I think your call was correct - probably a fall female or immature.

Subject: [VTBIRD] Nashville Warbler question
A smattering of warblers at Emerald Lake State Park in East Dorset today were feeding in the berry bushes west of the parking lot. I identified one as a Nashville Warbler. I had close up views of it's white undertail/belly. However, Sibley's and two other references show bright yellow from breast to undertail. Perhaps the fall Nashville or first year bird has the white? Other markings were the grey head, white eye ring and bright yellow breast.Comments are welcome! Martha Pfeiffer , Dorset
