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:

Largely unmistakable, even at a distance when bald head is not apparent. Note short legs and short, thick neck without bulbous head. In flight note that the legs are not protruding behind tail, and that the wings usually show 3-4 "fingers". Frequent soaring flight, as opposed to Glossy Ibis.

Sound:

Mostly silent. Vocal at breeding ground, where a range of guttural calls can be heard, "yarrp, yarrp" etc.
