My personal opinion is that white-winged juncos, just as in the summer, have
a very circumscribed range. I saw only one in living in Denver for 15
years, one in Cherry Hills for 18 years, and my only one in Centennial (4
years) a month ago. On the other hand, Bill Brockner had them every winter
in Evergreen at his house. They probably could be "mapped out" for winter
range here.
I have an occasional slate-colored junco where the white shows easily...some
birds with no white visible at all...but no confusion with a white-winged.
I also think that white-winged juncos act differently than others...that
would be my first choice for splitting out a species...much as the black
rosy finch behaves differently.

When we lived on Spring Drive, Boulder County we had White-
winged Juncos every winter, sometimes as many a four at once.
As I recall, you used to have Ring-necked Pheasants there, too. And look what good that's done the poor pheasant population in Boulder County!
