Population justification: The current population is thought to be around 120 breeding pairs, equating to 240 mature individuals and roughly 360 individuals in total (R. Watson in litt. 2010).
Trend justification: Recent evidence has suggested that the population is stable, and may have been stable for some time (Johnson et al. 2009, R. Watson in litt. 2010). However, the southern portion of the species's range appears to have contracted and it has disappeared from the SW coast since 2005/2006 (L.-A. Rene de Roland in litt. 2011, Safford and Hawkins 2013). These observations add weight to the suspicion that the species's population is negatively affected by the on-going threats of habitat conversion and persecution. On this basis it is suspected to be undergoing a moderate decline.
