Gray's grasshopper warbler (Helopsaltes fasciolatus), also known as Gray's warbler, is a species of bird in the family Locustellidae; it was formerly included in the "Old World warbler" assemblage. The Sakhalin grasshopper warbler was formerly considered conspecific. == Distribution and habitat == This small passerine bird breeds in southern Siberia, northeastern China and Korea. It is migratory, wintering in southeast Asia. It is a species found in lowland and coastal regions, nesting in forests or thickets. == Description == The adult has an unstreaked olive-brown back, uniformly grey breast and buff underparts, with unmottled dull orange undertail coverts. The song is a short phrase, loud and distinctive; nothing like the insect-like reeling of European Locustella species, and more musical than that of Pallas's grasshopper warbler.
