Hi Jodi,
Did you see any direct damage to the talon? Small holes or something scratches? 
  Also, what other materials are in the wand, or in the case?  Can you send a 
photo of the small bug?  That will help in identifying what is going on and a 
possible treatment.

Good. Luck

Jodi -

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.

Subject: [PestList] FW: eagle claw damage

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!
