LC
Plain Chachalaca Ortalis vetula



Justification

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). The population trend appears to be stable, and hence the species does not approach the thresholds for Vulnerable under the population trend criterion (>30% decline over ten years or three generations). The population size is extremely large, and hence does not 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 is inferred to number 2,000,000 mature individuals (Partners in Flight 2019).

Trend justification
The population trend has not been quantified directly. The species seems to adapt well to habitat alterations and does not appear to be negatively affected by high hunting pressure (Peterson 2020); therefore, in the absence of evidence for any declines or substantial threats, the population is assessed as being stable.
