This speciesis classified as Vulnerable because remote-sensing
data indicate that there has been a dramatic loss of lowland
forest across its range and that it is therefore likely to be
undergoing a rapid population decline. Distribution and
population Ninox odiosa is endemic to the island of New Britain
Papua New Guinea where although it is rather poorly known, it
appears to be not uncommon in suitable habitat. It is suspected
to have declined rapidly in recent years owing to ongoing
clearance of lowland forest (Buchananet al. 2008). The
population is estimated to be in the band 10,000-19,999 mature
individuals, equating to 15,000-29,999 individuals in total,
rounded here to 15,000-30,000 individuals. Buchanan et al.
(2008) calculated the rate of forest loss within the species's
range on New Britain as 33.8% over three generations. Hence,
this decline is expected to continue. It inhabits lowland
rainforest up to 1,200 m. It is thought to tolerate some degree
of habitat degradation. Lowland forest clearance o
