This is one of two common reed warblers in Taiwan. Easy to find in the weeds, especially during the period bearing the seeds. Sometimes this species perching on the wires or poles but most time stays low near the ground among the reeds. The similar species, yellow-bellied prinia had their head feathers in darker color.
