Purple martins migrate seasonally between North America and South America. In summer months, they can be found in the United States, Canada, Mexico and Central America. In winter, they frequent Brazil, Colombia, Venezuela, Guyana, Suriname, Peru, Bolivia, Paraguay and Argentina.
Purple martins are large swallows, and like their cousins the American Cliff Swallows, they migrate extensively between North and South America. Purple martins generally spend their springs in North America. Most of their North American range is east of the Rocky Mountains, although there is also a small piece of their breeding range that hugs the Pacific coast from Baja California to Oregon. When migrating down to South America, they prefer to fly overland. They migrate over Central America and Mexico, though some do stay in Mexico to breed.
