Barn Swallow (Hirundo rustica)
Sooty Shearwater (Ardenna grisea)
Dark blue metallic upperparts, deep red forehead and throat and light underparts. Long tail-streamers in adults and deeply forked tail. Both the metallic blue and the deep red appears black at a distance. Combination of dark throat/breast and light underparts and vent is diagnostic, and distinguishes it both from Red-rumped Swallow and the smaller martins. Juveniles are less brightly coloured with a dull red throat, and short streamers.
Sound:Characteristic calls and song. Contact call a short and sharp "weet" or "kee-weet". Song a sparkling, squeaky energetic improvisation with interspersed contact calls, often with diagnostic ending; an electric and drawn-out "su-eerrrrrrrrrrrrrrr".

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".
