觀察細節
Very clean plumage without any tannin stain, feathering at forehead appeared more rounded than pointed, and the cheek feather line seemed more curved than angled - all commending TUSW. The eye adjoined the black of the bill but was narrowed sufficiently to suggest the typical pinched trait and not joining as widely as most TRSW would. No yellow in the lores however. Body size also seemed a bit smaller than the TRSW by comparison.
