Range DescriptionThis species is currently restricted to the cerrado (tropical savanna) of central and south-east Brazil in Distrito Federal, GoiÃ¡s, Minas Gerais, Mato Grosso do Sul, Tocantins, SÃ£o Paulo and formerly ParanÃ¡ (L. F. Silveira in litt. 2012). In 2008, it was found in relatively degraded but extensive cerrado south of Araguainha, Mato Grosso (Kirwan 2009). A specimen is known from Misiones, Paraguay, and two were taken in Argentina in the early 1900s (M. Pearman in litt. 1999), from near the rÃo Bermejo in either Chaco or Formosa, but there have been no further records from the country. Recent records are few and scattered, but up to four calling birds have been found in c.2 ha (Silveira and Silveira 1998) and, with knowledge of its voice, it may prove to be more widespread; however, it is now probably largely restricted to a few widely-spaced protected areas (L. F. Silveira in litt. 2012, A. Lees in litt. 2013), and isolated populations may now be vulnerable to local extinction â in SÃ£o Paulo state the species may have been lost from Itapetininga (F. Olmos in litt. 2013).
