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:

Like a pale, giant Tawny Owl. Yellow bill, long, evenly barred, tail. Eyes dark. Facial disks pale, unmarked and almost fused, lacking the dividing wedge of Tawny Owl. In flight, note lack of pale base of primaries and much slower wing-beats than Tawny. Mild facial expression, but very aggressive at breeding ground.

Sound:

Song: 6 -10 evenly spaced "ho"'s, starting silently and gradually rising in volume and pitch. Also an accented "ho-ho, ho-ho-it, ho-ho", three middle notes ascending and the two notes before and after descending. A variety of barking social sounds.
