So, I guess they didn’t all die because of lack of sea ice in the Chukchi Sea. I said back on 28 August, just after the some unauthorized photos were publicized, that this haulout looked just as large as last year’s, if not larger (walruses are occasional prey of polar bears).
Now confirmed by an official US Fish and Wildlife Service estimate of 35,000 – not 36,000 mind you, or 34,000 – it was definitely 35,000. Odd, that. And surprisingly, they didn’t bother going out to count them until the day President Obama came to town. Would FWS have even bothered to get a count if there hadn’t been something newsworthy to tie it to?
Even more strange is the fact that this year, there was no accompanying hype. There were no links in any of the stories to FWS or USGS propaganda website pages, like there were last year (nor even a link to a press release). No mention of the FWS plan to have walruses declared ‘threatened with extinction‘ because of global warming. And no mention of prosecution of the photographer who took the photos on 23 August, from the required distance, but without a permit. Note the permit number stamped on the official NOAA photo provided below (taken 2 September 2015), which few outlets carried, probably because it looks nothing like a photo of walruses on a beach:
It appears that this year 35,000 walruses on a beach is a non-story. Go figure. Excerpts from the one, widely-circulated story below, from three days ago. See previous post for more walrus background, map, and video.

Now we have poor hunting conditions in the Bering Strait touted as evidence that “walrus migration patterns have changed” with the implication that this is because “…the past eight years have had the eight lowest amounts of summer sea ice on record” due to man-made global warming.
A subsistence lifestyle is hard, particularly so if it depends on a highly mobile, migratory herd animal. Think Barren-ground Inuit caribou hunters, who often starved because herd sizes declined for a few years or moved unpredictably.
Many factors – seasonal weather, last year’s winter conditions, size of the herd, food supply – all affect where and when a migratory herd will move and the likelihood it will be positioned for optimal harvesting by hunters. Add another highly variable factor into that – Bering Sea ice – and you have a highly unpredictable food supply, especially if you sit in one spot (like on St. Lawrence Island) and expect that migratory herd animal to come within reach.
Hunting walrus from St. Lawrence Island depends on just the right combination of ice and winds. Too much ice is not good, too much open water is not good, and too much wind is not good.
Alaska Dispatch, courtesy the Associated Press, reports St. Lawrence natives are again short of walrus meat because of “warm temperatures”: “Warming temps push walrus north, leaving Alaska villages without traditional food source” (Rachel D’Oro, The Associated Press, August 6, 2015). And the caption of the above USGS (A. Sonsthagen) photo predictably implies all current hunting troubles can be blamed on climate channge:
“The walruses in this July 2012 file photo are hauled out in the Eastern Chukchi Sea. Walrus migration patterns have changed as sea ice and other environmental factors have shifted — and that’s spelled trouble for Alaska Native communities who hunt them for subsistence.”
The people of St. Lawrence Island and the Bering Strait that depend on walrus for subsistence have my sympathy, they indeed have a hard life – but this is not a tale of woe about the status of Pacific walrus and changing summer sea ice.
Bering Strait natives hunt walrus in spring, from mid-April to early June (Huntington et al. 2013). All indications are that walrus are moving differently than they used to in summer because the population is now very large. As far as I know, there is no new population information on walrus that wasn’t available last year, when I covered this topic extensively (Crockford 2014; video below).
