Population justification: The global population size has not been quantified, but the species is probably fairly common in parts of its range. The species is fairly common in Serra da Capivara National Park, Piauí (Olmos 1993), and Chapada do Araripe National Forest, Ceará, and common at Palmas de Monte Alto, Bahia (J. M. C. da Silva in litt. 1993, 1995). It was common at Coribe, Bahia, in 1987, but habitat loss probably extirpated it from this site by 1993 (da Silva and Oren 1997).
Trend justification: Despite the threats from habitat loss and degradation the overall population and distribution seem quite large and recent records have hugely extended its known range in Bahia and into Minas Gerais and Goiás (J. M. C. da Silva in litt. 1993, 1995, G. M. Kirwan in litt. 1995, J. Wall in litt. 1995, M. Marini per T. A. de Melo Júnior in litt. 1999), and the species is tentatively suspected to be stable.
