Large, two-toned warbler, warm brown above with a pale, unstreaked breast. May recall Eurasian Reed-Warbler but note long undertail coverts with indistinct pale tips. Not typically easy to see, but singing birds are usually partially exposed. Breeds in extensive reed beds and winters in various habitats with tangled, rank vegetation. The song is a metallic, continuous, low-pitched, and insectlike series like Common Grasshopper-Warbler but lower pitched. Calls include a low “tik tik tik”, as well as a higher-pitched “tsip.”
