Taxonomic note
Previously listed as Trichixos pyrropygus (del Hoyo and Collar 2016) but moved to Copsychus on the basis of unpublished genetic data (Per Alström, in litt. via WGAC) that support a broad Copsychus. Genus name is masculine, species name is adjective, so, despite original spelling, species name must be corrected to masculine form. Monotypic.

Population justification: The population size of this species has not been quantified. However, it is typically described as scarce to uncommon (Wells 2007, Mann 2008, Eaton et al. 2016) and in Sarawak, Borneo, a density of 10 birds/km2 was recorded (Fogden 1976). Consequently, although the population size has not been estimated, it is not considered likely to meet or approach the threshold for assessment as Threatened (<10,000 mature individuals).
Trend justification: Suspected to be declining because of forest loss throughout its range. Over the past 10 years, forest loss in this species' range has been equivalent to 18–20% (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 the that of forest loss, although it can tolerate some degradation. In addition, this species is prized for the bird trade. Symes et al. (2018) assigned probability curves according to expert opinion on trade desirability in conjunction with accessibility (based on a distance to forest edge from remote sensed forest data) to determine likely rates of population loss over the next three generation or ten-year period: across the species' range, the estimated loss was 27% because of hunting alone, although this analysis had no term to account for reproduction, used a slightly longer three-generation time period (11.4 years) than that used here, and analysed only Indonesia where trapping pressure is at its highest; consequently, this figure may be overly pessimistic. Combining these data, the species is suspected of declining at an ongoing rate of 20-29%.
