Northern-Rough-winged Swallow Wing Structure

Copyright © Lewis Scharpf

Stelgidopteryx serripennis
Probably a male as the leading edge wing hooks are distinct and at an angle.
Wing Structure
Note the outher wing feathers which have small hooks or points
on their leading edges.
The function of these hooks is unknown.
