RCMP on manhunt spot a fat polar bear far from the coast of Western Hudson Bay

In the course of a manhunt for two murder suspects wanted in British Columbia, Royal Canadian Mounted Police posted a photo of a fat polar bear they spotted about 200 km north of Gillam, Manitoba.

This fat bear – as would any others that might be spotted in the area – is a pregnant female from the Western Hudson Bay subpopulation intent on finding a secure place to dig a den in the permafrost where she can stay cool over the summer and give birth this winter.

However, true to form, The Guardian (28 July 2019) ludicrously suggests those on the hunt for the murder suspects are now at risk of a polar bear attack:

The threat of a polar bear attack has become a reality for the huge Canadian police and military contingent searching for the teenage duo suspected of shooting dead Australian tourist Lucas Fowler, his US girlfriend and a university botanist.

Location of Gillam, Manitoba below. The bear was sighted as being “about 200 km north of Gillam” which I figure should be about as far north as the label for Wapusk National Park on this Google map (Google tells me it’s 118 km from Gillam to Herchmer):

As far as I know, there is not a single record of a well-fed pregnant female attacking a human before she enters her maternity den in the summer (Wilder et al. 2017). Even the fatal attack in Foxe Basin last August, which was perhaps the first known attack made by a well-fed adult female, involved a bear with a cub to feed. I discuss this incident in depth in my new book, The Polar Bear Catastrophe That Never Happened.

What is surprising about this sighting is the possible evidence of Western Hudson Bay polar bear denning west of known denning areas in Wapusk National Park and along the Manitoba/Ontario coast (Clark and Stirling 1997; Clark et al. 1997; Scott and Stirling 2002; Yee et al. 2017). Depending on the exact location the bear was seen (whether inside or outside the park, not specified by the original RCMP tweet), this sighting has possible implications for population estimates based on aerial surveys that stop their searches at the park boundary (Crockford 2019a, b; Dyck et al. 2017; Lunn et al. 2016; Stapleton et al. 2014).
