Population justification: The global population size has not been quantified but is believed to be large given the range and frequency of records in suitable habitat. Although it is considered scarce in most part of its range (Wells 1999, Eaton et al. 2016), it is not considered likely to meet or approach the threshold for listing as Threatened (<10,000 mature individuals).
Trend justification: Suspected to be declining because of forest loss throughout its range. Over the past three generations (14.1 years; Bird et al. 2020), forest loss in this species' range has been equivalent to 27-28% (Global Forest Watch 2022, using data from Hansen et al. [2013] and methods disclosed therein). Because this rate was similar between 2016 and 2020, with little indication this will slow in the future, the same rate is projected over the next three generations. As a forest-dependent species, the population is suspected to be declining at a rate broadly similar to that of forest loss although its utilising of degraded habitats (in, e.g., Singapore) suggests the rate of decline may be slightly less.
