Genus Stelgidopteryx

Southern Rough-winged Swallow - It occurs in Central and South America from Honduras south to northern Argentina and Uruguay. It also occurs on Trinidad. Southern birds of the nominate race S. r. ruficollis, are migratory, moving north in winter, but the northern S. r. aequalis is sedentary.

Northern Rough-winged Swallow - Adults are 13–15 cm in length, brown on top with light underparts and a forked tail. They are similar in appearance to the Bank Swallow but have a dusky throat and breast. They are closely related and very similar to the Southern Rough-winged Swallow, Stelgidopteryx ruficollis, but that species has a more contrasting rump, and the ranges do not quite overlap.
