Spotted this guy(I'll call it a male) while I was on the phone. After the call, saw that he was still there, grabbed the camera, took this shot to check the settings and then he was gone. Haven't seen him since. Initially thought it was a Red-breasted Nuthatch and then thought of a Brown Creeper, but it's neither of these. But it's about that size w/ bold white eyebrows. Taken 11/1 in north-central Illinois.
Coincidentally, a RBNH showed up today after a long absence.
Anyway, any suggestions, possibilities on an ID here? I'll keep a lookout for a possible return.
