Churchill problem polar bear report for week 3, July 23-29 2018

Polar bears that have come off the sea ice of Hudson Bay near Churchill, Manitoba in Western Hudson Bay are apparently in a wide variety of conditions, from very fat to skinny.  So, not all skinny despite the relatively early breakup of ice in the northwest.
