Breeds in Siberia, parts of Central Asia, Mongolia and farther eastwards, in soggy grassland with dense shrubbery or in thick riverside vegetation (reeds, rushes, willows), in damp forest clearings or bog margins etc. Very rare autumn vagrant in Europe. Mostly remains concealed low down in vegetation, difficult to see.

Identification: Can be described as something between Grasshopper Warbler and Sedge Warbler. Has pale super-cilium which is a touch more prominent than Grasshopper’s, but nothing like Sedge’s long and well-marked one. Ground color of upperparts usually a shade more reddish-brown, not so olive-grey as Grasshopper’s, and dark spotting on crown, back and uppertail-coverts averages heavier (though some similar), while rump is often contrastingly reddish-brown and unstreaked (quite like Sedge Warbler). Most important features: tail-feathers have white tips can be worn off, or be slightly more diffuse on some juveniles) with dark subterminal marks; tertials dark brown with sharply defined light brown edge to outer web and (almost without exception) a white spot near tip of inner web; undertail-coverts entirely (or almost so) unstreaked, rusty-buff(with whiter tips). Underparts plain off-white with only faint yellow-buff wash to breast and flanks (adult), or distinctly yellow-buff with warmer tone to throat, breast and flanks and with breast spotted (mainly, but not exclusively, immatures).
