觀察細節

Clearly smaller and with a rounder head than nearby SNGO. Smaller bill with gray base. (Not as stubby as I'd like.) Vertical border with feathers at rear edge of bill. Had difficulty with midday glare discerning presence or absence of grin patch with binoculars Not 100% sure there's no hybridization. Will upload photos later and look forward to reviewer's opinion. (Ted K will upload better photos!)
