Population justification: The global population size has not been quantified, but this species is described as 'uncommon' (Stotz et al. 1996).
Trend justification: The population is suspected to be in slow to moderate decline owing to on-going habitat destruction. Despite the extensive destruction of dry forest since the early 1960s, populations associated with limestone outcrops in Goiás and Tocantins appear to be stable at present (T. Dornas in litt. 2013). There are, however, intentions by mining companies to explore the potential extraction of agricultural products from these limestone outcrops in the future.
