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.

Sounds:Recorded by Edmunds Racinskis

Appearance:

Dark-bellied, long-billed shearwater with small head and elongated body. Wings long, narrow and pointed, with pale patches/bands underneath framed in dark base colour of body. Flight fast and powerful. In strong winds hand held pointing slightly backwards. The pale underwing is clearly visible in good light, but the whole bird often seems completely dark. Only shearwater in the region with completely dark underparts, except from dark individuals of the much smaller, and short-winged, Balearic Shearwater. The latter also shows deeper belly and less deep chest. At long distance, and/or bad weather, Sooty Shearwater may be confused with Arctic Skua or even young Gannets. Differs from Gannets by size, shorter neck and no white rump patch. Told from Skuas by bursting series of stiff wing-beats with alternating glides.

Sound:

Mostly heard at breeding ground. A peculiar, rhythmic, coarse moaning, with a disyllabic attack, followed by a deeper, cooing "in-breath".
