Latest sea ice maps and charts from the Canadian Ice Service show significant ice building quickly along the west coast of Hudson Bay, enough to allow polar bears out to hunt.
Kelsey Eliasson reported from Churchill earlier today that most of the polar bears have moved onto the ice.
In contrast, vocally alarmist biologist Andrew Derocher tweeted on the evening of Saturday, 15 November:
“Our satellite collared bears still onshore in w. Hudson Bay – 1 a bit offshore. Waiting for sea ice: getting late.“
I reminded him that Hudson Bay freeze-up is not truly “late” unless it is delayed until the first week in December (as it was in 1983). I won’t dispute the fact that his collared bears appear to be mostly onshore in this track map but remember these are all females with satellite collars.
The behaviour of collared females, many of which may have cubs, does not necessarily represent the movements of the entire population and it is really misleading to suggest that they do. There is definitely ice present along the coast — these females are not “waiting for ice.” More misinformation.
As Kelsey has pointed out, mothers with cubs have been noticeably lagging a bit behind the rest of the bears moving out onto the ice, perhaps to give the big males a wide berth:
From what I can see, I would peg freezeup as November 13th this year, a couple days early but pretty much right on time. There were a couple more days of bears but mostly they were mother and cubs emerging from the willows and heading straight out on the bay. Its always a bit surprising at just how many bears sit the season out, hunkered down just inland until the last days of the season.
With these families appearing, it really sums up at just what a productive season this has been for the western Hudson Bay population. Any guide who knows their stuff will tell you this was a banner year for cubs, one we haven’t seen in a long time. With this early freezeup and hopefully a later breakup next spring, this could really restore the balance to this population and quell the death knells heard in the media. Or maybe not. We’ll see.
Conservation even started releasing bears early this year, with their first releases to the ice starting on the 14th and continuing over the next few days. Almost all the bears just trucked out on the ice, one or two made a quick loop back to land but seal hunting conditions are prime right now so there’s not much draw to keep them here. [my bold]
