Why are the Spirit Bears born white?
Named after Frank Kermode, former director of the Royal B.C. Museum, Victoria. The Kermode or Spirit Bear is a black bear that has white fur due to a rare genetic trait. The bear is not albino, as it typically has a brown nose and eyes.
Are Kermode bears Leucistic?
The Kermode bear, also known as the 'spirit bear', is a subspecies of bear found in British Columbia, Canada. While the subspecies itself isn't purely white, it is best known for its large leucistic population. In some parts of their range, up to 20% of the Kermode bear population is leucistic.
Why are some bears white?
Polar bears have white fur so that they can camouflage into their environment. Their coat is so well camouflaged in Arctic environments that it can sometimes pass as a snow drift. Interestingly, the polar bear's coat has no white pigment; in fact, a polar bear's skin is black and its hairs are hollow.
Are Spirit Bears just albino?
Is a spirit bear just an albino bear? No, spirit bears are not albino. They have pigment in their skin and eyes, which wouldn't be the case with albinos. Spirit bears have a single mutant gene that causes their unusual colouration.
What is the rarest bear type?

Which bear is the rarest?
The spirit bear, also known as the Kermode bear, is the rarest bear in the world and a subspecies of the black bear found only in this small part of British Columbia.
Do spirit bears change color?
Spirit bears are the rarest color phase of all black bears. Black bears can change colors throughout their lives. Most commonly, young bears in brown or cinnamon phases will get darker (black) as they reach adulthood. Bears also molt in summertime, changing the appearance of their fur to a lighter sheen.
Is the Spirit Bear genetically unique?
Their striking colour is caused by an uncommon recessive genetic trait. Spirit bears are not a unique species or subspecies, but a unique colouration of the coastal British Columbian black bear subspecies kermodei.
What does a white Spirit Bear symbolize?
White spirit bear The White fur of Spirit Bear symbolizes peace, purity, strength, endurance and determination. It signifies fearlessness in your pursuits and confidence to achieve anything you desire.
What is the difference between leucistic and Piebald?
Commonly, instead of being entirely white, a leucistic animal may have irregular patches of white among its normal coloring. This partial leucism is known as a “piebald” effect. A leucistic rock pigeon shows off an example of piebald feathers. Leucism can be caused by injury, poor nutrition, or a genetic imbalance.
What is the difference between leucistic and albino?
Because albinism affects all melanin production in an animal's cells, this means that partial albinism cannot exist. This phenomenon is known as leucism, the partial loss of all types of pigmentation, including carotenoids. Leucism causes white coloration, white patches, spots, or splotches on the skin or fur.
Can humans be leucistic?
Therefore, leucistic phenotypes can be associated with defects, which mainly impair sensory organs and nerves. In humans, a well-known example is the Waardenburg syndrome.
What is Ghost bear?
GhostBear makes your encrypted data less detectable to governments, businesses, and ISPs. It does this by making VPN traffic less detectable on your network, making it harder to block. GhostBear is currently available on our Windows, macOS, and Android apps.
Can a black bear be white?
Black bears come in more colors than any other North American mammal. They can be black, brown, cinnamon, blond, blue-gray, or white.
How rare is a white bear?
Between 10-20% of the population has white fur. Sometimes people call them Spirit Bears.

One tale, told by the Kitasoo/Xai'Xais Nation, says that as the sheets of ice began to retreat, Raven—the creator of all things—made the animal known as the spirit bear to remind him of the ice and snow.
Why do they call it a spirit bear?
Due to a recessive gene, 20% of the Kermode bear population in North America are born with white fur. These bears are often termed to look ghostly in the dense rainforest due to their white fur. As a result, they have named spirit bears (or the White Kermode) as a tribute to their ghostly white fur.
How rare is a white bear?
Between 10-20% of the population has white fur. Sometimes people call them Spirit Bears.
What is the most common bear color?
blackMost of them are black, but in some areas up to 20% are creamy white and called Spirit Bears. Farther north, another subspecies, the Glacier Bear (Ursus americanus emmonsii), lives in southeastern Alaska. Again, most are black, but a few are dark bluish gray with silver-tipped guard hairs.
How rare are white grizzly bears?
White grizzlies are almost unheard of. Polar bears roam the Arctic, and the West Coast has Kermode, or spirit, bears — though they're a variant of black bear, and their numbers are estimated to be in the low hundreds.
Can a grizzly bear be white?
Nicknamed Nakoda, Parks Canada has given this white grizzly bear the official designation of GBF178, or Bear 178.
What is a Kermode bear?
The Kermode bear is a subspecies of the black bear that lives in British Columbia. Around ten to thirty percent of Kermode bears are white or cream instead of black. The percentage depends on the location. The pale and sometimes ghostly appearance of the animals has given rise to the alternate names spirit bear and ghost bear.
Why is the Kermode bear capitalized?
The term "Kermode bear" refers to the whole subspecies, so it includes both the black and the white animals. It's often used for only the white animals, however.
What animal has white hair?
If the animal has two recessive alleles, it will have white hair. A bear gets one allele for hair colour from its mother and the other from its father. If it gets an allele for white hair from both of its parents, it will be a spirit bear. The allele for white hair is less common than the one for black hair.
How long do bears live?
They reach reproductive maturity at three to four years of age. The bears sometimes live for as long as twenty-five years. The winter period of inactivity in bears is usually known as torpor or a winter sleep instead of hibernation. Some biologists refer to bears as "super hibernators".
How many bears are there in the Great Bear Rainforest?
The size of the spirit bear population in the Great Bear Rainforest is unknown. Estimates are generally in the range of 100 to 300 animals. It's unknown whether the population is increasing, decreasing, or staying the same.
Why is the spirit bear important?
The beautiful spirit bear is important in the culture and history of the local indigenous people and is the official mammal of British Columbia. For me, it symbolizes the impressive rainforest on the north and central coast of the province. This habitat is known as the Great Bear Rainforest. Its size gives it global importance.
Why do bears have light hair?
Genetic Cause of Light Hair in the Bear. Spirit bears have white or cream fur but dark eyes and a dark nose, so they aren't albinos. Their colouration is caused by a different method from albinism. Genes exist in the form of alleles, or gene variants. Alleles are paired and are either dominant or recessive.
What caused the Kermode gene to rise?
The gene probably rose to prominence during the last Ice Age, Ritland says. Glaciers then covered the Northwest, cutting off a bear population on a glacier-free strip of northern coastline where inbreeding would have helped increase the frequency of the Kermode gene. Lowered sea levels extended the coast over the continental shelf. When the ice retreated and sea levels rose, many bears were isolated on coastal islands.
Why are white bears more efficient than black bears?
Researchers have discovered that white bears are twice as efficient as black in catching salmon, because in the water, the white bears are less visible to the evasive fish.
Why are Kermode bears so vulnerable?
Kermode bears may be uniquely vulnerable to oil spills, biologists fear. Studies show that coastal bears den surprisingly close to the sea and emerge in mid-winter to feed on shore creatures. In addition, the steep coastline often forces bears to travel along the water’s edge.
What is the Kermode bear?

What is the Kermode ecosystem?
The Kermode stands out as an icon for a rare and endangered ecosystem. British Columbia’s coast represents the world’s last large, intact temperate rainforest. It is home to an abundance of eagles, ospreys and grizzlies. All five species of Pacific salmon spawn in its streams.
Is a Kermode bear a black bear?
The Kermode bear is not a distinct species of black bear but a subspecies with a high fre quency of a unique mutation in a pigmentation gene. Population geneticist Kermit Ritland, of the University of British Columbia, led the study that identified the mutation, which involves the same gene that produces the blonde coat of golden retrievers. Most of the island’s black-coated bears carry this recessive Kermode gene. Two are needed—one from each parent—to produce a spirit bear.

How many bears are there in the Great Bear Rainforest?
But “no one really knows how many bears there are in the Great Bear Rainforest,” cautions Chris Darimont, the Hakai-Raincoast professor of geography at the University of Victoria, who is partnering with the Kitasoo/Xai’xais and other First Nations, including the Heiltsuk, down the coast, in the first on-the-ground research incorporating indigenous knowledge and customs in the study of the rainforest’s bears.
Why is the color of snow in the book Raven?
One of the kids is the color of snow because of a deal that Raven, a trickster and Creator of everything, had made with the black bears long ago. After turning himself into a child to learn how to make fire, Raven, then white, flew out through a hut’s smoke hole, singeing his wings and covering them with soot.
Where do white bears live?
The largest concentration of white bears, an estimated 7 out of a population of 35, inhabits 80-square-mile Gribbell Island, in the territory of the Gitga’at, the next nation up the coast. The greatest number, maybe 50 or 60, is on Princess Royal Island, adjacent to Gribbell and ten times larger. And there are frequent sightings around Terrace, on the mainland to the north. In 2014, guides at the Spirit Bear Lodge, in Klemtu, saw eight, the most since the lodge had opened six years earlier.
