The southern rough-winged swallow (Stelgidopteryx ruficollis) is a small swallow. It is found in Central and South America and Trinidad.
The adult is brown above, with blackish wings and tail and a pale grey rump. The throat and upper breast are rufous with the lower underparts yellowish-white. The tail is slightly forked.
Southern rough-winged swallows forage for insects in flight, usually flying low with a slow deliberate flight.
