影音備註
Large flock creates "dirty" background on image. In the field little sound other than the birds was noticeable on this portion of the recording.
觀察細節
Very rough estimate, quite possibly low. Three separate flocks heard in trees; in each case most remained unseen. Overflight by several groups of 25-50 birds each. All birds seen clearly appeared to be RWBL, some male, some female/immature; cannot vouch that there were no other species.
