Striated Grassbird

The striated grassbird is a large, conspicuous grassland warbler, 22–28 centimetres long, with a notably elongated tail. It has a buff-white eyebrow, olive-brown crown and hindneck marked by dark streaks, and brown-streaked upperparts. The pale buff throat and breast are also streaked, while juveniles show weaker underpart markings. Unlike many skulking grassbirds, it often sings openly from grass tops, bushes, poles or wires (Malaysia Tourism bird guide; Wikipedia).

The species is widespread across South and Southeast Asia, including Vietnam. It inhabits marshes, vegetated lake margins, wet grassland, scrub, rice fields, airfields and other open grassy places. Birds move through tall stems taking insects, larvae and other small invertebrates, then climb to exposed perches to deliver loud calls. Its combination of substantial size, heavy streaking, long tail and unusually visible singing behaviour separates it from smaller, more secretive wetland warblers (Malaysia Tourism bird guide).
