A cougar (aka puma/mountain lion) was captured in downtown Victoria yesterday (my home town), with all the drama given a polar bear attack. No polar bear alert program here, just cougar tracking hounds on standby and officers with guns and tranquilizer darts.
The Globe and Mail has video here.
Details and quotes below. CBC story was the only one to include a map, which I have put into polar bear perspective.
Due to the atypical pattern of sea ice melt on Hudson Bay this year, 2015 will definitely be a later than average breakup year – perhaps not as late as 1992 but maybe almost as late as 2009. Easing into the first days of Arctic summer, there is still a lot of polar bear habitat left on Hudson Bay, especially in the east.
Although official breakup in 2009 was only a little later than usual (9 July), bears came ashore about the same time (after mid-August) as they did in 1992, when breakup was very late (30 July). With the pattern this year being so unusual (and the melt so slow over the last few weeks), who knows how late it could be before the last bears leave the ice in 2015?
There is definitely more sea ice this year on the bay than there was last year, when breakup was about average for the last 24 years.
UPDATE 2 July 2015: CIS weekly ice coverage graphs added to the end of this post. Hudson Bay ice highest since 2009 and Davis Strait highest since 1994! Have a look.

This is a short discussion about research on polar bear penis bones, regarding a new paper that sent several of the Internet’s most juvenile science headline writers off the deep end.1
Short quiz first. Above are the penis bones (each called a baculum, plural bacula) of three marine mammals – one is from a bearded seal, one from a polar bear and another from a Steller sea lion. Which one do you think is the polar bear? Answer below.
This is not a bet or prophesy based on models, it’s my conviction as an experienced zoologist, based on history demonstrating the resilience of the species.
I’m so sure about Western Hudson Bay polar bears that I’ve started a spare-change jar marked “Send Nico to Churchill.” Nico is my new grandson, just two months old now. This will be our first Christmas with a baby in a long time.
Nico’s special savings account will assure that in 20 years (given wise investments), he’ll be able to see Churchill polar bears in their own element.
Warmest wishes to all my readers and thanks for your support, it is much appreciated.
Apparently, some biologists think that outputs from complex computer models will convince native Arctic residents that invasive mark-recapture work has no long-term effect on the health and well-being of polar bears.

The Victoria blizzard of 1996 (Dec. 28-29) dropped 124 centimetres (48.8 inches) of snow. Not too far off some recent accumulations around Buffalo and other western New York State communities (great photos here). Just wacky weather (and nothing to do with polar bears) but memorable if you’ve lived through it and the stories out of NY have twigged my memories.
We get a maritime version of “lake-effect” snow here in Victoria (which is on Vancouver Island), where cold air moves offshore from the Interior of the province, travels over the relatively warm Strait of Georgia (see map below) and dumps snow on south island communities. Victoria is renowned for mild winters but when these cold conditions all line up just right, Victoria might as well be Buffalo.
Snow at the front door, original here, taken 28 December 1996 in Victoria, B.C.
I didn’t have a camera then, which is a pity, but others did. Someone downtown (where accumulations were somewhat less than 48 inches) made a video, copied below. A diversion from polar bear shenanigans that you might find of interest.
