Appearance:

Small and restless species easily confused with Sedge Warbler, Acrocephalus schoenobaenus, but showing both plumage and structural differences. Plumage differs from A. schoenobaenus in; broad, white supercilium ending without narrowing, dark crown (usually appears black), pure white throat, grey ear-coverts, dark legs and warm-rufous flanks, rump and neck. Facial markings recalling firecrest. Very short primary projection and longer, more evenly rounded tail recalling Wren when raised. Bill thinner than A. schoenobaenus. Skulky behaviour, forages low in vegetation, on ground or near water surface. Some variation in both size and plumage between western and eastern subspecies.

Sound:

Contact call a dry "trrrt", similar to corresponding call of Sedge Warbler. Song most resembling that of Reed Warbler (A, scirpaceus), but often includes diagnostic (unique among congeners), pure-sounding note sequence resembling crescendo of Common Nightingale (L. megarhynchos), before launching into typical Acrocephalus sounding song. This latter type can be sustained for some time without the diagnostic sequence and is more difficult to distinguish from A. scirpaceus. Note faster tempo and more variation.

Appearance:

A featureless, bulky bunting. Larger than Yellowhammer, but with a shorter tail. Combination of size, build, flight-pattern and sound important for identification. Recalls the bigger larks in build. Takes off with a loose and surging flight, often with legs dangling underneath. Undulations particularly strong just before landing. Wings dark, and tail without white feathers or markings. "Tooth" in upper mandible visible at close range when singing. Bill and legs yellowish pink. Often shows an indistinct, dark breast patch.

Sound:

Song diagnostic. A brittle, jingling and accelerating phrase of about 2 seconds duration. Repeated in a monotonous manner, to form a typical soundscape of fields where it is numerous. Often compared to the sound of a chain of small keys. The phrase starts with a few staccato, ticking sounds that progress into a dry trill, followed by a short ritardando. Calls with a dry "chep" or a brittle "vitt".
