Stelgidopteryx is a small genus of swallows.
It contains the Northern Rough-winged Swallow, Stelgidopteryx serripennis.
Adults are brown on top with lighter underparts and a slightly forked tail. They nest in cavities but do not excavate their holes or form colonies.
"Rough-winged" refers to the serrated edge feathers on the wing of this genus; this feature would only be apparent in the hand.
