Should have been Carolina. I have seen a couple of Black-Capped (admittedly based on song and apparent size) over the last couple of years. The Red-breasted Nuthatches are in great quantities this year and very early so it may be a good year for the Black-capped chickadees, too. I also realize that I left out 23 Goldfinch in my listing.
