River Prinia Prinia fluviatilis

An active, slender, unstreaked warbler with a long graduated tail that is sometimes cocked. Gray-brown above and pale below, with a distinctive pale eyebrow. Found near water, but in arid areas, in tall grass, reeds, and bushes. Similar in appearance to Tawny-flanked Prinia, but slimmer and paler below, and also usually distinguished by habitat and song. The song is a quick series of high-pitched “seep” notes, similar to Tawny-flanked Prinia’s but higher-pitched, purer, and less scratchy.
