Barn Swallow (Hirundo rustica)
Savi's Warbler (Locustella luscinioides)
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".

CCReedbed-living, dull coloured warbler with fan-shaped tail. Under tail coverts lacking pale fringes or markings. Vague and short supercilium. Differs from other locustella by unstreaked chest, back and under tail coverts. From Reed Warbler and Marsh Warbler by very long and buff under tail coverts, smaller head and pinkish legs.
Sound:Song insect-like and high-pitched. A monotonous stream of even clicks similar to the whirring of a sewing machine. Song most similar to Grasshopper Warbler but faster (each click hard to distinguish), and lower pitched with less, ringing quality, due to less prominent high frequencies. At closer range a Robin-like, accelerating ticking is heard, introducing the actual song.
