House Martin (Delichon urbicum)
White-backed Woodpecker (Dendrocopos leucotos)
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".

CCUpper back strongly barred, lower back all white (barred in south-east Europe subspecies). Underparts streaked. Whole crown red in male. Vent pinkish red, not deep red as in Great Spotted, and less marked. Most likely to be confused with Middle Spotted Woodpecker, but is clearly bigger, has longer bill and black moustache stripe connects to base of bill. Easily recognized in flight due to strong wing-bars and white lower back.
Sound:Drumming noticeably longer and more powerful than Great Spotted, with accelerated ending (similar to Three-toed Woodpecker but faster). Contact call similar to Great Spotted, but slightly deeper and softer; "kjuk".
