Distribution

The range of the White-winged Swallow is fairly broad in South America, reaching from northern Colombia, across Venezuela and continuing east to the Guianas, and  southward to Brazil, Bolivia, Paraguay, northern Argentina, eastern Ecuador, and eastern Peru. White-winged Swallows are also found in Trinidad and Tobago off the coast of Venezuela. Although often considered a resident, White-winged Swallows in the southern part of the species' range migrate. For example, in Rio Grande do Sul in southernmost Brazil, White-winged Swallows mostly are absent between mid-April and mid-September (Belton 1985). The nonbreeding distribution of these southernmost populations is not known (Turner and Rose 1989).

Endemic to South America and the southern Caribbean.

Typically White-winged Swallows are found in lowland areas along rivers, lakes or wetlands. Although they are often found around inland bodies of waters and along coastal sandy beaches, according to Turner and Rose (1989) they have also been reported in flooded llanos, dry savannas, and even into forested areas near rivers. They have been reported as occurring up to approximately 500 meters in elevation.
