LC
East Brazilian Chachalaca Ortalis araucuan



Justification

Justification of Red List Category
This species has a very 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 population size has not been quantified, but the species has been described as 'fairly common in many parts of range' (del Hoyo et al. 1994).

Trend justification
The species is generally common, even in densely populated areas. Although the species is thought to tolerate secondary habitats and human activity reasonably well, local declines are reported owing to habitat destruction and hunting (del Hoyo et al. 1994).
