Appearance:

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".

Appearance:

Small size diagnostic. Small head in relation to body size, and distinct short white supercilia. Slightly protruding bill. Rather dark face, with only fine white markings and stern look. Juvenile lacks finely spotted crown. Bounding, woodpecker-like flight.

Sound:

Calls in a clear voice, like a straight note blown on a recorder. Each note often followed by a rhythmic, trisyllabic accent a whole tone deeper than the first note.
