They will eat the fruit dropped by the latter species from trees, as they themselves are too large and cumbersome to climb.
There has been a recent increase in interactions between brown bears and polar bears, theorized to be caused by climate change. Brown bears have been seen moving increasingly northward into territories formerly claimed by polar bears. Brown bears tend to dominate polar bears in disputes over carcasses, and dead polar bear cubs have been found in brown bear dens.
Relationship with humans
Bears become attracted to human-created food sources, such as garbage dumps, litter bins, and dumpsters; they venture into human dwellings or
barns in search of food as humans encroach into bear habitats. In the U.S., bears sometimes kill and eat farm animals. When bears come to associate human activity with a "food reward", they are likely to continue to become emboldened; the likelihood of human-bear encounters increases, as they may return to the same location despite relocation. The saying,
"a fed bear is a dead bear", has come into use to popularize the idea that allowing bears to scavenge human garbage, such as trash cans and campers' backpacks,
pet food, or other food sources that draw the bear into contact with humans, can result in a bear's death.
Relocation of the bear has been used to separate the bear from the human environment, but it does not address the problem of the bear's newly-learned association of humans with food or the environmental situations which created the human-habituated bear. "Placing a bear in habitat used by other bears may lead to competition and social conflict, and result in the injury or death of the less dominant bear."
Yellowstone National Park, an enormous reserve located in the western United States, contains prime habitat for the grizzly bear (''Ursus arctos horribilis''), and due to the enormous number of visitors, human-bear encounters are common. The scenic beauty of the area has led to an influx of people moving into the area. In addition, because there are so many bear relocations to the same remote areas of Yellowstone, and because male bears tend to dominate the center of the relocation zone, female bears tend to be pushed to the boundaries of the region and beyond. As a result, a large proportion of repeat offenders, bears that are killed for public safety, are females. This creates a further depressive effect on an already endangered species. The grizzly bear is officially described as "threatened" in the U.S. Though the problem is most significant with regard to grizzlies, these issues affect the other types of brown bears as well.
In Europe, part of the problem lies with shepherds; over the past two centuries, many sheep and goat herders have gradually abandoned the more traditional practice of using dogs to guard flocks, which have concurrently grown larger. Typically, they allow the herds to graze freely over sizeable tracts of land. As bears reclaim parts of their range, they may eat livestock. In some cases, the shepherds shoot the bear, thinking their livelihood is under threat. Many are now better informed about the ample compensation available, and will make a claim when they lose livestock to a bear.
Legal status
The grizzly bear, sometimes called the ''silvertip bear'', is listed as threatened in the contiguous United States. It is slowly repopulating in areas where it was previously extirpated, though it is still vulnerable.
The California golden bear (''Ursus arctos californicus'') disappeared from the state of
California in 1922, when the last one was shot in
Tulare County, but it is still on the state
flag of California. The bear is alluded to in the names of the sports teams of the
University of California, Berkeley (the
California Golden Bears), and of the
University of California, Los Angeles (the
UCLA Bruins) and in the mascot of
University of California, Riverside (Scottie the Bear, dressed in a Highland
kilt).
The Mexican grizzly bear is listed as an endangered species, but it may be extinct.
In Canada, it is listed as vulnerable in Alberta, British Columbia, Northwest Territories, and Yukon Territory. Prairie populations of grizzly bear are listed as extirpated in Alberta, Manitoba, and Saskatchewan.
The brown bear is a European Protected Species, given protection throughout the European Union.
The brown bear is also the national animal of Finland.
The brown bear is depicted on the reverse of the Croatian 5 kuna coin, minted since 1993.
Bear encounters
There are an average of two fatal attacks by bears per year in North America. In
Scandinavia, there are only four known cases since 1902 of bear encounters which have resulted in death. The two most common causes for bear attack are surprise and curiosity. Some types of bears, such as polar bears, are more likely to attack humans when searching for food, while
American black bears are much less likely to attack.
The Alaska Science Center ranks the following as the most likely reasons for bear attacks:
# Surprise
# Curiosity
# Invaded personal space (this includes a mother bear protecting her young)
# Predatory intent
# Hunting wounded
# Carcass defense
# Provoked charge
Aggressive behavior in brown bears is favored by numerous selection variables. Unlike the smaller black bears, adult brown bears are too large to escape danger by climbing trees, so they respond to danger by standing their ground and warding off their attackers. Increased aggressiveness also assists female brown bears in better ensuring the survival of their young to reproductive age. Mothers defending cubs are the most prone to attacking, being responsible for 70% of brown bear-caused human fatalities in North America.
Attacks on humans
As a rule, brown bears seldom attack humans on sight, and usually avoid people. They are, however, unpredictable in temperament, and will attack if they are surprised or feel threatened. Sows with cubs account for the majority of injuries and fatalities in North America.
Habituated or food-conditioned bears can also be dangerous, as their long-term exposure to humans causes them to lose their natural shyness, and, in some cases, to associate humans with food. Small parties of one or two people are more often attacked than large groups, with only one known case of an attack on a group of six or more. In that instance, it is thought that due to surprise the bear may not have recognized the size of the group. In contrast to injuries caused by American black bears, which are usually minor, brown bear attacks tend to result in serious injury and, in some cases, death. In the majority of attacks resulting in injury, brown bears precede the attack with a growl or huffing sound, and seem to confront humans as they would when fighting other bears: they rise up on their hind legs, and attempt to "disarm" their victims by biting and holding on to the lower jaw to avoid being bitten in turn. Due to the bears' enormous physical strength, even a single bite or swipe can be deadly, as in tigers, with some human victims having had their heads completely crushed by a bear bite. Most attacks occur in the months of July, August and September, the time when the number of outdoor recreationalists, such as hikers or hunters, is higher. People who assert their presence through noises tend to be less vulnerable, as they alert bears to their presence. In direct confrontations, people who run are statistically more likely to be attacked than those who stand their ground. Violent encounters with brown bears usually last only a few minutes, though they can be prolonged if the victims fight back.
Attacks on humans are considered extremely rare in the former Soviet Union, though exceptions exist in districts where they are not pursued by hunters. Siberian bears, for example, tend to be much bolder toward humans than their shyer, more persecuted European counterparts. In 2008, a platinum mining compound in the Olyotorsky district of northern Kamchatka was besieged by a group of 30 bears, who killed two guards and prevented workers from leaving their homes. Ten people a year are killed by brown bears in Russia. In Scandinavia, only three fatal attacks were recorded in the 20th century.
In Japan, a large brown bear nicknamed "''Kesagake''" (袈裟懸け, "kesa-style slasher") made history for causing the worst bear attack in Japanese history at Tomamae, Hokkaidō during numerous encounters in December, 1915. It killed seven people (including one pregnant woman) and wounded three others (with possibly another three previous fatalities to its credit) before being gunned down after a large-scale beast-hunt. Today, there is still a shrine at Rokusensawa (六線沢), where the event took place, in memory of the victims of the incident.
Native American tribes sympatric to brown bears often viewed them with a mixture of awe and fear. North American brown bears were so feared by the Natives, they were rarely hunted, especially alone. When Natives hunted grizzlies, the act was done with the same preparation and ceremoniality as intertribal warfare, and was never done except with a company of 4–10 warriors. The tribe members who dealt the killing blow were highly esteemed among their compatriots. Californian Indians actively avoided prime bear habitat, and would not allow their young men to hunt alone, for fear of bear attacks. During the Spanish colonial period, some tribes, instead of hunting grizzlies themselves, would seek aid from European colonists to deal with problem bears. Many authors in the American west wrote of Natives or voyagers with lacerated faces and missing noses or eyes due to attacks from grizzlies. Within Yellowstone National Park, injuries caused by grizzly attacks in developed areas averaged approximately one per year during the 1930s through to the 1950s, though it increased to four per year during the 1960s. They then decreased to one injury every two years during the 1970s. Between 1980 and 2002, there have been only two human injuries caused by grizzly bears in a developed area. Though grizzly attacks were rare in the backcountry before 1970, the number of attacks increased to an average of approximately one per year during the 1970s, 1980s, and 1990s.
History of defense from bears
A study by Canadian and US researchers has found
pepper spray to be more effective at stopping aggressive bear behavior than guns, working in 92% of studied incidents versus 67% for guns. Carrying pepper spray is highly recommended by many authorities when traveling in bear country; however, carrying two means of deterrent, one of which is a large caliber gun, is also advised. Solid shotgun slugs, or three buckshot rounds, or a semiautomatic pistol of .45 caliber or more is suggested if a heavy hunting rifle is not available. Guns remain a viable, last resort option to be used in defense of life from aggressive bears. Too often, people do not carry a proper caliber weapon to neutralize the bear. According to the Alaska Science Center, a
12 gauge shotgun with
slugs has been the most effective weapon. There have been fewer injuries as a result of only carrying lethal loads in the shotgun, as opposed to deterrent rounds. State of Alaska Defense of Life or Property (DLP) laws require one to report the kill to authorities, and salvage the hide, skull, and claws.
Campers are often told to wear bright colored red ribbons and bells, and carry whistles to ward off bears. They are told to look for grizzly scat in camping areas, and be careful to carry the bells and whistles in those areas. Grizzly scat is difficult to differentiate from black bear scat, as diet is in a constant state of flux depending on the availability of seasonal food items. If a bear is killed near camp, the bear's carcass must be adequately disposed of, including entrails and blood, if possible. Failure to move the carcass has often resulted in it attracting other bears and further exacerbating a bad situation. Moving camps immediately is another recommended method.
State of Alaska Department of Natural Resources website states, "Select a gun that will stop a bear (12-gauge shotgun or .300 mag rifle)."
Culture
Many Native American tribes both respected and feared the brown bear, even thinking of it as a god. One tale tells of how the black bear was a creation of the
Great Spirit, while the grizzly was created by the Evil Spirit. In
Kwakiutl mythology, black and brown bears became enemies when Grizzly Bear Woman killed Black Bear Woman for being lazy. Black Bear Woman's children, in turn, killed Grizzly Bear Woman's own cubs.
The grizzly bear is the state animal of both Montana and California.
Brown bears often figure into the literature of Europe and North America, in particular that which is written for children. "The Brown Bear of Norway" is a Scottish fairy tale telling the adventures of a girl who married a prince magically turned into a bear, and who managed to get him back into a human form by the force of her love and after many trials and difficulties. With "Goldilocks and the Three Bears", a story from England, the three bears are usually depicted as brown bears. In German speaking countries, children are often told the fairytale of Snow White and Rose Red; the handsome prince in this tale has been transfigured into a brown bear. In the United States, parents often read their preschool age children the book Brown Bear, Brown Bear, What Do You See? to teach them their colors and how they are associated with different animals.
The Russian bear is a common national personification for Russia (as well as the Soviet Union). The brown bear is also Germany's and Finland's national animal.
The school mascot for Brown University, the University of California, Los Angeles, the University of California, Berkeley, and the University of Alberta is the brown bear.
The coat of arms of Madrid depicts a bear reaching up into a ''madroño'' or strawberry tree (''Arbutus unedo'') to eat some of its fruit, whereas the Swiss city of Bern's coat of arms also depicts a bear and the city's name is popularly thought to derive from the German word for bear.
In the town of Prats de Molló, in Vallespir, Northern Catalonia, a "bear festival" (''festa de l'ós'') is celebrated annually at the beginning of spring, in which the locals dress up as bears, cover themselves with soot or coal and oil, and "attack" the onlookers, attempting to get everyone dirty. The festival ends with the ''ball de l'os'' (bear dance).
