Marsh Warbler Bird is very like the Reed Warbler, often identified by habitat and voice alone. It has a slightly shorter bill, a more rounded head shape, a bolder, pale supercilium in front of the eye and a bolder eyering, giving the face a gentler expression. The overall colouration of the upperparts is a warm grey-brown with an olive tinge, and the underparts are less buffy, more off-white with a yellowish-buff tinge. In fresh plumage it shows pale crescents on the tips of the primaries, and the legs are yellowish-pink.
Marsh Warbler Bird is a rare summer visitor to Britain. Occasional songsters appear in the south and east, but former breeding sites have been largely abandoned. It occurs widely across continental Europe and southern Scandinavia, right up to the Channel coast. It avoids the wetter habitat choices of some of its relatives, favouring rank growth of tall herbage, young trees, scrub and bushes, often in the zone between woodland edge and growths of reeds, or between swamp and drier vegetation.
The calls of Marsh Warbler Bird are similar to those of the Reed Warbler, such as a "dchrrr" given in alarm, a sharp loud "tchak", some quiet "tuc" notes and also a "wheet-wheet-wheet". It is a remarkable songster, giving a sweet fluid warbling chatter at a fairly fast but measured tempo with pauses in between, much of which is made up of expert mimicry, which is blended into the nasal babbling, trilling and churring, often giving characteristic harsh "zi-chay" notes and high liquid trills and tremolos, too complex and varied to attempt to transcribe here meaningfully! It often sings from a semi-exposed perch in a bush or similar, and frequently includes mimicry of Common Tern, Barn Swallow, House Martin, Blue Tit, House Sparrow and Chaffinch. It has been recorded as mimicking at least 99 European and 113 African species!
