Possible echolocation
觀察細節
Dark swiftlet with prominent white rump and pale belly identified from slow motion video. Dark throat ruling out house swift. Echolocation recording suggests more than one present but difficult to identify in the field. In this short clip see bird flying left to right passing in front of distant trees. Two video still frames of rump and belly also uploaded.
