Northern Rough-winged Swallow

I assume this swallow is a Northern Rough-winged, since Southern Rough-winged Swallows have tawny throats. We found it near the Ensenada Lodge in lowland Costa Rica on 8 July 2017. Both species are found in Costa Rica. Ensenada seems a bit low for breeding Northern Rough-wings, which are found at all elevations when they are joined by northern migrants.
