Population justification: Estimated in 1993 to number c.5,000 individuals (Lambert et al. 1993), not all of which will have referred to mature individuals. Although there is no more up to date estimate, declines are only suspected to have been relatively slow in the past three decades such that there are probably still 4,000-5,000 birds. Accordingly, the number of birds is set to 4,000-5,000, of which c. 3,000-4,500 are thought to be mature. Assuming the species is equally distributed across areas of suitable habitat, the largest subpopulation probably numbers c. 1,001-2,000, in the Katanglad/Kalatungan Mountain range.

Trend justification: There are no direct data available from which to determine population trends for this species. Nonetheless, it is suspected to be declining chiefly due to habitat loss and degradation, and perhaps very locally trapping for the pet-trade (although Prioniturus racquet-tails are notoriously difficult to keep in captivity). Over the past three generations (13.2 years: 2011-2024), forest cover loss in this species' geographic and elevational range decreased by c.3% (Global Forest Watch 2024, based on data from Hansen et al. [2013] and methods therein), although this does not account for additive impacts of selective logging and the removal of hollow-bearing trees on which this species depends for nesting. In the absence of detailed information on the extent of forest modification, a rate of decline is therefore not estimated, but that the species is declining is strongly suspected.
