Great Reed Warbler

The great reed warbler is a thrush-sized warbler and the largest of its family, 16–21 centimetres long with a wingspan of 25–30 centimetres, weighing 22–38 grams. The adult has unstreaked brown upperparts and dull buffish-white chin and underparts, a flattened forehead and a strong, pointed bill. It looks very much like a giant common reed warbler but with a stronger supercilium. The sexes are identical, as in most Old World warblers, though young birds are richer buff below.

An insect-eating warbler, it breeds throughout mainland Europe and the western Palearctic and migrates to sub-Saharan Africa in winter. It favours reed beds in the breeding season, and lives in reed beds, bush thickets, rice fields and forest clearings in winter. Sexual dimorphism is relatively low, and the species mates both polygynously and monogamously. (Wikipedia, general species account)
