from the dust or other contamination - the undersides of feathers, beneath wings, etc. I would think that in the case of birds that had gotten sooty in their lifetimes, the soot would be more likely evenly distributed throughout the specimen’s feathers.<o:p></o:p></span></p>

<p class="MsoNormal">I have to admit that when I first saw the sooty specimens pictured in the NY Times Article they reminded me of mounted specimens I’d seen many times before, in instances where the birds had been mounted and around 1900 and in at least some
cases exhibited in museums that would have had coal heat. However, I don’t recall noticing study skins coming out of storage that were this sooty.

<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif">I mentioned in my post regarding the historic taxidermy case last week that some of the specimens inside appear sooty. One person replied that it may be caused by mercuric
chloride (applied as a preservative during preparation). A couple other people suggested it may be the result of coal dust in the air at their storage location(s) due to coal heating, rather than soot collected from its habitat in life. The study linked below
is suggesting the latter. I’m curious how they determined the difference between these two carbon contaminants.
