Polar bears can come ashore any time of year and cause trouble: a timely reminder

If you thought polar bears were only a danger to people in summer when sea ice is low, think again. Bears do occasionally come ashore early to mid-winter looking for food because hunting is difficult and they are approaching their leanest time of year. They simply walk from the ice onto land – often close to communities – because many things associated with modern human living are food attractants for polar bears.

This tracking map of Western Hudson Bay bears (females with collars) 11 January 2021 (courtesy Andrew Derocher) shows a bear just offshore near the community of Whale Cove on the northwest coast – close enough to come ashore if she decides that could be in her best interests:

Derocher had this to say about the location of this bear (12 Jan 2021):

It may be ‘odd’ for a bear to be so close to shore in winter but since we know that polar bears do come ashore in winter, it isn’t rare but ‘uncommon’. Most of the trouble with bears ashore seems to come in March/April on the coast of Labrador and Newfoundland when sea ice is more extensive and where 2017 was an exceptional year.

Trouble with bears in January/February:

2019 Labrador, Bears reported onshore in Labrador (January 2)

2019 Labrador, Bears onshore in Labrador causing problems (February 1)

2019 Alaska, Polar bear attack hundreds of miles from shore (January 15)

2016 Labrador, Bears onshore in Labrador (7 February)

Below is a chart from 1985, when sea ice off Labrador and Newfoundland was as thick in mid-January as it was in 2019, yet as far as I know, there were no reports of bears ashore in Labrador or northern Newfoundland. This difference is almost certainly because the population size of Davis Strait bears had not yet recovered from previous centuries of overhunting and harp seals numbers were still quite low compared to what they rose to over the next three decades: currently, both Davis Strait polar bears and harps seals are abundant (DFO 2012, 2014, 2020; Peacock et al. 2013) and numbers could still be climbing, although the results of a recent bear survey in the region has not yet been published.

Not predicted: more sea ice than average in southern-most Arctic first week of August

Polar bear habitat update for the first week of August 2019 shows there is still more sea ice than average in Hudson Bay, the southern-most area of continuous habitation for this species. That certainly wasn’t part of the predictions of doom, especially since freeze-up in that region for the last two years has also been earlier-than-average which means a shorter ice-free season than we’ve seen for decades.

Despite ice coverage for the Arctic ice as a whole being marginally lower than it has been since 1979 for this time of year, sea ice for the first week of August was also above average around Svalbard in the Barents Sea and higher than the last few years in the Central Arctic, which is a critical summer refugium for polar bears that live in the peripheral seas of the Arctic Ocean, including the Chukchi (see photo below, taken in early August 2018).

Polar bear ashore in Puvirnituq NE Hudson Bay over the weekend

More ‘bears on shore’ news today, this time involving a young polar bear that came ashore in the village of Puvirnituq, northern Quebec and was shot for safety reasons by a local hunter.


This incident is reminiscent of one last year a bit further north (Ivujivik) in early March, which I reported here.  Both involved young bears from the large and stable Foxe Basin subpopulation. As I’ve pointed out before, most bears in late winter are at their lowest weight and this can make them very dangerous if they come ashore looking for food.

But unlike the Ivujivik incident, was the first time a bear had ever come into the village of Puvirnituq, making it more like the visit in late February 2017 of a young female bear in Inukjuak further  south along the coast, the first such visit of a polar bear to that community in more than 30 years.

The exception to lean condition in late winter being the norm are bears in the Davis Strait subpopulation that have harp seals to feed on by February and are often in good condition by early March, as was the bear reported ashore yesterday in Newfoundland.

Puvirnituq, northern Quebec. Polar bears in this region are part of the Foxe Basin subpopulation.

The news today came via an English language blog post that got an essential detail wrong1, so I turned to Google Translate to offer this version of the original, in French (Journal de Montreal, 7 March 2018):
