In a remote corner of British Columbia, Canada, a subspecies of the North American black bear known as the Kermode bear, or spirit bear, exhibits a rare genetic trait that gives it a striking white fur coat.
These unique bears, characterized by a recessive gene mutation, are colloquially referred to as spirit bears and are found primarily on certain islands within this region.
Renowned wildlife photographer Jenny Stevens recently had a remarkable opportunity to capture these elusive creatures on camera, a feat she had eagerly anticipated for years.
Stevens positioned herself in an area where Kermode bears frequent during the salmon hunting season, a crucial period before they enter hibernation.
“The spirit bear population totals no more than 400 individuals,” Stevens remarked, highlighting the rarity of witnessing these animals in their natural habitat.
Unlike albino animals, spirit bears retain pigmentation in their eyes and skin due to a single mutant gene that disrupts melanin production while maintaining overall health.
The prevalence of this gene allows for the occasional birth of a white Kermode bear from two black Kermode bear parents through positive assortative mating.
Recent studies have shown that spirit bears, with their hidden appearance, have a significant advantage in catching salmon during daylight hours compared to their black counterparts.
This adaptation contributes to their survival and dietary habits as omnivores, allowing them to thrive even when salmon are not readily available.
Local traditions and scientific interests have substantially driven the conservation efforts for spirit bears.
Trophy hunting of all bears in the Great Bear Rainforest has been banned, and legal victories by First Nations communities have prevented environmental threats such as oil pipelines that could jeopardize the bears’ habitats.
