Western Orphean Warbler (Curruca hortensis)
Sooty Shearwater (Ardenna grisea)
Large Sylvia with dark hood and pale iris (adult birds). Lacks red orbital ring of Sardinian Warbler. Tertials and coverts without pale fringes. Very similar to Eastern Orphean Warbler (S. crassirostris), but generally the distribution of the two do not overlap. Typical birds also show some differences in plumage like; no dark centres to under tail coverts and warm buff underparts, flanks and vent (variable). The border between the dark hood and grey neck is more diffuse, the back is browner and the bill slightly shorter. Young vagrants with poorly developed characters may be inseparable from S. crassirostris by appearance. Both species differ from Lesser Whitethroat by; stronger bill, no white crescents around eye and darker upper tail. Movements less agile than smaller congeners.
Sound:Alarm call a short and sharp "tek" recalling Blackcap, often given in series. Also a dry, rasping "turrrr". Both calls are more or less identical to S. crassirostris. Song much more different from latter, but timbre of fluting sounds is similar, recalling that of Blue Rock Thrush. Overall the song is simpler than S. crassirostris, with shorter phrases, longer pauses and a more restricted register. Motifs consists largely of pleasant fluting, often dominated by alternation between two notes, and are often repeated with small variations.

CCDark-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".
