Here's one for ya:

It seems that pigeons, a bird of very little brain, have taken to roosting
on the exhaust stack for the perchloric acid hood in the plant sciences
building.  They sometimes roost on other stacks but they seem to prefer the
perchloric hood.  This is a dedicated exhaust for the hood and when the
hood is washed down, well, you can guess what ends up splattered into the
fume "cupboard."

Do I need to worry about potentially explosive pigeon guano?  Should we
have users washdown the hood before use as well as after?  What about
exposure to pigeon diseases?  I don't think there's anything I can do to
discourage roosting but I'm open to those ideas, too.

Thanks for your help,
Debbie
