Population justification: This species was split from the Philippine Pitta Erythropitta erythrogaster in 2016. Based on a population density estimate for this congener, of 2.8-30 individuals/km², and that only a proportion (c.20%) of the mapped range is likely to be occupied, the population size is inferred to be 308-3,300 individuals. This is roughly equivalent to 206-2,211 mature individuals.

Trend justification: The population is suspected to be in decline owing to habitat loss (Dutson 2011). Data from Global Forest Watch (2021) suggests that the rate of decline is likely <10% over three generations (12.2 years [Bird et al. 2020]).
