White wings occurs off and on in captive bred finches. It almost always moults
out after the first moult and is assumed to be some dietary deficiency.
However, in some finches pied mutations have arisen as well and this usually
occurs first in the wings.
The ravens wings look extensively white and this makes diet less likely to be
the reason. It may be a mutation.
