Marshall/Fred,
Thanks for posting.
In January 2019, I ran into a crow that was almost completely white except for
markings on the face - it was in a cemetery in Northampton County.
I was able to catch a short video of it:

Following up on Marshall's white wing-patch crows, which I also have seen
here in Oakton a few times, I came across these interesting articles that
you might find useful.

Could be a low protein diet, or genetics, or other factors.
I would guess that protein in the diet might be particularly important as
growing nestlings form and pigment all their feathers simultaneously.
Thanks, Marshall
All the best

In real life, the shortest distance between two points is never a straight
line, so you might as well enjoy the journey !!
