Population justification: The population is estimated to number 1,000-10,000 individuals, roughly equating to 670-6,700 mature individuals.
Trend justification: The population is suspected to be in decline owing to on-going habitat destruction (Ferguson-Lees and Christie 2001). A recent sudy by Vetter (2009) used remote sensing techniques to track the rate and spatial pattern of forest loss in the Northern Maluku Endemic Bird Area (EBA) between 1990 and 2003, and project rates of deforestation over the next three generations for restricted range bird species found in this region, with consequent recommendations for category changes on the IUCN Red List. This study estimated the rate of forest loss within the elevation range of Rufous-necked Sparrowhawk in the EBA to be c.18.7% between 1990 and 2003, and projected the loss of c.33.6% of forest in its range in the EBA over the next three generations (estimated by BirdLife to be c.22 years, based on an estimated generation length of c.7.2 years). The species, however, shows some tolerance of habitat modification and occurs in montane areas where forest may be comparatively more secure, perhaps buffering its population against the impacts of deforestation across its range. There is also uncertainty over deforestation rates in parts of the species's range not covered by Vetter's (2009) study, such as Buru and Seram. It is therefore suspected that the species will experience a population decline of 25-29% over 22 years, from 2004 until 2026.
