Pallas's Grasshopper Warbler

Furtive streaky brown warbler; typically buries itself deep in tangled vegetation and is very difficult to see. If seen well, note well-streaked upperparts, long wedge-shaped tail, and rufous rump. Only other well-streaked Locustella warbler in range is the smaller Lanceolated, which has a shorter tail and more extensive streaking on the underparts. Favors wet habitats; breeds in boggy taiga and vegetated riverbanks, winters in reedbeds and marshy fields. Clattering song reminiscent of reed warblers. Call a sharp “tik”; also gives a rapid-fire dry rattle.

The Pallas's grasshopper warbler (Locustella certhiola) is a rare migrant to Sri Lanka. Its natural habitat is in tall grasslands with denser vegetation, often near water sources like bogs or wet meadows.

The Pallas's grasshopper warbler's diet consists of insects and occasionally vegetable material.
