Hi Robert,
They could certainly be of either race. Both occur here, and currently I have a few of both races at my feeders daily here in Teller County at 8,500'. The white-winged is a noticeably larger junco and a very light gray. If you get good looks, they can be distinguished by having one more white tail feather (r4) on each side of the tail than the other races. Giving the distinct look of more white in the tail. Best seen on take-off or if they happen to spread their tail while feeding. The Slate-colored group (I believe only the hyemalis subspecies will have the occasional wing bars), is a smaller, darker-gray junco; and again with one-less white tail feather (r4 being dark) on each side, giving the impression of a darker overall tail. With that said, I have certainly seen individuals with significant wing-bars that I would not definitely put in either race; and I leave them as "unknown as to race". I hope this helps. Let me if you get any pics.

Does anyone know if they were likely that race or what Sibley describes as the "rare" Slate-colored with white wing bars. We were unable to compare body or bill size with the others as they kept separate and our camera battery died so no pics. Other birds seen were 1 female Evening Grosbeak a resting (appeared sickly) BC and MT Chickadees a flitting , 7 Steller's Jays a pushing, 5 Pygmy Nuthatches a hopping, Downy and Hairy Woodpeckers a drumming (male and female of both species), and one Magpie and House Finch each, sorry no Partridge.
