觀察細節
Minimum count by twos, based on groups flying in the same direction within a short time interval. Most of the birds I observed were juveniles. Groups of 10-20 seen in flight numerous times. At one point, I watched 2 (at least 1 of them a juvenile) trying to catch the same insect (large enough for me to see it in binoculars - a fly?) in midair; neither was successful, and then they landed within 2 m of each other in the top of a shrub.
