Population justification: The species is described as uncommon to fairly common (Stotz et al. 1996, Remsen Jr. and Kirwan 2020). It is suspected that subspecies pabsti numbers around 15,000 mature individuals (G. A. Bencke in litt. 2021, in Silveira et al. 2023). Based on intensive field surveys, the population of subspecies espinhacensis was estimated at 880-2880 mature individuals (Freitas et al. 2019). The total population is therefore placed in the band 15,880-17,880 mature individuals.

Trend justification: Despite its tolerance of a certain level of human disturbance and habitat degradation, population declines are suspected on the basis of the large-scale conversion of grasslands to plantations (C. S. Fontana in litt. 2006, Remsen Jr. and Kirwan 2020, Silveira et al. 2023). Based on remote sensing data, it is estimated that the more numerous subspecies pabsti has lost 20% of suitable habitat to plantation between 2010 and 2020 (Silveira et al. 2023 and references therein), which equates to 22% over three generations (11.1 years). Climate change may further reduce available habitat, as campo rupestre savannas are particularly vulnerable to alterations in precipitation regimes (Freitas et al. 2019 and references therein). It is assumed that population declines are roughly equivalent to the rate of habitat loss (Silveira et al. 2023). Consequently, they are here placed in the band 20-29% over three generations and are suspected to continue into the future based on ongoing threats.
