Justification of Red List categoryThis species is restricted to the twin islands of Biak-Supiori but despite the very small distribution the population size is not suspected to approach thresholds for listing as threatened under Criterion C. The previous population size is considered to have been an underestimate. The population is suspected to be declining due to an ongoing slow rate of forest cover loss. The extent of occurrence, only 3,600 km
2, indicates that the species may be at risk, although the population is not severely fragmented and there are parts of the range where the main threat is not believed to apply. But the species occurrence has been negatively impacted by the recent rate of forest loss (M. Halaouate
in litt. 2022). This rate is ongoing, hence a continuing decline in the area, extent or quality of habitat is inferred. In conjunction with the very small extent of occurrence, the species is considered to approach the thresholds for listing as threatened, meeting Criterion B1b(iii) but not a second subcriterion. Accordingly, Biak Hooded Pitta is assessed as Near Threatened.
