I had a female Nashville Warbler at my nut feeder on Thursday morning. 
She was not present this morning. I have a few very blurry pics of it (blurry 
due to taking pics through a window, the curse of autofocus, and low light), 
but I did get very good looks through binocs at it.
Yellowbook shows only a single dot for this month for that species.
