觀察細節

Possible Nashville. When I first spotted it, it came across as a Nashville to me. Complete prominent eye ring, gray head, yellow undertail coverts. But other features then seemed to rule it out, including white upper chest, only yellow on lower flanks/belly. I believe the wings were more grayish than green. Also ruled out Virginia's. However ran Merlin twice and the call came up as Nashville each time. Seen in a small grove of mixed trees with a family of Lazuli Buntings.
