觀察細節
Cheeks are pale compared to Cliff's chestnut cheeks. Buffy nape, rump, flanks, and undertail coverts. The bird flew differently than Cliff and wasn't associated with them. It hung out with a pair of Barn Swallows at lower altitudes. I followed this bird for a long time to get pictures and study field marks. Very difficult to photograph.
