It is a poorly-known forest-dwelling species, which is rarely seen. Comparison with the closely related Australian Masked Owl indicates it is likely to have large territories, and the population may be smaller than 1000.
The Manus Masked-Owl is classified as Vulnerable (VU), considered to be facing a high risk of extinction in the wild.
Manus Masked-owl is likely to have large territories, with a home-range size of between 0.04-1.8 km2 per pair9. Threats In 1987 80% of vegetation on Manus was estimated to be primary forest6. Large areas of lowland Manus are now logged or under logging concessions and in coastal areas the forest is being eroded by shifting cultivation. More
