[Nhcoll-l] [EXT] how to clean birds nests ?

Wed Sep 14 10:22:26 EDT 2022

Dear Benoit,

This is quite tricky, due to the nests' fragility, as you already pointed
out. My recommendation is to not make a blanket policy that all nests must
be vacuumed/cleaned/dusted, and go on a case-by-case basis. Some nests may
be in good enough condition that you do not need to do anything, and others
may have varying degrees of need. Adding a net will only make sure that all
the fragments you pull with the vacuum remain with the nest and are not
sucked into the vacuum, but will not protect from the damage happening in
the first place.

My recommendation would be to use a triage approach: assess all nests,
separate them into three main categories (ready to move, needs some
cleaning, too far gone, or something of the sort) and then see how many you
have in each category. The ones that are already ready to go, just go, and
the ones that need some cleaning should be addressed on a case-by-case
basis. Finally, those that are too dirty to be useful should be addressed
with a different approach, which is whether it is important to keep them or
not, due to their deteriorated condition. This is a hard question to ask
but if they do not serve any research, exhibit, or educational purpose due
to deterioration, it is a curatorial/collections management question that
needs to be asked prior to any resources put into their cleaning,
especially because this can take a long time and effort from staff.

I'm happy to discuss with you techniques and approaches for cleaning, if
you're interested, so let me know and we can go from there.
Best,
Mariana
