Population justification: The global population size has not been quantified, but the species is reported to be generally common on Halmahera and Bacan (Frith and Beehler 1998).  A survey of the two National Parks Aketajawe-Lolobata estimated a population of 24,128 - 61,553 individuals within the 1,673 km² protected area (Bashari 2012).

Trend justification: The population is suspected to be in decline owing to on-going habitat loss (Frith and Beehler 1998).  A remote sensing study tracked forest loss in the Northern Maluku Endemic Bird Area between 1990 and 2003, and projected rates of deforestation over the next three generations for restricted range bird species found in this region (Vetter 2009).  This study estimated the rate of forest loss within the species's geographic and elevation range to be c.8.4% between 1990 and 2003, and projected the loss of c.16.6% of forest in its range over the next three generations (estimated at 23.7 years) (Vetter 2009).
