Cotopaxi, Ecuador, September 2010
USA and Canada: Main breeding range in the U.S. from North Dakota and southern Manitoba east to southwestern Ontario and Michigan south to eastern Nebraska east to Indiana. Localized in Ohio, New York, Vermont and New Jersey. Winters in eastern Texas, Arkansas, Louisiana, and Florida.
Central America: from Mexico to western Panama.
South America: In the north limited to mountain ranges, but in the southern cone more widespread; also found in the Falkland Islands.
Taxonomy
There are numerous subspecies. These can be devided into two main groups which sometimes are considered as separate species: The Sedge Wren (Cistothorus stellaris) from North America and the Grass Wren (Cistothorus platensis) from South America.
Subspecies
Alternatively[1], the species can be divided into several subgroups which require additional research: stellaris from USA and Canada, the Middle America group from Mexico to western Panama, the polyglottus group from the Andes and other mountains in northern South America, the platensis group of Argentina and Chile, and the falklandicus group from the Falkland Islands.
