<p class="MsoNormal"><span style="font-size:11.0pt"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt">I found the following message by Simon Moore posted back in 2019 responding to Tonya Haff’s question about the best way to preserve birds in spirit. I would like to preserve some bird specimens in alcohol
(after fixing them in 10% formalin) and am interested in using this method to preserve color of feathers. Has anyone tried this method before or since this message was posted? Are there any issues with this method of preservation?<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt">I also saw that adding glycerine in alcohol alone can help preserve the color. I am curious if anyone has done that as well.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt">I would really appreciate any help.<o:p></o:p></span></p>

<p class="MsoNormal" style="background:white"><span style="font-size:10.0pt;font-family:"Courier New";color:black">There was an ornithologist called Serventy from Australia who formulated a special fluid for preserving colour in bird feathers:

<p class="MsoNormal" style="background:white"><span style="font-size:10.0pt;font-family:"Courier New";color:black">Given the formalin present, this would likely serve as a fixative and preservative, although, for a fresh specimen, an immersion in 10% formalin
(and injecting it into the body cavities) for a few days (not as much as 10, that may compromise DNA) will benefit its long term preservation.<o:p></o:p></span></p>
<p class="MsoNormal" style="background:white"><span style="font-size:10.0pt;font-family:"Courier New";color:black">Bear in mind that Serventy’s fluid appeared when molecular biology was in its infancy and not a preservation issue.<o:p></o:p></span></p>
