觀察細節
Singing occasionally in tall pines surrounding water trough. Clean white underneath including undertail with small area of yellowish wash at vent and flanks. Very clean uniform grey uppers, back and head, highly contrasting white spectacles. Song slightly slower, lower pitched than Cassin’s to my ear. Smart phone recording available. Few photos. After several minutes of singing in area, bird flew roughly 100m+ away and sang. Did not respond to Cassin’s song recording from Sibley app, but immediately responded to Plumbeous recording from Sibley and returned to pine directly above me and sang. (Recordings played back just once for each species).
