Appearance:

Anonymously brown and dark brown warbler. Slender bill, short rounded wings and broad waist and tail. Base colour varies from olive-brown to yellowish buff. Streaking also varies from diffuse to marked, and is most prominent on sides of throat and upper chest. juveniles are more streaked than adults. Rufous/olive fringes to tertials are broader on outer side (as opposed to Pallas' Grasshopper Warbler). Secretive bird. Generally discovered by song.

Sound:

Song insect-like and high-pitched. A monotonous stream of even clicks similar to a running fishing line. Maintained for seemingly endless periods, and often hard to locate. Song most similar to Savi's Warbler but is slower (each click more separated), and higher pitched with a metallic, ringing quality. Short sequences of song also functions as contact call. Also a Robin-like "tick".
