Breeding range restricted to southern South America, from Atacama, Chile in the west to Rio Negro, Argentina in the east (possibly even further north than this). The southern limit extends to the tip of South America, in Tierra del Fuego.
Individuals residing in the northern part of this range are year-round residents, but birds in the southern part of this range migrate north in winter. The nonbreeding distribution is poorly known, but extends to northern Argentina, extreme southern Brazil, and Uruguay. It is at least a vagrant to Bolivia, and perhaps is a regular migrant there (Turner and Rose 1989).
