觀察細節
Extremely high flying apparent swift. Not visible to naked eye, only saw by chance as I observed flyover BTPIs through binoculars. It was near 5-6 other very high flyers that I think were maybe swifts or Purple Martins, but not sure. Lots of gliding and slower wingbeats than VASW. Hard to say for sure it wasn't another martin/swallow.
