Species of bird

The northern rough winged swallow (Stelgidopteryx serripennis) is a small, migratory swallow. It is very similar to the southern rough winged swallow, Stelgidopteryx ruficollis.

The genus name, Stelgidopteryx, is from Ancient Greek and means "scraper wing" and the species name, serripennis, is derived from Latin and means "saw feather".

Six subspecies of the northern rough winged swallow are currently recognized. S. s. serripennis is the nominate subspecies and can be found to occur in southern Alaska and Canada to the southern United States. They are found to usually winter in southern Florida and from southwestern Mexico to Panama. It was described by Audubon in 1838. The males' undertail coverts are longer and broader than those of the females. 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 those of the males. Juveniles can be distinguished from adults by their reddish brown wing bars. 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.

The call of this swallow is described as a short, harsh zeep. This call is similar to the call of the bank swallow.

The northern rough winged swallow is native to Bahamas, Belize, Canada, Cayman Islands, Costa Rica, Cuba, El Salvador, Guatemala, Haiti, Honduras, Jamaica, Mexico, Nicaragua, Panama, Puerto Rico, Saint Pierre and Miquelon, Turks and Caicos Islands, and the United States. They are vagrant to Aruba, Barbados, Bonaire, Sint Eustatius and Saba, Curaçao, Dominican Republic, Guadeloupe, and Sint Maarten. It has been observed that the clutch size decreases with decreasing latitude. They have also been recorded to winter in the Caribbean. Although this is true, there is a report of some feeding on cracked corn. To drink, they skim the surface of the water with their wing and then drink on their wing.

The northern rough winged swallow is classified as least concern by the IUCN. Although its population is declining, it is not declining fast enough nor is its range small enough to justify a classification of vulnerable. In addition, this species is estimated to be composed of about 15 million individual birds, so it is not vulnerable under the population size criterion. This swallow has been found to adapt well to humans and sometimes nests in artificial cavities created by them.
