Fairly common to common summer migrant from winter grounds in Africa. Favors marshy and scrubby habitats with reeds, brambles, and bushes, usually not in extensive pure reed beds. Often heard but can be hard to see: prolonged song much like a reed warbler but slightly faster-paced, jerkier, and overall rougher-toned. Most striking plumage feature is broad, pale buffy eyebrow; otherwise, upperparts rich dark brownish overall (with indistinct streaking), underparts buffy. Juvenile (in summer–autumn) has fine dusky streaks on breast.
