Progne subis, commonly known as purple martins, inhabit the Nearctic region and can be found across North and South America. Progne subis is a migratory species that breeds in North and Central America and overwinters in South America. The northern extent of the breeding range includes the Canadian Territories of Alberta, Saskatchewan, and southern Manitoba. Purple martins breed across the eastern half of the United States, and also may be found along the Pacific coastline including the entire Baja Peninsula.

Purple martins overwinter across most of South America including the countries of Colombia, Venezuela, Guyana, Suriname, Ecuador, Peru, Brazil, Bolivia, Paraguay and Argentina. Their winter range has been recorded to be South American lowlands anywhere east of the Andes Mountains. Concentrated populations have been found to winter in Bolivia and some provinces of Brazil. There have been some records of purple martin populations found in the British Isles, but these birds rarely migrate outside of the Americas.
