Population justification: The population size of this species is unknown. Approximately 137 km2 of forest was left in this species' range in 2020 (Global Forest Watch , using data from Hansen et al.  and methods disclosed therein). The population was previously estimated to number 250-999 mature individuals, however was described as abundant by Diamond et al. (2009) and it occurs in primary and secondary forest as well as shaded gardens. eBird (2021) data appear to corroborate this, with a single checklist documenting 10 individuals on a 2-mile walk, more than any other forest bird (but also, given its loud vocalisations, presumably it is among the most detectable). Given the high densities recorded in other Tanysiptera (Bell , for example, recorded densities of up to 500 individuals/km2 of T. galatea, although this is probably exceptional) and the qualitative descriptions of its abundance, it is difficult to estimate the population size of this species; however, the population is considered very unlikely to number fewer than 1,000 mature individuals.
Trend justification: Although the species persists in traditional gardens, it is apparently most common in closed-canopy primary and secondary forest. Tree cover loss in this species has been minimal (equivalent to c.2% over the past three generations; Global Forest Watch , using data from Hansen et al.  and methods disclosed therein); however, there are additional reports of selective logging (see Diamond et al. 2009, Beehler and Pratt 2016) indicating degradation that is precautionarily thought to be causing a slow decline in mature individuals. The rate of this decline however remains unquantified.
