Western Orphean Warbler (Curruca hortensis)
Kittiwake (Rissa tridactyla)
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.

CCSmall and agile gull with all black wing-tips, black legs (adults) and yellow bill. Area close to wing-tips much paler than rest of wings, and often visible at surprisingly long range (more so than the black tips). Adult winter with grey neck and black half-collar. Juveniles with black zig-zag pattern to wings, resembling pattern seen in Little Gull, Ross's Gull and Sabine's Gull. Differs from those in; no dark bar on secondaries, underparts of wing white, back grey, black on primaries reaches wing-tip. Flight action different from larger gulls; fast, stiff wing-beats and elegant maneuvering even in strong winds.
Sound:Highly vocal at breeding ground. A mewing "kitti-wake", with the pitch rising on the second drawn out syllable, and then falling. Generally silent elsewhere, except when squabbling over food.
