Thanks, Brandon, for the exhortation to pay attention to white-breasted nuthatches. Steve Mlodinow provides a superb review in Birding:

Hi all,Would people going on Colorado CBCs be interested in keeping track of the sub-species of White-breasted Nuthatches on your Colorado CBCs this year? This year you can enter Eastern White-breasted Nuthatch and Interior White-breasted Nuthatch, if you see/hear any on your Christmas Bird Counts (mostly Easterns on found Eastern Plains counts, though it is possible to see them on the Front Range too). It might be nice to report the number of Easterns on Colorado CBCs this year (in-case they get split sometime). The Easterns have pale blue backs and sound like Red-breasted Nuthatches, and the Interior ones have darker blue backs. Compilers who wish, can add Eastern and Interior White-breasted Nuthatches to your list, of course you get both, it only counts as one species.
