Justification of Red List category
This species has an extremely large range, and hence does not approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence <20,000 km2 combined with a declining or fluctuating range size, habitat extent/quality, or population size and a small number of locations or severe fragmentation). Despite the fact that the population trend appears to be decreasing, the decline is not believed to be sufficiently rapid to approach the thresholds for Vulnerable under the population trend criterion (>30% decline over ten years or three generations). The population size has not been quantified, but it is not believed to approach the thresholds for Vulnerable under the population size criterion (<10,000 mature individuals with a continuing decline estimated to be >10% in ten years or three generations, or with a specified population structure). For these reasons the species is evaluated as Least Concern.
Population justification
The global population size has not been quantified, but this species is described as 'generally common, and locally abundant; rare in some places' (Cabot et al. 2020).
Surveys within an area with high hunting pressure in Rio Grande do Sul (Brazil) estimated a density of 0.025 individuals per km2, and found that the species was absent from many survey locations (Pinheiro and Lopez 1999).
Trend justification
The species has been extirpated from some areas, such as Guaiba and Barra de Ribeiro in Rio Grande do Sul, Brazil, as a result of hunting (Pinheiro and Lopez 1999, Cabot et al. 2020). The species faces intense hunting pressure in many parts of its range, especially where it occurs in proximity to human habitation. It is thought to be declining in Brazil as a result of hunting and possibly also due to insecticide poisoning (Sick 1993, Cabot et al. 2020). It is also negatively affected by the burning of pampas grassland. It has declined in the pampas of Argentina due to hunting and agriculture (Cabot et al. 2020). However, clearing of tropical forests, and the resultant grassland habitats allow the species to move into new areas (Sick 1993).
