I saw some White-breasted Nuthatches over the weekend in the foothills of Jefferson County. This got me wondering about sub-specific identification. Sibley has three groups in his guide. The two I am wondering about are what he calls "Interior West" and "Eastern." Does anyone know if somewhere online (or in a book), there is a good photographic comparison of these groups? The residents in this state would be Interior West birds, but it might be possible to get Easterns here during the winter. As these groups may eventually be split to species level, it would be something good to be keeping track of. I can't find good photos where the subspecies is clearly known.
