Appearance:

Plain and characterless plumage, but conspicuous song. Larger than Sedge Warbler, with larger wings, broader tail and tail-base. Very similar to Reed Warbler, and very hard to distinguish by plumage alone. Rump of Marsh warbler shows less contrast to back, and flanks have a yellowish tinge. Bill slightly shorter and less pointed. Differs from Blyth's Reed Warbler by longer primary projection, yellowish lower mandible and paler legs. Juveniles especially hard to identify because of even fainter plumage field marks. Less common in reed beds than Reed Warblers, and more attached to bushes with lush undergrowth.

Sound:

Song extremely varied and full of mimicry of both European and African species. Up to 75 species imitated by the same bird. Phrases often repeated 2-4 times, and different phrases may overlap. Nevertheless, clearly defined phrases with marked pauses. Sometimes more flowing streams of notes, but less so than Icterine Warbler. Most similar to Icterine and Blyth's Reed Warbler. Softer timbre than Icterine, and not so loud. More defined pauses and staccato tempo, and lacks Icterine Warbler's nasal high-pitched calls. Differs from Blyth's Reed Warbler in fewer repetitions of each phrase, and lack of said species' whistling, arpeggio-like calls. Typical sequence is a hoarse, drawn "ti-chaaa". Alarm call a short "chepp" with clipped ending.

Appearance:

At a distance quite similar to Guillemot. Bill deep, rectangular and with white markings. Flanks unstreaked and armpits white. Tail longer than in Guillemot, with legs not protruding behind tail in flight. Tail often held clear of the surface when swimming. Cheeks white in winter, with broad, short and black eye stripe. Neck collar short and wide. Upperparts blacker, and underparts whiter than Guillemot. Heavy neck, head and bill, in combination with the long tail, gives it a front heavy, and different profile from Guillemot, whether perched, swimming or flying. Top of head in line with tip of uptilted bill when swimming.

Sound:

Very coarse and deep voice. Grunting or snore-like, with little phrasing. Mostly heard at breeding ground, but also sometimes at sea.
