Population justification: The population is estimated to number 250-999 mature individuals based on an assessment of known records, descriptions of abundance, and the fact that only a proportion of the estimated Extent of Occurrence is likely to be occupied.

Trend justification: During eight visits to Manus between 2002 and 2005, the species was found to be absent from areas close to where it had previously been recorded and at most sites individuals were either absent or present at very low densities (A. Mack in litt. 2012). Interviews with local people during these visits also found that many were unfamiliar with the species (A. Mack in litt. 2012), although such interviews should be interpreted with caution. About 2% of forest on Manus was lost plus 7% logged between 2002-2014 (Bryan and Shearman 2015). However, the number of individuals around Rossun village may be fairly stable (A. Mack in litt. 2012, G. Dutson in litt. 2013). On the basis of this information, the species is suspected to be undergoing a moderate population decline.
