Redwing (Turdus iliacus)
House Martin (Delichon urbicum)
Small thrush with rufous flanks, strong white supercilium and whitish moustache stripe. Upperparts evenly brown, underparts white with dark spots on chest and sides. Underwing coverts rufous. Fairly compact build, with slightly more pointed wings and shorter tail than Song Thrush. Juveniles less brightly coloured, with buff spots on upperparts. Behaviour less secretive than Song Thrush.
Sound:Song delivered in two parts. First a simple, melodic phrase of 3 - 6 notes, usually followed by a more silent, indistinct, fast and less melodic, chattering sequence. First part highly variable from place to place, but constant in individuals. Often causes confusion when a new dialect is heard at a distance, since only the first part is far-reaching, and the diagnostic two-part structure gets lost. Contact call a thin, drawn and sharp "sreee". Often heard at night during migration. Alarm call harder, dryer and more raucous than other thrushes.

CCA 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".
