On
Geoffrey's comment. As do most, if not all, Australian finches, have black on all of the bill, for some
species they stay black, for most it then changes to red or yellow or white or
blue-grey a mix of these. I wonder what would be the story for this bird that
Margaret saw, when it was young. Would it have had an all white beak? Who knows?
I looked in HANZAB for any mention of this abnormality and didn't find
it.

Red-browed Finches have black on the top of the bill. They also have black
on the rest of the bill.

Hi Margaret.
Your first RBF appears to have white on
top of the beak, but almost certainly that is merely a reflection (Philip's
"trick of the light"). But it certainly appears to lack the black patch on top
of the beak (it does show black under the beak).
The second specimen does
appear "normal".

Finch. So I
can't see what you are referring to. To answer your question. Yes all adult Red-browed Finches have
a black stripe down the top of their beak (but no other finch
species does, as far as I know). So if there
is white on the top of its
beak, then
if it is not poo (i.e. uric acid) or a trick of light reflection, it is probably
a genetic defect.
