Western Orphean Warbler (Curruca hortensis)
Shag (Gulosus aristotelis)
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.

CCEasily distinguished from Cormorant in breeding plumage, but at other times easily confused with congeners. Smaller than Cormorant, with a more slender neck and rounded head. Bill slender and straight. Steep forehead with peaked front crown, differs from the wedge shaped head of Cormorant. Bill often with yellow tinge (never in Cormorant). Flies with quicker wing-beats and straight neck (Cormorant with bulge). Often dives with a high jump. Juveniles with darker underparts than Cormorant, and often an obvious brownish tinge. Rare in brackish water.
Sound:Very deep and harsh voice heard at breeding ground. Deep grunts alternated, or ended with clicking sounds.
