<p class="MsoNormal"><span lang="EN-US" style="color:#1F497D">First take a DNA sample and freeze in it -80°C if possible, we store them in little tubes with 80% pure Ethanol. This is the only sure way to preserve the Sample.

<p class="MsoNormal"><span lang="EN-US" style="color:#1F497D">Since Ethanol is no fixative I would definitely recommend fixating in a formaldehyde solution (3%) for 2 days. Important is (like Simon wrote) to inject the fixative in the bird head and stomach
cavities (use natural cavities to avoid destroying tissue, like mouth and anus). These parts tend to rot quickly. Afterward you have to wash the specimen in fresh water for 2 times, at least 3 days of storage in the fresh water for better diffusion. Use the
same Jar in which it will be stored in, to dispose the formaldehyde-water correctly. Afterwards you can transfer into Ethanol in small steps (20-40-60-75%) always for at least 4 days in each step. You can add 5% glycerin to the final solution for better color
preservation (The few good color preservation in old specimens that I’ve seen have Glycerin in it).<o:p></o:p></span></p>

<p class="MsoNormal"><span lang="EN-US" style="color:#1F497D">Colors tend to fade with Ethanol, so there is no sure way to keep the colors for longtime preservation (other than dry).<o:p></o:p></span></p>

<p class="MsoNormal"><span lang="EN-US" style="color:#1F497D">About the Wings, we too store them in Mylar sleeves, but I have seen that they tend to get very flatten and would recommend archival boxes whit a PE Foam sheet on which you can pin the wings with
acid free paper straps. This Tipp was given to me from the Museum in Lausanne, when I asked the same question a few months ago.

<p class="MsoNormal"><span lang="EN-AU">Hi all,<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-AU"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-AU">We have some birds that we would like to preserve whole, in alcohol. We are currently discussing the best way to preserve them – apparently in the past birds here were put directly into 70% EtOH with no exposure to formalin.
I have encountered some pretty squishy birds in spirit, however. On the other side, I recently saw an email from a collection manager suggesting putting birds in 10% formalin for 10 days before transferring them to EtOH, which seems like a very prolonged exposure
to me. If any of you who preserve birds in fluids would share what you all do, I’d really appreciate it!
