Appearance:

A long-tailed and relatively long-winged Locustella, with olive-brown plumage and pale belly. Conspicuously broad, rounded tail, and substantial vent. Under tail coverts brown with with prominent pale fringes, and almost reaches tail tip. Faintly streaked throat and breast. Rump and tail warmer brown than back. Faint and short supercilium and pale eye-ring. First long primary with pale outer web, and a slight curve. Song-posts often more exposed than Grasshopper Warbler.

Sound:

Song an insectlike, buzzing like Grasshopper and Savi's Warbler, but easily distinguished from those by it's distinct steam locomotive-like rhythm. About 8 accents per second. Perhaps easier to confuse with certain species of ground crickets or cicadas than it's congeners. Contact call a sharp "tsikk-tsikk", similar to Savi's Warbler.

Appearance:

Like a large Willow Warbler, with distinct dark eye-stripe. Supercilium marked, but narrow. Starts at base of bill, continuing far behind eye. Wing-bar distinct on greater coverts, and sometimes on median coverts too. Primary projection long. Bill long and relatively heavy with orange base. Flanks often slightly grey, and throat sometimes with faint streaking. Appearance robust, but elegant. Moves faster and with more confidence than congeners.

Sound:

Call and song diagnostic. Song a rattling series of 20-30 single syllables. Repeated as a monotonous phrase in stable pitch, lasting 2-4 seconds. Starts more softly with volume rising throughout each phrase. Contact call equally unique. A hard and short "tsrrt", recalling contact call of Dipper. Often given as introductory part of song.
