Posted onAugust 31, 2022|Comments Off on Video: Fat polar bears on the shore of Hudson Bay near Churchill, one catches a goose
This little snack won’t make much difference to the bear’s survival but rare film footage of an already-fat bear (estimated at 1,000lbs) catching and eating a Canada goose on Friday last week (26 August 2022) just outside of Churchill on the western shore of Hudson Bay is not a bear motivated by starvation to eat something other than seals.
Newsreel of the goose hunt is below; photo of another fat bear, also near Churchill, taken the day before (25 August 2022) is shown above, see more from that day here.
Meanwhile, no further reports from Churchill about problem bears: the last one issued was for the first week in August. Time will tell at freeze-up whether this will be yet another very good year for Western Hudson Bay bears.
Polar bear specialist Andrew Derocher reported that two of his 23 tagged polar bears were still on the sea ice, a phenomenon that’s been happening since at least 2015 at breakup. Instead of heading to shore when the sea ice concentration dwindles below 50% coverage, some bears are choosing to lounge around on decaying bits of ice, sometimes into late July or well into August, until they must finally swim ashore. There is no evidence that the bears continue to successfully hunt seals under these conditions but no evidence either that their choice to stay on the ice rather than move to land at this time of year has had any negative impact on their health or survival.
Funny how these reports in recent years (these included) don’t mention the condition of bears the way they used to as recently as 2017 (or the state of the sea ice). I guess it’s so they can’t be used as evidence against the prevailing mantra that western Hudson Bay polar bears that spend the summer onshore are starving because of the lack of ice due to human-caused global warming!
Posted onJuly 29, 2022|Comments Off on Most Hudson Bay polar bears are still offshore, excellent ice conditions for late July
With only a few days until the end of July, most Western Hudson Bay polar bears are still on a thick band of thick first year ice that remains close to shore. The few bears that have come off the ice appear to be nice and fat, indicating they had good spring feeding conditions.
We’ll have to wait a few more weeks to see if this year shapes up as it did in 2020, when the last of bears didn’t come ashore until the third week of August, despite there being very little visible ice. Last year, most of the bears were ashore by the end of July.
Posted onJuly 26, 2022|Comments Off on Expert admits polar bears in Svalbard are thriving despite the greatest loss of sea ice in the Arctic
In an article published last week, polar bear specialist Jon Aars is quoted as saying that Svalbard bears are “unexpectedly” thriving. However, he fails short of admitting that the bears don’t really need summer ice as long as they are well-fed in spring, which they have been for the last two decades—this year included.
The suggestion by Aars that the Svalbard archipelago could one day be ice-free for the entire year is speculative hyperbole but even if that were to happen, it would only mean the permanent movement of 300 or so Svalbard bears to Franz Josef Land (still within the Barents Sea) where ice conditions are less volatile.
Posted onJuly 19, 2022|Comments Off on Some of the first polar bears onshore in Western Hudson Bay are in excellent condition
From the live cams installed on beluga tour boats running near the Churchill River, we have some good photos of a few fat polar bears onshore in Western Hudson Bay.
These bears were attracted to the remnants of a beluga carcass with nothing much left on it (lower right in the photo) and stayed around for at least a few days. The female with her cub-of-the-year was remarkably tolerant of an adult male nearby.
Posted onJuly 14, 2022|Comments Off on Arctic sea ice still quite abundant for early summer
Despite rhetoric to the contrary, there is still plenty of sea ice over Arctic regions this summer, supplying feeding platforms for polar bears, ice-dependent seals, and walrus cows nursing their young calves. Forget about whether the numbers are below or above some short-term average, there is no catastrophe in the making for marine mammals in the Arctic at this time.
Remember, by early summer, young seals have left the surface of the ice and are in the water feeding; predator-savvy adults and subadults are hauled out on broken chunks of ice moulting their hair-coat. They may look like sitting ducks but polar bears have a hard time catching them because the seals are vigilant and have many escape routes available (due to all the open water). Most polar bears in Hudson Bay are still on the ice (you’ll see why below): the live cams near Churchill set up to watch polar bears are presently showing images of ravens with sea ice in the background, not bears.
This post is predominantly sea ice charts for mid-July, what we in the science field call observational evidence, aka ‘facts’. Keep in mind that satellites used to produce these images have an especially hard time distinguishing ice topped with melt water from open water, which means much more ice useful to these marine mammals is almost certainly present than is shown in the charts (as much as 20% more in some regions).
