Marsh Warbler (Acrocephalus palustris)
Tree Sparrow (Passer montanus)
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.

CCSounds:Recorded by Edmunds Racinskis
Differs from House Sparrow by warm brown crown, white cheeks, white (incomplete) collar and diagnostic, black cheek patch. From Spanish Sparrow by cheek patch, and lack of black breast markings. Brown and streaked rump. The black bib does not expand towards the chest. Head profile rounder and neater than House Sparrow, with slightly smaller bill. Identification by profile alone is possible with practice. Sexes and ages alike.
Sound:Distinct, high-pitched and explosive contact-call; "che-witt" typically given in flight. Second syllable rising rapidly in pitch. Most other sounds similar to House Sparrow, and may be difficult to identify. Chattering sounds are generally harder, and song slightly higher pitched than House Sparrow.
