Population justification: The population size is suspected to fall in the range 500,000-5,000,000 mature individuals (Partners in Flight 2019, see also Panjabi et al. 2019).

Trend justification: The species has undergone a small or non-significant decline between 1970 and 2017 (Partners in Flight 2019). A remote sensing study found that forest within the range has been lost at a rate of 5% over three generations (Tracewski et al. 2016). Assuming that population declines are proportional to forest loss, the species may be declining at <10% over three generations.
