Data Zone
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 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 50,000-499,999 mature individuals (Partners in Flight 2022).
Trend justification
The species has become locally extinct in parts of its range, likely as a consequence of extensive deforestation (Collar et al. 2020). It is moreover captured for trade, albeit in very low numbers (Collar et al. 2020).
Tree cover within the range is lost at a rate of 16% over three generations (Global Forest Watch 2022, using Hansen et al. [2013] data and methods disclosed therein). Apart from forests, the species also occurs in plantations, woodland, savanna, agricultural areas and open habitat (Collar et al. 2020); consequently, population declines may be slower than the rate of tree cover loss suggests. The impact of trapping on the population size has not been quantified, but it assumed to be low. Tentatively, population declines are here placed in the band 1-19% over three generations.
