LC
Montezuma Quail Cyrtonyx montezumae



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). 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 has not been quantified given recent taxonomic splits, but it is thought to be very large.

Trend justification
The species is undergoing a moderate decline (Partners in Flight 2019). This decline is thought to be caused by ongoing threats such as deforestation, overgrazing and hunting in large parts of its range (del Hoyo et al. 1994).
