Carpet beetle excrement (frass). If there are feathers, closely examine them
for larvae. If you are certain no larvae are feeding on the feathers, then
proceed as follows: If you can remove the claw, you can safely freeze it to
insure no further damage. Recommended -20 F for 3 days, then allow it to
acclimate to room temperature slowly.

div.yiv7792751521WordSection1 {}-->Hello all, We have a ceremonial wand on
display with an eagle claw in it. This past week we discovered a bit of debris
under a section of it. Some bits are larger and irregularly sized and look
like bits of the claw’s skin/scales that were losses. There is also a very
small yellowish white particulate that has a very regular size and shape to the
particles. We lightly brushed the claw off and more of this fell to the Mylar
we were collecting it on. The claw is still on display after sweeping up the
debris. It seems stable and we don’t see any additional particles loosed from
it or created otherwise over the weekend. Image is attached. We don’t have
a microscope so I did the best I could to capture this. We found no bugs in
the case when we first saw the bits but a day or two later when we went to
remove and examine it we saw a small unidentified black bug and some small
wings in the case. No new debris was found though. These particles are really
small, in the 1/10 millimeter size perhaps. This is outside of my realm of
expertise. If anyone has experience with the preservation of eagle claws and
what may be going on here I’d love your opinion. Is it an insect infestation
(frass)? Is there a preservative issue we need to contend with (could this be
arsenic?!?)? What should I do? It has been stable for days and we are
monitoring it daily now. Any and all help and advice appreciated! Jodi
