觀察細節
Refer attached photo. I had initially put this down as a little swift. However, the wing pattern seems to match closely for White-rumped needletail. The white throat expected in a Little swift also seems missing in this individual. The flight was very swift. I was photographing a group of red-rumped swallows and one individuals flight pattern seemed to be quite different from the rest and that is what drew me to this individual.
