觀察細節
First heard at 0550. "Occupied behavior" observed with sub-canopy flight and circling over the stand by two birds flying side by side. A much shorter period of detections this morning along with many few detections, both auditory and visuals. Last visual of 2 silent birds leaving the stand at 0625. The sound file is of a single bird circling overhead that was joined by a second silent bird shortly after the second "keer" call was given.
