觀察細節
It appeared very large and had an incredibly slow languid flight. Its extensive white rump and overall size would favour Pacific Swift over Blyth's Swift comparing it against criteria detailed in Leader, P. J., 2011. Taxonomy of the Pacific Swift Apus pacificus Latham, 1802, complex. Bulletin of the British Ornithologists’ Club 131 (2): 81–93. However, Pacific Swift is only known from five old specimens in India per Leader, P. J., Zyskowski, K., Bird, B., Khot, R., van Grouw, H., & Praveen J., 2020. Status of ‘Fork-tailed Swift’ Apus pacificus complex in India. Indian BIRDS 16 (5): 135–139.
