The northern populations are resident, but patagonica has been recorded on migration or in winter to northern Chile, northern Argentina, Paraguay, Bolivia, eastern Peru, Colombia, Venezuela, Trinidad, the Guianas and Panama; exceptionally, it occurs further north, with records in Nicaragua and Chiapas, Mexico. In Chile, patagonica is present all year in the north but only from late August to March in central and southern parts of the country. On migration these swallows keep to the more elevated country. They arrive in Argentina and Uruguay in August-September and leave in January-March, then north across Bolivia and Peru, Ecuador, eastern Colombia and northern Venezuela as far as Panama (Zimmer 1955). A few individuals have been recorded on the western coast, in the lowlands of the Amazon valley, and from Paraguay and western Brazil.   (Turner A, Rose C, 1989)
