Justification of Red List category
This species's population size is suspected to be declining rapidly as a result of ongoing deforestation across its range, as well as subsistence hunting. For this reason, it is listed as Vulnerable.

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.

This taxon occurs as two subspecies: the nominate race in north-central Brazil, south of the Rio Amazon from the lower Rio Madeira to north Pará; and the race nattereri in south and west Amazonia (Rondônia east to south Pará, south to west W Goiás and Mato Grosso do Sul), and south into Bolivia.

The species inhabits river-edge and lowland evergreen forest, including Terra firme and seasonally flooded forest, but tends to avoid secondary forest (A. Lees in litt. 2021). Flocks of up to 30 have been recorded.

The species is threatened by hunting for food, and habitat loss. Deforestation has impacted severely on the habitat of this species in Mato Grosso, Rondônia and Pará (Global Forest Watch 2021), principally due to road building, ranching, agriculture, mining, hydroelectric development and urban growth (Cleary 1991, del Hoyo et al. 1994, Strahl et al. 1994, Stotz et al. 1996). Fires have also caused significant habitat destruction in recent years, particularly in the Pantanal (A. P. Nunes in litt. 2021, Garcia et al. 2021, B. Phalan in litt. 2021). The severe fires were linked to drought conditions and land use changes, and are expected to increase in frequency as these factors continue (Garcia et al. 2021). Forest degradation through selective logging also impacts on the species (Menton 2003). The species is hunted for food, particularly in the north of its range (A. Lees in litt. 2021), and sometimes at unsustainable levels (Peres and Nascimento 2006); studies have shown its abundance to be significantly affected (Peres and Palacios 2007).

Conservation Actions Underway
It occurs in a number of protected areas. It is listed as nationally Near Threatened in Brazil (MMA 2014). A captive population is maintained (del Hoyo and Sargatal 1994).

Conservation Actions Proposed
Carry out surveys across its range to gain an estimate of the population size. Monitor population trends. Study the impact of hunting on the species's population trends. Monitor hunting levels. Continue to monitor rates of deforestation across the species's range.
Expand the protected area network to effectively protect IBAs. Effectively resource and manage existing and new protected areas. Enforce legislation prohibiting hunting and forest clearance across its range.
