House Martin (Delichon urbicum)
Thrush Nightingale (Luscinia luscinia)
A small, compact martin with short, forked tail and pure white rump. Underparts shiny white (including throat and vent). Upperparts dark with shiny metallic glow to head and back. Juveniles overall more dull, with white tips to tertials and dusky, brownish upperparts. Flight determined and steady. Glides more than Sand Martin, with less frequent change of direction.
Sound:Contact call a rolling "krreet". Similar to Sand Martin but noticeably dryer, more rolling and less raucous. Typically varies the pitch of the call more. Song a merry improvisation of chirping, contact call-like sounds (sometimes recalling a budgerigar). Warning call a sharp and plaintive "tsreee".

CCAnonymous, indistinct plumage and secretive behaviour makes it an easily overlooked bird (except when singing). Upperparts brown-grey, tail rufous brown. Underparts dull white. Throat with faint streaking on each side. Very similar in appearance to Nightingale, but tail is not as rufous, and contrasts more with the grayer/brownish back. Overall more drab appearance. Thrush-like behaviour despite the small size, with jumping gait, raised tail and drooping wings.
Sound:Alarm call alternates between a thin, high pitched, "piuu", and a characteristic dry, rattling, frog-like "rrrrr". Song a highly distinct mix of extremely resonant, full-bodied notes and species specific, dry, rolling, rattling sounds. Can only be confused with Nightingale, but lacks this species' interwoven series of slightly ascending, plaintive notes.
