Dear Bill,
This is Helen Ross responding via Lauren Braden's email. I believe that
bird poop is white (actually it's white and brown) because of the
concentration of urea. Rather than defecating and urinating, most
songbirds eliminate both types of waste together. Hope this helps.

Fellow Tweets,
My daughter asked me a question which I cannot answer. Perhaps some of
you
know the explanation;
"Why is bird poop white when the poop of other animals is brown or
black?"
Thanks for the help.
