觀察細節

Always stayed in FRGU flock. Smaller and lighter than associating FRGU. Paler, black spot behind eye. Slightly dark line through coverts, but noticeable white block along the leading edge. Would need to look into molt patterns for where this bird falls (molting into 2nd winter?). Some crappy photos and videos.
