Here's another view of the "mystery" bird.
Yes, you are all very sharp and perceptive! It IS indeed a yellow-rumped warbler in fall plumage, taken last fall in southeastern Ohio. The bird was snagging insects on a warm morning from the railing of our deck.
I guess it was a bit of a curveball to show a fall warbler instead of a spring/breeding-plumage bird.
