Initially caught my attention by its longish tail with more squared tail tip compared to typical Oriental Reed Warbler (because tail feathers are broader with more rounded tip). Photos showing the wing also support Clamorous RW with P2 shorter than P5 from any angle visible. P3-4 are wingpoint with strong emargination on both feathers, and likely a slight emargination on P5 though the outer web is slightly rugged. It didn't show any strong reaction towards either song/call of Clamorous or Oriental RW though. There were also 3-4 other Oriental Reed Warblers nearby but they didn't interact with this particular bird.
