Steve, Great job, and thank you for sharing these great photos. Helps us all think harder. I'm not too familiar with Pine W. in fall from my time East (e.g., eye-ring articulation not too pronounced). Thus, a couple details here make me think Blackpoll. Definitely not Orange-crowned or Tennessee from tail length, undertail coverts, and some other structural things. Great job! Thank you for sharing all your hard work with us birders!
