Population justification: The global population size has not been quantified, but the species is described as rare to locally fairly common.
Trend justification: Estimated annual declines of 13% occurred in the adult population at Estação Ecológica de Águas Emendadas, Brazil between 2003 and 2007 (L. F. França and M. A. Marini in litt. 2008, França and Marini 2010). The drivers of declines are not well understood: this site is apparently well protected and has apparently suffered little anthropogenic alteration over the past 20 years since its formal protection. However, on the basis of apparent rarity in other large protected areas of cerrado, a population-wide decline approaching 30% over 11 years (three generations) is precautionarily suspected.
