Northern Rough-winged Swallow
Stelgidopteryx serripennis
Summary 4
The northern rough-winged swallow (Stelgidopteryx serripennis) is a small, migratory swallow. It is very similar to the southern rough-winged swallow, Stelgidopteryx ruficollis. Adults are 5.1-5.9 inches in length, brown above with white underparts, a small bill, and a forked tail. Their throat is a white with a brownish-grey wash, and below the throat are its white underparts. The males' under tail coverts are longer and broader than that of the females.[7] The males also have hooked barbs on the outer web of their outer primary wings. The barbs on the females are shorter and straighter than that of the males. Juveniles can be distinguished from adults by their reddish-brown wing-bars. The COSA lies in the breeding range of this species, and it has only been recorded in the COSA in June.
