In an update to an earlier story from last month about a male polar bear spotted near Kaktovik with a tight satellite radio collar, a Russian biologist has voiced some some serious criticisms of the use of these devises.
In another news outlet, Andrew Derocher has finally admitted publicly that the Kaktovik bear with the tight collar is a male and is”likely his” (Global News, 23 November 2015; “Is this polar bear really being choked by a research collar?”). The male bear appears to have been fitted with a collar some time between 2007 and 2011. The collar should have fallen off by now but hasn’t. Derocher suggested maybe the collar isn’t really too tight and the blood might not belong to the bear. And that if the bear really wanted the collar off, he “…will be able to remove it himself.”
The criticisms of the use of collars are well worth reading.
