Marmora's Warbler (Curruca sarda)
Sooty Shearwater (Ardenna grisea)
Very similar to Balearic Warbler but breeding range does not overlap. Also easily confused with sympatric Dartford Warbler due to similar build with long tail, high crown, short wings and spiky bill. Told from latter by all over lead-grey plumage, lacking vinous underparts. Female similar to male but lacks dark lore and throat is paler . Immature birds are very similar to immature Dartford Warbler and are best identified by call, but have less brown back, paler throat and dirtier and greyer underparts.
Sound:Song hurried and similar to both Sardinian, Dartford and Spectacled Warbler, but is softer with more tinny timbre. Interwoven soft rolling "trrrrtrrr" usually become more prominent towards the end of each phrase which often is concluded by 3-4 clear whistling "wit". Alarm call a short, Stonechat-like and grating "treck", very different from both Balearic and Dartford Warbler.

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".
