Population justification: The global population size has not been directly estimated. The species has previously been described as locally common (Feare and Craig 1998); however, the species is now rare and hard to locate within its native range in South Sulawesi (A. Banwell in litt. 2019, eBird 2019), and it is suspected that the population is now small. Recorded only infrequently, it appears that the species now occurs at very low densities and is absent from the majority of its former range; based on the likely occurrence areas and suppressed density, the population size is highly unlikely to exceed 10,000 mature individuals. Within Pale-bellied Myna's native range, it is likely that the population exists as a single subpopulation.

Trend justification: The species is now rare and hard to locate, and is known to have been heavily trapped and traded (A. Banwell in litt. 2019), having been 'common' in the 1980s (White and Bruce 1986), and 'quite common' in the 1990s (Holmes and Phillipps 1996). It is therefore assessed as being in decline. The rate of this decline is very difficult to assess as the species was previously included within a complex of several similar Acridotheres mynas, and does not occur in habitats in which ornithological research has been carried out in the region so has not been seen as a taxon of concern. Equally the confused former taxonomic status means that previous market data holds no information that can be definitively assigned to this species. Very large numbers of Javan Myna A. javanicus have been recorded in trade, but it appears highly likely that an unknown (and significant) proportion of these were Pale-bellied Mynas, given the observation of trapping and trading within the species range. Consequently a continuing decline is believed to be occurring, but the rate of this has not been quantified.
