Population justification: The population has been estimated at fewer than 1,000 individuals (Ryan et al. 2009). The number of pairs is estimated to be c.400 equivalent to c.800 mature individuals (R. Porter in litt. 2016).

Trend justification: The population was suspected to be stable in the absence of any identified threats (R. Porter in litt. 2010). However it is known to experience declines after cyclones and to be subject to hunting for food. Thus overall the species may be declining (A. Saeed Suleiman in litt. 2016). Further information is required to ascertain the population trend.
