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).
Trend justification: The population is suspected to be in decline owing to on-going habitat loss (Frith and Beehler 1998). A recent study by Vetter (2009) used remote sensing techniques to track the rate and spatial pattern of forest loss in the Northern Maluku Endemic Bird Area between 1990 and 2003, and project rates of deforestation over the next three generations for restricted range bird species found in this region. This study estimated the rate of forest loss within the geographic and elevation range of Standardwing 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 by BirdLife to be c.24 years, based on an estimated generation length of c.7.9 years) (Vetter 2009).
