THE SPIRIT BEARS OF CANADA'S WEST COAST

Mist clings to the moss-draped cedars, and the river below churns with the silver flash of salmon fighting upstream. 

Then, out of the shadows, a pale figure steps onto the slick stones—a spirit bear, its coat glowing against the emerald forest like a ghost made flesh. 

Each movement is unhurried, deliberate, as if the forest itself pauses to watch. Water beads and slides down its fur, its great head lifting to catch the scent of fish on the wind. 

In that moment, the rainforest hushes—ravens fall silent, even the river seems to soften—leaving only the sound of your breath and the soft trickle of a nearby stream as you realize you are witnessing something few people on Earth ever see.

On the temperate rainforests of British Columbia’s central and north coast, a rare white-furred black bear (Ursus americanus kermodei) roams among towering cedars, moss-draped hemlocks, and salmon-rich rivers. 

Known scientifically as the Kermode bear but more commonly called the spirit bear, this unique subspecies of the American black bear holds both biological and cultural significance. Their pale coats, the result of a genetic variation, have captured global fascination while remaining deeply rooted in the traditions of local First Nations peoples.

Spirit bears are not albinos; rather, their distinctive white coat results from a recessive allele in the melanocortin 1 receptor (MC1R) gene. 

To display the white fur, an individual must inherit the allele from both parents. Roughly 10–20% of the Kermode bear population in some regions are white-coated, though overall only about 1 in 10 black bears in the subspecies carries this trait. The remainder are typically black-furred, indistinguishable from other American black bears at a glance.

Spirit bears inhabit the Great Bear Rainforest, one of the largest remaining intact temperate rainforests in the world, stretching along British Columbia’s remote central and northern coast. 

They are most frequently found on Princess Royal Island and Gribbell Island, as well as smaller portions of the surrounding mainland. These regions offer a rich mosaic of old-growth conifer forests, rivers teeming with salmon, and sheltered estuaries that provide food and cover.

Like other black bears, spirit bears are omnivorous generalists. Their diet changes seasonally:
  • Spring: young vegetation, grasses, sedges, and roots.
  • Summer: berries (salmonberries, huckleberries, blueberries), insects, and carrion.
  • Autumn: spawning Pacific salmon (Oncorhynchus spp.), which form the most critical food source for building fat reserves before winter denning. Salmon runs sustain the bears and also fertilize the forest. Bears often carry fish into the understory, leaving behind nutrients that enrich soil and feed trees, mosses, and invertebrates—a classic example of nutrient cycling.
Spirit bears are generally solitary, though feeding grounds such as salmon streams may bring multiple individuals together. Unlike coastal grizzlies, they tend to avoid confrontations, relying on patience and stealth while fishing. Interestingly, recent research suggests that spirit bears may enjoy a fishing advantage: their pale coats are less visible to salmon in bright daylight, allowing them to capture fish more efficiently than darker bears.

In late autumn, spirit bears retreat to winter dens, often dug into hollow logs, root systems, or natural rock shelters. They enter a state of torpor rather than true hibernation, slowing their metabolism while occasionally rousing during warmer spells. Cubs are born during this denning period, usually in January, and remain with their mothers for 1.5–2.5 years.

For millennia, the white bear has held deep spiritual and cultural meaning for First Nations peoples of the Pacific Northwest, including the Gitga’at, Kitasoo/Xai’xais, and Heiltsuk Nations. 

Known as moksgm’ol among the Gitga’at, the spirit bear is revered as a reminder of the Ice Age, when the land was blanketed in snow and ice. Oral traditions tell that Raven made one in every ten bears white to remind people of the time when glaciers ruled the earth, teaching humility and respect for nature.

Today, First Nations guardians continue to play a central role in protecting spirit bear habitats, leading stewardship programs, guiding visitors, and sharing cultural teachings. Their leadership was instrumental in the establishment of conservation agreements that limit industrial development and preserve the Great Bear Rainforest.

Though not classified as endangered, spirit bears are vulnerable due to their limited genetic distribution and reliance on intact rainforest ecosystems. Logging, habitat fragmentation, and declining salmon populations pose risks. The protection of their habitat through the 2016 Great Bear Rainforest Agreement and ongoing Indigenous stewardship has been critical in ensuring their survival.

Viewing Spirit Bears — Because of their rarity and remote habitat, spirit bears are challenging but not impossible to see in the wild. Some of the best-known viewing opportunities include:
  • Princess Royal Island – the largest concentration of spirit bears.
  • Gribbell Island – often called the “mother island” of the white bear.
  • Kitasoo/Xai’xais territory near Klemtu – guided spirit bear tours led by Indigenous stewards.
Tourism is strictly managed to reduce disturbance and ensure that viewing supports conservation and local communities.

The spirit bear is a striking example of how biology and culture intertwine. Its unique genetics, ecological role in the rainforest, and place in Indigenous oral traditions make it an emblem of both natural wonder and cultural heritage. 

Protecting the spirit bear means safeguarding the Great Bear Rainforest itself—a living system where salmon, cedar, eagle, wolf, and bear are inseparably linked.
