Appearance:

Unmistakable. Only black and white passerine of it's size in Europe. Short rounded wings and exceptionally long tail. Wings fan-shaped and tail graded. Tail constitutes about half of the total length in adult birds. Compact body but relatively long legs. Flat crown. White wing patches/flight feathers very conspicuous in flight.

Sound:

Most notable sound a harsh, chattering "chechechecheche" used as warning call, or when mobbing predators. Rich repertoire includes soft and surprisingly varied sub-song.

Appearance:

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".
