This swiftlet was found in Nan'au, Yilan, Taiwan on 2018/11/03.
Though I considered it as a medium to large size swiftlet in slim shape in the field (I had only little experience in swiftlets due to their rarity in Taiwan), obvious white lower belly were shown on the pictures I took.
I'm wondering about it as Aerodramus sp. or Collocalia sp.?
If it was Collocalia sp., could I ID it as Grey-rumped Swiftlet (Collocalia marginata) due to the paler rump and its closer distribution (Luzon) to Taiwan?
Part 1 (total 35 pics, all pics indicate the same individual)
