An oil spill in the Arctic would most likely concentrate in the areas where polar bears and their prey are also concentrated, such as sea ice leads. [2] Because polar bears rely partly on their fur for insulation and soiling of the fur by oil reduces its insulative value, oil spills put bears at risk of dying from hypothermia. The study did not determine if the others lost their cubs before, during, or some time after their long swims. [184] It banned all importing of polar bear trophies. Top 10 Biggest Bears on EarthToday, the bears can be very large.But this cannot be compared with their prehistoric relatives.A prehistoric South American gi. Its hearing is about as acute as that of a human, and its vision is also good at long distances. A. Baker, M. E. Obbard, and B. Malloch, eds.). Winnen and his friends actually spotted the massive bear in . [204], Polar bears diverged from brown bears 400,000600,000 years ago and have survived past periods of climate fluctuation. It is known, for example, that already in the winter of 1784/1785 Russian Pomors on Spitsbergen harvested 150 polar bears in Magdalenefjorden. [66], Compared with its closest relative, the brown bear, the polar bear has a more elongated body build and a longer skull and nose. [42] These alternatives may reduce the rate of weight loss of bears when on land. Its massive forest acreage, also the biggest on Earth, is crucial for keeping carbon out of the atmosphere. It is the largest extant bear species, as well as the largest extant land carnivore. Only one case of a polar bear with rabies has been documented, even though polar bears frequently interact with Arctic foxes, which often carry rabies. [130] On average, each litter has two cubs. When you think of a polar bear, you think of thick, white fur. [179] Other provisions included year-round protection of cubs and mothers, restrictions on weapons used and various administrative requirements to catalogue kills. That's right, standing on its hind legs, this massive bear was the same height as an African elephant. 900 bears a year were harvested in the 1920s and after World War II, there were as many as 400500 harvested annually. Several such sites have been preserved on the Yamal Peninsula. Their concentrations in polar bear tissues continued to rise for decades after being banned, as these chemicals spread through the food chain. [82] Satiated polar bears rarely attack humans unless severely provoked. [51], The polar bear is a marine mammal because it spends many months of the year at sea. The largest bear species in the world include polar bears, brown bears, and spectacled bears. White King, the world's largest polar bear, is on display in the coffee shop of Elko's Commercial Hotel and Casino. [97] However, in the short term, some polar bear populations in historically colder regions of the Arctic may temporarily benefit from a milder climate, as multiyear ice that is too thick for seals to create breathing holes is replaced by thinner annual ice. The polar bear's claws are short and stocky compared to those of the brown bear, perhaps to serve the former's need to grip heavy prey and ice. 3. [61] Adult females are roughly half the size of males and normally weigh 150250kg (330550lb), measuring 1.82.4 metres (5ft 11in 7ft 10in) in length. The largest polar bear in the world was a whopping 2,209 pounds! [165] The treaty was ratified in October 2007. [34] As the distance increases between the pack ice and the coast, females must swim longer distances to reach favoured denning areas on land. The polar bear is one of the largest of its kind, with the adult male weighing between 772 and 1,543 pounds. Seals migrate in response to these changes, and polar bears must follow their prey. [48], Modern methods of tracking polar bear populations have been implemented only since the mid-1980s, and are expensive to perform consistently over a large area. [161] The numbers taken grew rapidly in the 1960s, peaking around 1968 with a global total of 1,250 bears that year. [145] Adult polar bears are occasionally vulnerable to predation by orcas (Orcinus orca) while swimming, but they are rarely reported as taken and bears are likely to avoid entering the water if possible if they detect an orca pod in the area. [citation needed] Environment Canada also banned the export from Canada of fur, claws, skulls and other products from polar bears harvested in Baffin Bay as of 1 January 2010. [33] Polar bears can breed with brown bears to produce fertile grizzlypolar bear hybrids;[5][34] rather than indicating that they have only recently diverged, the new evidence suggests more frequent mating has continued over a longer period of time, and thus the two bears remain genetically similar. The shoulder height of an adult polar bear is 122 to 160cm (4ft 0in to 5ft 3in). They are powerful enough to take down enormous prey. This subpopulation feeds heavily on ringed seals in late spring, when newly weaned and easily hunted seal pups are abundant. [125] Polar bears have a generally polygynous mating system; recent genetic testing of mothers and cubs, however, has uncovered cases of litters in which cubs have different fathers. At up to 2,000kg (4,400lb) and a typical adult mass range of 600 to 1,500kg (1,300 to 3,300lb), a walrus can be more than twice the bear's weight,[107] has extremely thick skin and has up to 1-metre (3ft)-long ivory tusks that can be used as formidable weapons. [97], The polar bear's most common hunting method is called still-hunting:[98] the bear uses its excellent sense of smell to locate a seal breathing hole, and crouches nearby in silence for a seal to appear. A bear is a fur-covered mammal which is generally monogamous, territorial, and lives in solitary. Due to their position at the top of the ecological pyramid, with a diet heavy in blubber in which halocarbons concentrate, their bodies are among the most contaminated of Arctic mammals. ", "Ecological risk assessment of persistent organic pollutants in the arctic", "Chlorinated hydrocarbon contaminants and metabolites in polar bears (, "Rebuttal of "Polar Bear Population Forecasts: A Public-Policy Forecasting Audit", "The Energetic Value of Land-Based Foods in Western Hudson Bay and Their Potential to Alleviate Energy Deficits of Starving Adult Male Polar Bears", "Can polar bears use terrestrial foods to offset lost ice-based hunting opportunities? [224], Coca-Cola has used images of the polar bear in its advertising,[225] and Polar Beverages, Nelvana, Bundaberg Rum, Klondike bars, and Fox's Glacier Mints all feature polar bears in their logos. [125] This was the case for 40% of cubs there in the early 1980s; however by the 1990s, fewer than 20% of cubs were weaned this young. It stood an impressive 11 feet 1 inch tall when on its hind legs. Given this tall frame, you would expect such a large animal to weigh thousands of pounds. In some areas, the polar bear's diet is supplemented by walrus calves and by the carcasses of dead adult walruses or whales, whose blubber is readily devoured even when rotten. Prior to the early 1970s, this species suffered significant unsustainable hunting. [135] The proportion of maternity dens on sea ice has changed from 62% between the years 1985 through 1994, to 37% over the years 1998 through 2004. [202][203] The bears could disappear from Europe, Asia, and Alaska, and be depleted from the Canadian Arctic Archipelago and areas off the northern Greenland coast. PCBs have received the most study, and they have been associated with birth defects and immune system deficiency. Polar bears were chased from snowmobiles, icebreakers, and airplanes, the latter practice described in a 1965 New York Times editorial as being "about as sporting as machine gunning a cow. [41] Canada has allowed sport hunters accompanied by local guides and dog-sled teams since 1970,[171] but the practice was not common until the 1980s. [196] In recent years, polar bears in the Arctic have undertaken longer than usual swims to find prey, possibly resulting in four recorded drownings in the unusually large ice pack regression of 2005. Most people are familiar with polar bears from visiting zoos or seeing the bear depicted in the media, but there are many misconceptions about this fascinating animal. [125], When the ice floes are at their minimum in the fall, ending the possibility of hunting, each pregnant female digs a maternity den consisting of a narrow entrance tunnel leading to one to three chambers. He has specialized in the study of polar bears since 1990, and has been conducting research in the Arctic since 1977 . In the den, she enters a dormant state similar to hibernation. Did you know? [97], Problematic interactions between polar bears and humans, such as foraging by bears in garbage dumps, have historically been more prevalent in years when ice-floe breakup occurred early and local polar bears were relatively thin. [26] Further, some clades of brown bear, as assessed by their mtDNA, were thought to be more closely related to polar bears than to other brown bears,[28] meaning that the brown bear might not be considered a species under some species concepts, but paraphyletic. [107][113] The dump in Churchill, Manitoba was closed in 2006 to protect bears, and waste is now recycled or transported to Thompson, Manitoba. Polar bears are champion travelers. It weighed 2,209 lbs. Females communicate with their young with moans and chuffs, and the distress calls of both cubs and subadults consists of bleats. The Kodiak is a subspecies of the brown bear native to Alaska. [75], The polar bear has an extremely well developed sense of smell, being able to detect seals nearly 1.6km (1mi) away and buried under 1m (3ft) of snow. Nevertheless, polar bears are listed as "Vulnerable" under criterion A3c, which indicates an expected population decrease of 30% over the next three generations (~34.5 years) due to "decline in area of occupancy, extent of occurrence and/or quality of habitat". [175], Due to warming air temperatures, ice-floe breakup in western Hudson Bay is currently occurring three weeks earlier than it did 30 years ago, reducing the duration of the polar bear feeding season. [178], In Greenland, hunting restrictions were first introduced in 1994 and expanded by executive order in 2005. Canada began imposing hunting quotas in 1968. [181], Polar bears are currently listed as "Rare", of "Uncertain Status", or "Rehabilitated and rehabilitating" in the Red Data Book of Russia, depending on population. polar bear Geographic ranges of living species of bears [54][111] Current estimates put the global population at between 20,000 and 25,000[45] or 22,000 and 31,000. The polar bear is among the most sexually dimorphic of mammals, surpassed only by the pinnipeds. [138] Polar bears are especially susceptible to Trichinella, a parasitic roundworm they contract through cannibalism,[139] although infections are usually not fatal. [45] Until 2005 Greenland placed no limit on hunting by indigenous people. This specimen, when mounted, stood 3.39 m (11 ft 1 in) tall on its hindlegs. [88] Polar bears are usually quiet but do communicate with various sounds and vocalizations. An estimated 3,500 bears live on Kodiak, which gives it a population density of 0.7 bears per square mile. U.m. However, polar bears tend to. [98], A widespread legend tells that polar bears cover their black noses with their paws when hunting. With the average man weighing 200 pounds, this bear was the size of 11 grown men! tall. A multi-year (2008 . Scientists have responded by noting that hungry bears may be congregating around human settlements, leading to the illusion that populations are higher than they actually are. [94] Studies have also photographed polar bears scaling near-vertical cliffs, to eat birds' chicks and eggs. [40], The International Union for Conservation of Nature, Arctic Climate Impact Assessment, United States Geological Survey and many leading polar bear biologists have expressed grave concerns about the impact of climate change, with some predicting extinction by 2100. On 15 May 2008, the United States Department of the Interior listed the polar bear as a threatened species under the Endangered Species Act, citing the melting of Arctic sea ice as the primary threat to the polar bear. In their southern range, especially near Hudson Bay and James Bay, Canadian polar bears endure all summer without sea ice to hunt from. Read more They exhibit sexual dimorphism, where male polar bears can be two to three times larger than female polar bears. These were traded in the villages of the lower Yenisei and Khatanga rivers to the forest-dwelling peoples further south, who would sew them into their hats as protection against brown bears. The United States began regulating hunting in 1971 and adopted the Marine Mammal Protection Act in 1972. The largest species of bear, polar bears, generally weigh twice or even over five times as much as the Floridian black bear which weighs about 300 pounds. Ferguson, S. H., Higdon, J. W., & Westdal, K. H. (2012). Majestic creature of the far north, the polar bear is the world's largest terrestrial carnivore. Yet, polar bears will very seldom attack full-grown adult walruses, with the largest male walrus probably invulnerable unless otherwise injured or incapacitated. [94] A third hunting method is to raid the birth lairs that female seals create in the snow. [131], Female polar bears have been known to adopt other cubs. [13] It is sometimes referred to as the "nanook", based on the Inuit term nanuq. Due to the absence of human development in its remote habitat, it retains more of its original range than any other extant carnivore. [210], There are several reasons for the apparent discordance between past and projected population trends: estimates from the 1950s and 1960s were based on stories from explorers and hunters rather than on scientific surveys. This polar bear was spotted in Kotzebue Sound, Alaska in 1960. [135] In most areas, cubs are weaned at two and a half years of age, when the mother chases them away or abandons them. [156] Only the liver was not used, as its high concentration of vitamin A is poisonous. Males usually reach sexual maturity at six years; however, as competition for females is fierce, many do not breed until the age of eight or ten. The Alaska polar bear population is estimated to be between 4,000 and 7,000 individuals. Mr Fitzgerald nabbed the bear in September but on Friday it was declared the largest ever killed by a hunter. Weight: Polar bears are the largest land predators alive in the world today (Lynch 1993, p 58). It is a close call, but the polar bear is generally considered the largest bear species on Earth. The melting sea ice in the Arctic may be causing an increase of orcas in the Arctic sea, which may increase the risk of predation on polar bears but also may benefit the bears by providing more whale carcasses that they can scavenge. The biggest surprise in our research has been the degree to which the nutritional requirements of polar bears has not changed from that of their closest ancestor, the grizzly bear. [36] This distinction has since been invalidated. [97] The evolutionary pressure of polar bear predation on seals probably accounts for some significant differences between Arctic and Antarctic seals. The whales are of similar size to the walrus and nearly as difficult for the bear to subdue. 24% had eaten moss recently, 19% had consumed grass, 34% had eaten black crowberry and about half had consumed willows. [156], Their distinctive appearance and their association with the Arctic have made polar bears popular icons, especially in those areas where they are native. The largest polar bear weighed as much as 1,002 kilograms (2,209 pounds), twice the weight of male bears living today. [144] Wolves are rarely encountered by polar bears, though there are two records of Arctic wolf (Canis lupus arctos) packs killing polar bear cubs. Their scientific name means "maritime bear" and derives from this fact. Third, the recent effects of climate change have affected sea ice abundance in different areas to varying degrees. After spending 13 years studying the arctic fox, Dr. Ovsyanikov shifted his focus to the world's largest land carnivore. In unusually warm conditions, the hollow tubes provide an excellent home for algae. The bear was able to reach the truck and tore one of the doors off the truck before Hoshino was able to drive off. Risks to the polar bear include climate change, pollution in the form of toxic contaminants, conflicts with shipping, oil and gas exploration and development, and human-bear interactions including harvesting and possible stresses from recreational polar-bear watching. [70] Polar bears gradually moult from May to August,[71] but, unlike other Arctic mammals, they do not shed their coat for a darker shade to provide camouflage in summer conditions. They will even attack adult walruses when their diving holes have frozen over or intercept them before they can get back to the diving hole in the ice. The length of these swims ranged from most of a day to ten days. Yet, they have often been seen playing together for hours at a time and even sleeping in an embrace,[85] and polar bear zoologist Nikita Ovsianikov has described adult males as having "well-developed friendships. Thus, now the Alaskan population more resembles the world population in that it is more likely to den on land. [211][212][213][214] Second, controls of harvesting were introduced that allowed this previously overhunted species to recover. [205] However, most polar bear biologists think that polar bears will be unable to completely offset the loss of calorie-rich seal blubber with terrestrial foods, and that they will be outcompeted by brown bears in this terrestrial niche, ultimately leading to a population decline. Arturo, the polar bear, has acquired the title of the saddest animal. When kept in captivity in warm, humid conditions, the fur may turn a pale shade of green due to algae growing inside the guard hairs. Please help update this article to reflect recent events or newly available information. the Chukchi Sea currently supports the largest subpopulation in the Arctic (Crockford 2022b). When the ice melts, and the polar bear is in the surroundings of a grizzly bear, the grizzly bear has sufficient advantages to battle with the Polar bear, so grizzly is the winner . [133][134] As of 2006, in Alaska, 42% of cubs were reaching 12 months of age, down from 65% in 1991. [2][41][42], With the discovery of a southeast Greenland population in 2022,[43][44] there are 20 generally recognized, discrete subpopulations of polar bears. [40] The largest polar bear on record, reportedly weighing 1,002 kg (2,209 lb), was a male shot at Kotzebue Sound in northwestern Alaska in 1960. [17] In the Chukotko-Kamchatkan languages of Alyutor and Koryak, the name of the polar bear is umqa, while in the related Chukchi, it is umq. [97] Insufficient nourishment leads to lower reproductive rates in adult females and lower survival rates in cubs and juvenile bears, in addition to poorer body condition in bears of all ages. List of We Bare Bears characters Ice Bear, International Agreement on the Conservation of Polar Bears, Convention on International Trade in Endangered Species, Ministry of Natural Resources and Environment, International Union for Conservation of Nature, 2019 mass invasion of Russian polar bears, "Late Pleistocene fossil find in Svalbard: the oldest remains of a polar bear (, 10.2305/IUCN.UK.2015-4.RLTS.T22823A14871490.en, "Alaska, Chukotka sign agreement to manage polar bears", "Education: Marine Mammal Information: Polar Bears", The fourth world: the heritage of the Arctic and its destruction, "Unequal Rates of Y Chromosome Gene Divergence during Speciation of the Family Ursidae", "Molecular distance and divergence time in carnivores and primates", "Complete mitochondrial genome of a Pleistocene jawbone unveils the origin of polar bear", "Ancient Hybridization and an Irish Origin for the Modern Polar Bear Matriline", "Nuclear Genomic Sequences Reveal that Polar Bears Are an Old and Distinct Bear Lineage", "Population Genomics Reveal Recent Speciation and Rapid Evolutionary Adaptation in Polar Bears", "Brown bears and polar bears split up, but continued coupling", "List of Marine Mammal Species & Subspecies", "Genetic structure of the world's polar bear populations", "Glacial ice supports a distinct and undocumented polar bear subpopulation persisting in late 21st-century sea-ice conditions", "Will These Be the Last Polar Bears on Earth? [148][149] A rather unlikely killer of a grown polar bear has reportedly included a wolverine (Gulo gulo), anecdotally reported to have suffocated a bear in a zoo with a bite to the throat during a conflict. [85] Many attacks by brown bears are the result of surprising the animal, which is not the case with the polar bear. The largest polar bear ever taken, according to Guinness, was shot in Alaska in 1960. In the wild, old polar bears eventually become too weak to catch food, and gradually starve to death. [182] In 2010, the Ministry of Natural Resources and Environment published a strategy for polar bear conservation in Russia. The world's heaviest polar bear weighed an astounding 2,209 pounds. [123] One scientist found that 71% of the Hudson Bay bears had fed on seaweed (marine algae) and that about half were feeding on birds[102] such as the dovekie and sea ducks, especially the long-tailed duck (53%) and common eider, by swimming underwater to catch them. [60] The polar bear is among the most sexually dimorphic of mammals, surpassed only by the pinnipeds such as elephant seals. Male polar bears are much larger than the females. Polar bears are 8-10 ft (2.4-3 m) long. This behaviour, if it happens, is rare although the story exists in the oral history of northern peoples and in accounts by early Arctic explorers, there is no record of an eyewitness account of the behaviour in recent decades. [79], Brown bears tend to dominate polar bears in disputes over carcasses,[143] and dead polar bear cubs have been found in brown bear dens. In October 2019, the Polar Bear Specialist Group of the International Union for the Conservation of Nature (IUCN) released a new assessment of polar bears. [152][153], Polar bears have long provided important raw materials for Arctic peoples, including the Inuit, Yupik, Chukchi, Nenets, Russian Pomors and others. The permit process required that the bear be taken from an area with quotas based on sound management principles. Unlike brown and black bears, polar bears are capable of fasting for up to several months during late summer and early fall, when they cannot hunt for seals because the sea is unfrozen. [172] The guiding of sport hunters provides meaningful employment and an important source of income for northern communities in which economic opportunities are few. The Largest Known Bear, Arctotherium angustidens, from the Early Pleistocene Pampean Region of Argentina: With a Discussion of Size and Diet Trends in Bears Journal of Paleontology, 85 (1), 69-75 . (0.8% in the 1970s, 7.1% in the 1980s, and 14.6% in the 1990s)[172] Nunavut polar bear biologist, Mitchell Taylor, who was formerly responsible for polar bear conservation in the territory, has insisted that bear numbers are being sustained under current hunting limits. A female polar bear ventures close to a visiting boat over the moving ice floe in North Spitsbergen, Norway, 2012. [201], Oil and gas development in polar bear habitat can affect the bears in a variety of ways. The bear may lie in wait for several hours. This polar bear was spotted in Kotzebue Sound, Alaska in 1960. This report may well be dubious, however. Multiple cases of adoption of wild cubs have been confirmed by genetic testing. The polar bear faces a number of threats to its survival, primarily climate change and human influences. (Image credit: Lev Fedoseyev/Contributor via Getty Images) Polar bears ( Ursus maritimus) are the largest bear species and the biggest . [89] Chemical communication can also be important: bears leave behind their scent in their tracks which allow individuals to keep track of one another in the vast Arctic wilderness. [175] Between 1987 and 2004, the Western Hudson Bay population declined by 22%,[194] although the population was listed as "stable" as of 2017. Importing products made from polar bears had been prohibited from 1972 to 1994 under the Marine Mammal Protection Act, and restricted between 1994 and 2008. Males range from about. Although stereotyped as being voraciously aggressive, they are normally cautious in confrontations, and often choose to escape rather than fight. [46], The usual range includes the territory of five nations: Denmark (Greenland), Norway (Svalbard), Russia, the United States (Alaska) and Canada. [51] As the climate change melts sea ice, the U.S. Geological Survey projects that two-thirds of polar bears will disappear by 2050. [106] Polar bears have also been seen to prey on beluga whales (Delphinapterus leucas)[102] and narwhals (Monodon monoceros),[102] by swiping at them at breathing holes. [126] Partners stay together and mate repeatedly for an entire week; the mating ritual induces ovulation in the female. [219] Vehicle licence plates in the Northwest Territories in Canada are in the shape of a polar bear, as was the case in Nunavut until 2012; these now display polar bear artwork instead. The Polar bear - also known as Ursus maritimus - is the largest terrestrial carnivore, whereas the Grizzly bear - the North American brown bear - is the second largest terrestrial flesh-eating mammal. Male polar bears generally weigh between 770 to 1500 pounds (Stirling and Guravich 1990, p 23) but can exceed more than 1500 lbs. 1. Polar bears are one of the most mobile four-legged animals, if not the most. [180], The Soviet Union banned the harvest of polar bears in 1956; however, poaching continued, and is estimated to pose a serious threat to the polar bear population. While the algae is harmless to the bears, it is often a worry to the zoos housing them, and affected animals are sometimes washed in a salt solution, or mild. Most are omnivores except the polar bear which feeds on seals. [83][84] However, due to their lack of prior human interaction, hungry polar bears are extremely unpredictable, fearless towards people and are known to kill and sometimes eat humans. [200], Many chemicals, such as PCBs and DDT, have been internationally banned due to the recognition of their harm on the environment. This is the largest polar bear ever recorded. The existence of the latter has never been confirmed but a massive bear skull uncovered on an Alaskan beach might be the proof that scientists need. This status was re-evaluated and confirmed in April 1999, November 2002, and April 2008. [citation needed]. Size and Weight. 1987. The only bear that comes close is the . During the same time periods, DDT was found to be notably lower in the Western Hudson Bay population only. The typical height for males is between 7 feet, 10 inches, and 9 feet, 10 inches, with . [127], After mating, the fertilized egg remains in a suspended state until August or September. His plight came to the attention of animal lovers a few years ago after he was pictured living in unfit conditions. The family remains in the den until mid-February to mid-April, with the mother maintaining her fast while nursing her cubs on a fat-rich milk. (2011). and stood 10 ft., 4 in. [57], Annual ice contains areas of water that appear and disappear throughout the year as the weather changes. [167], The species is listed in Appendix II of the Convention on International Trade in Endangered Species (CITES) meaning international trade, including in parts or derivatives, is controlled by the CITES system of permits and certificates. [19] In Quebec, the polar bear is referred to by the french terms ours blanc ('white bear') or ours polaire ('polar bear'). [215][216] Many Inuit believe the polar bear population is increasing, and restrictions on commercial sport-hunting are likely to lead to a loss of income to their communities. [185] Since 1994, hundreds of sport-hunted polar bear trophies have been imported into the U.S.[186] In 2015, the U.S. [14], Constantine John Phipps was the first to describe the polar bear as a distinct species in 1774 in his report about his 1773 expedition towards the North Pole. These presumably swam from Greenland, about 300 kilometres (190mi). [111][159] However, since polar bear fur has always played a marginal commercial role, data on the historical harvest is fragmentary. When the seal exhales, the bear smells its breath, reaches into the hole with a forepaw, and drags it out onto the ice. Only with the passage of the treaty did they begin to recover. [35], When the polar bear was originally documented, two subspecies were identified: the American polar bear (Ursus maritimus maritimus) by Constantine J. Phipps in 1774, and the Siberian polar bear (Ursus maritimus marinus) by Peter Simon Pallas in 1776. Kodiak supports some of the largest land-based carnivores in the world, a unique bear population that has been genetically isolated for 12,000 years. [102] Adult male bearded seals, at 350 to 500kg (770 to 1,100lb) are too large for a female bear to overtake, and so are potential prey only for mature male bears. Research of injury patterns in polar bear forelimbs found injuries to the right forelimb to be more frequent than those to the left, suggesting, perhaps, right-handedness. Polar bears are one of the largest land carnivores. What was the largest bear in history? Government of Nunavut officials announced that the polar bear quota for the Baffin Bay region would be gradually reduced from 105 per year to 65 by 2013. [117], When stalking land animals, such as muskox, reindeer,[116] and even willow ptarmigan (Lagopus lagopus), polar bears appear to make use of vegetative cover and wind direction to bring them as close to their prey as possible before attacking. Researchers do not know whether or not this is a new behaviour; before polar ice shrinkage, they opined that there was probably neither the need nor opportunity to swim such long distances.
