An active, unstreaked warbler with a long graduated tail that is sometimes cocked. It is yellowish below with a distinct white throat. When breeding it has a broad dark chest band (narrower in the female) that is reduced or absent in northern populations. Pairs inhabit arid savanna, shrubland, and gardens, where they glean small insects from leaves. The species’ typical song is a dry harsh “dziiip” note repeated 10-30 times in rapid succession. The similar Tawny-flanked Prinia may resemble non-breeding Black-chested Prinia, but Tawny-flanked can be identified by the rusty wings and lack of yellowish underparts.
