Population justification: The population is estimated at 9,360 (10 individuals/km2 [population densiy of Oriental Bay-owl P. badius in BirdLife Population Density Spreadsheet] × 936 km2 [20% EOO]), i.e. within the range 2,500-9,999 mature individuals, and likely to be at the lower end due to specific habitat requirements. This equates to 3,750-14,999 individuals, rounded here to 3,500-15,000 individuals.
Trend justification: This species is suspected to be in decline owing to the continuing destruction and degradation of its habitat. The likely rate of decline, however, has not been estimated.
