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). 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 very 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 suspected to number 500,000-4,999,999 mature individuals (Partners in Flight 2019). The species is described as fairly common to common throughout its range (del Hoyo et al. 2005).
Trend justification
The population is thought to be stable (Partners in Flight 2019).
This species breeds in Mexico, although it is sometimes found in the extreme south of the U.S.A. outside the breeding season (June to August). The subspecies graysoni, which is sometimes considered a separate species, is range-restricted and found only in the north-west Mexico Pacific Slope EBA.
The species inhabits arid to semi-humid deciduous and semi-deciduous forest, thorn-forest, inland riparian woodland and edge, plantations and gardens, where it tends to forage on the ground for fruit (Collar 2005). It typically occurs from sea level to 1,500 m, although a feral population exists in Mexico City at 2,200-2,500 m.
