Justification of Red List category
Although this species may have a restricted range, it is not believed to 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). The species is described as 'common' (Stotz et al. 1996).
Trend justification
The population has reportedly declined; the main drivers of the decline are trapping for the cagebird trade as well as habitat loss (Simpson 2020).
Tree cover loss within the range is very low (1% over ten years; Global Forest Watch 2021, using Hansen et al. [2013] data and methods disclosed therein), but the impact of trapping on the population size has not been quantified. Tentatively, it is suspected that the population is declining at a rate of 1-19% over ten years.
The main threats to this species are trapping for the cagebird trade and habitat loss through logging of forests for agricultural purposes (Simpson 2020).
