Population justification: The species is widely reported in forest across its range (WikiAves 2021; eBird 2021), but tends to avoid secondary forest (A. Lees in litt. 2021). The nominate race is fairly common in Amazônia National Park, Amazonas, and in parts of Rondônia. The race nattereri is fairly common to uncommon in north Mato Grosso and probably throughout most of its range. Surveys in the Kayapo Reserve, southeastern Amazonia recorded population densities of 2.8 individuals per km² in unhunted forest and 0.52 individuals per km² in hunted forest (Peres and Nascimento 2006). The population size is unknown.

Trend justification: Remote-sensing data on loss of tree cover with at least 50% canopy cover from the species's range indicate that approximately 17% was lost from 2000-2020 (Global Forest Watch 2021). Extrapolating over three generations (23 years), an estimated 19% was lost over the past three generations. Extrapolating forwards, it is projected that 24% of tree cover will be lost from within the species's range over the next three generations. Based on the rate of tree cover loss over 2016-2020 (Global Forest Watch 2021), it is projected that up to 30% of forest may be lost from the species's range over three generations from 2021.

This species has a high level of dependency on forest habitat, and appears to avoid areas of secondary forest (A. Lees in litt. 2021). Studies of cracids in the Pantanal have indicated that their abundances are impacted by forest fragmentation and degradation (A. P. Nunes in litt. 2021). It is considered likely that the species's population size is declining at least as fast as forest is lost. The species is also susceptible to hunting and trapping, which are likely to be causing local declines (Peres and Nascimento 2006; Peres and Palacios 2007). Assuming that the population size is proportional to the remaining area of forest, and that hunting may be causing an additional decline of up to 5% over three generations, the species's population size is suspected to have declined by 19-24% over the past three generations. It is suspected to decline by 24-35% over three generations from 2021.
