Authorities in the United States on Wednesday have identified a 24-year-old woman and her one-year-old son as the victims of a fatal polar bear attack in an isolated Alaska Native village.
The fatal mauling happened on Tuesday in Wales, a coastal community that is no stranger to co-existing with polar bears, situated along the Bering Strait on the westernmost tip of the North American mainland — about 80km (50 miles) from Russia.
Summer Myomick of Saint Michael and her son, Clyde Ongtowasruk, were killed in the attack, Alaska State Troopers said in a statement.
The polar bear had chased several residents before another community member shot and killed it, authorities said. The attack occurred near a school in Wales.
Poor weather and a lack of runway lights at the Wales gravel airstrip prevented Alaska State Troopers and officials from the Alaska Department of Fish and Game from arriving in Wales on Tuesday after the attack. Attempts were being made again on Wednesday.
When asked to describe the mood in Wales on Wednesday, Dawn Hendrickson, the school’s principal, called it “traumatic”.
Classes were cancelled after the fatal attack. “The students are with their families,” Hendrickson said. Counselors were being made available to students.
Like many far-flung Alaskan villages, the predominantly Inupiaq community of roughly 150 people organises patrols when the bears are expected in town, from July through early November, before the sea ice forms and bears head out on the frozen landscape to hunt seals.
That makes what happened this week almost unheard of because polar bears are normally far out on the ice in the dead of winter and not close to villages, said Geoff York, the senior director of conservation at Polar Bear International, a conversation group. The last fatal polar bear encounter in Alaska was in 1990.
“I would have been walking around the community of Wales probably without any [bear] deterrents because it’s historically the time of year that’s safe,” said York, who has decades of experience studying polar bears. “You don’t expect to run into bears because they’d be out on the sea ice hunting seals and doing their thing.”
It’s unclear if this attack was related to climate change, York said, but it’s consistent with what is expected as the Arctic continues to warm at four times the rate of the rest of the Earth, changing the ecosystem in ways that are still not fully understood.
However, this particular bear is a member of a population that is doing fairly well, said Andrew Derocher, a professor of biological sciences at University of Alberta and an expert on polar bears.
Alaska scientists at the US Geological Survey in 2019 found changes in sea ice habitat had coincided with evidence that polar bears’ use of land was increasing and that the chances of a polar bear encounter had increased.
“We are expecting and have anecdotally seen an uptick in human-polar bear encounters. Fortunately, most of those don’t end in injury or death, but the probability of that happening seems to be on the rise,” York said.
Wales is just over 161km (100 miles) northwest of Nome. The community is accessible by plane and boat, including barges that deliver household goods. Winter trails provide access on snowmobiles to other communities and to subsistence hunting grounds. All-terrain vehicles or ATVs are used for non-winter hunting and fishing trips.
Polar bears are at the top of the food chain and see humans as a food source, York said.
A report he co-authored titled “Understanding Polar Bear Attacks”, detailing fatal polar bear encounters, found that most involved either sub-adult bears — usually males who are hungry all the time — or older bears who are injured or ill and having difficulty getting enough calories.
“Both of those bear types are more likely to take risks, like we saw here in Wales,” York said.
Unlike brown or black bears, polar bears do not hibernate in the winter. Only pregnant females enter snow dens, and that’s only for reproduction.
All the other polar bears are out, typically on sea ice where their prey is available year-round.
The Alaska Nannut Co-Management Council, which was created to represent “the collective Alaska Native voice in polar bear co-management”, said on its website that polar bears near or entering villages represent ongoing safety concerns for communities.
The group notes a few polar bear patrol programmes in Alaska, including one for Wales, which it said was seeking funding to maintain operations. Another, in the Native village of Diomede, operates a patrol mainly in the winter to protect kids walking to and from school.
York — who has worked in the Arctic for about 30 years, 21 of which were spent in Alaska — said the community of Wales has long been involved in establishing a polar bear patrol programme and taking measures to keep polar bears out of the community.
“This seems to be just one of those terrible cases where, despite doing the right things, we had a bear that was an outlier at a time of year that you would never expect that to happen,” he said.
Derocher, the professor of biological sciences at the University of Alberta, said the location of the attack is far south in the distribution of polar bears, but it isn’t abnormal for them to be there.
The polar bear is from a population in the Chukchi Sea that is faring well amid climate change, Derocher said. That means the attack could be the result of the bear being lured by attractants such as food or garbage more than by climate change factors, he said.
The polar bears near the southern Beaufort Sea, east of the Chukchi Sea population, are in worse shape, Derocher said.
In this case, even though there is ice in the Chukchi and northern Bering seas, the quality of the ice is not well known. More importantly, York said, it’s unknown what is going on under the ice or what the availability of seals and other prey is for polar bears.
The changes are also happening in the winter, when people assumed they were safe from polar bears being on shore, said York.
“Communities may no longer be,” he said.
