Comparing Churchill problem bear statistics over a few years provides some critical perspective: this year, the bears are causing much fewer problems.
This 2nd week in September is no exception, being the 9th week ashore in all cases: 2017 (4-10 September, where I think “total number of polar bear occurrence reports to date” should be 64, not 53, see week 7 report here), 2016 (5-11 September), 2015 (7-13 September), where there were about 1/2 the number of bears in “jail” this year compared to the last two years (i. e., 6 vs. 11 and 12) and slightly more than 1/2 the number of occurrence reports in 2017 than in 2016 and 2015 (64 vs. 107 and 99):
Now that all bears are ashore for the season, the folks at the Polar Bear Alert program in Churchill note in their report for week 7 (21-27 August, 2017) that the bears ashore are in excellent condition (confirming reports on the first bears ashore in July):
Rather marked contrast to the pessimistic spin on conditions from the field a few months ago:
[yes, a few bears fail to make it through the winter, especially young bears; but that has always been the case — it’s not a sign of human-caused global warming catastrophe]
Last week’s problem bear report also confirmed news from the Churchill Polar Bears website a few weeks ago that showed several images of very fat bears:
See below for last year’s report for week 7 and this year’s report for week 8 (28 August-3 September). Western Hudson Bay polar bears that come ashore near Churchill, Manitoba are starting their third month on land this week, out of the five months or so they have spent ashore in recent years (about 3 weeks more than in the 1980s, no longer than they did in 2004 — conditions have not been getting worse).

Churchill, Manitoba’s Polar Bear Alert Program is still reporting many fewer problems with polar bears onshore than it did last year at the same point in the ice-free season (week 5, 7-13 August):
Compare to week five last year (2016), when bears came ashore in excellent condition:
Although it’s been warmer than average recently (25.4 degrees C yesterday, expected to reach 29 degrees C today and 28 degrees C tomorrow), according to Environment Canada weather records, that’s not even close to an August record-breaker temperature for Churchill. Continue reading

Just out from the City of Churchill: few polar bears reported onshore for the week of 17-23 July 2017 (week 2) but those seen “appear to be in great shape.”
Update 24 July 2017 12:20 PM: Just spotted this blog report from “Churchill Polar Bears” that I somehow missed last week, which includes what seems to be the first polar bear photo’s of the season (of a sow and two chubby cubs) that are also in fine condition.
The photos were taken by Churchill photographer and guide Alex De Vries on Thursday 13 July and I hope he doesn’t mind my including one of those here as documentary evidence of the good body condition of this mother and both her cubs — see more photos at the Churchill Polar Bears blog post dated 14 July here.
Compare last week’s PB Alert report above to last year’s (below):
Today, polar bear biologist Andrew Derocher posted a progress report via twitter on the annual journey ashore of the Western Hudson Bay bears tagged by his University of Alberta research team that shows virtually all of the bears are still out on the sea ice.
After months of gloomy reports on the state of the Hudson Bay sea ice, it’s clear from the map Derocher posted (below) that only one bear out of 12 still transmitting has come ashore so far, although he comments that “some tags haven’t reported lately” (the purple icons are ear tags put on males &/or young bears while the blue icons are collars put on adult females):
Oddly, the same comment was made almost a month ago about these same bears and the suggestion was made that these animals “may be swimming to shore”:
Money quote: Today Derocher remarked that “bears may be shifting behaviour to stay out on less ice” to explain why the tagged bears have still not come ashore as he expects them to do.
Perhaps if he used a different ice chart, it might make more sense (see below). However, the same thing has been happening year after year: WHB polar bears stay on the ice much longer than Derocher predicts but he does not change his expectations or the type of ice chart he uses to track the bears.
As I’ve pointed out before (because this is what field researchers have stated), polar bears have a tough time catching seals after about mid-June or so but they may still prefer to be on the sea ice than on land, even if it’s low concentration ice.
Amid reports that ice conditions between Newfoundland and southern Labrador are the worst in living memory, another polar bear was reported ashore in the area — just after biologist Andrew Derocher explained to the CBC that bears only come on land when sea ice conditions “fail.”
“Ice too thick for coast guard’s heavy icebreaker” said a 20 April 2017 CBC report on the state of ice in the Strait of Belle Isle. The pack is thick first year ice (four feet thick or more in places) and embedded with icebergs of much older, thicker ice. The ice packed along the northern shore of Newfoundland is hampering fishermen from getting out to sea and is not expected to clear until mid-May.
NASA Worldview shows the extent of the pack ice over northwest Newfoundland and southern Labrador on 19 April 2017 (the Strait of Belle Isle is the bit between the two):
The same day that the above satellite image was taken (19 April), at the north end of the Strait on the Newfoundland side, a polar bear was spotted in a small community northwest of St. Anthony (marked below, “Wildberry Country Lodge” at Parker’s Brook). It’s on the shore of north-facing Pistolet Bay on the Great Northern Peninsula, near the 1000 year old Viking occupation site of L’Anse aux Meadows.
There were no photos of the Parker’s Brook bear but lots of others have been taken this year of almost a dozen seen along Newfoundland shorelines since early March: see my recently updated post, with an updated map of reported sightings. Harp seals are now abundant in the pack ice of southern Davis Strait, providing polar bears with an ample source of food when they need it most and therefore, a strong attractant to the area.
Yet, as I reported yesterday, polar bear specialist Andrew Derocher told the CBC this week that polar bears are almost always “forced” ashore by poor ice conditions. The CBC report included his tweet from 10 April, where he suggested “failed” Newfoundland ice conditions were the cause of multiple bears onshore in Newfoundland this year.
Similar thick ice conditions off northern Newfoundland (perhaps even worse) occurred in 2007, see Twillingate in the spring of 2007 below:
Yet, in 2007 there was not a single polar bear reported onshore in Newfoundland (as far as I am aware) but this year there were almost a dozen. And the photos taken this year show fat, healthy bears – not animals struggling to survive.

Apparently, some locals were upset that a polar bear that refused to be scared away from a Newfoundland community over the weekend was shot as it advanced on conservation officers and a crowd of onlookers who refused to disperse (see updated report here on recent Newfoundland polar bear sightings, with annotated map).
“Polar bear shot by wildlife officers near Catalina after being deemed public safety risk” (CBC 10 April 2017)
What these animal lovers may not realize is that Newfoundland in March and April is not a Churchill-like situation: polar bears are in strong hunting mode right now.
Polar bears in late winter and spring have an immense drive to kill and eat as much as possible. Even bears that look well fed will continue to kill and eat. Enticing smells attract them onshore as they investigate any food possibility (see list below).
Seriously, you don’t want that food possibility to be you.
Polar bears can go from watching to charging, in the blink of an eye. You can’t outrun one. Killing quickly is what they do and they are immensely strong. Polar bears generally go for a killing bite to the head. Things to think about when a polar bear is prowling your community…
