Geographic Range [top]
Range Description: Accipiter nanus is restricted to Sulawesi (uncommon to rare) and Buton (rare), Indonesia. It has been recorded from very few localities, although its similarity to the Vinous-breasted Sparrowhawk A. rhodogaster has possibly resulted in it being under-recorded.
Countries occurrence:
Native:
Indonesia
Additional data:
? Continuing decline in area of occupancy (AOO): Unknown

Population [top]
Population: The global population size has not been quantified, but the species is described as uncommon to rare (del Hoyo et al. 1992).
Trend Justification: A population decline, as yet unquantified, is suspected on the basis of rates of habitat loss and degradation.
Current Population Trend: Decreasing
Additional data:
? Number of mature individuals: Unknown ? Continuing decline of mature individuals: Unknown
? Extreme fluctuations: No ? Population severely fragmented: No
? Continuing decline in subpopulations: Unknown
? Extreme fluctuations in subpopulations: No ? All individuals in one subpopulation: No
Habitat and Ecology [top]
Habitat and Ecology: It had previous considered a species of mountain and hill forest above 550 m (Ferguson-Lees and Christie 2001), however on Buton the species has been recorded down to sea level (Martin et al. 2012).
Systems: Terrestrial
Continuing decline in area, extent and/or quality of habitat: Unknown
Generation Length (years): 7.2
Movement patterns: Not a Migrant
Threats [top]
Major Threat(s): While the majority of forest loss on Sulawesi has occurred in the lower-lying areas, loss and degradation has also taken place in mid to relatively high altitudes and is considered likely to have caused this species to decline.
Conservation Actions [top]
Conservation Actions: Conservation Actions Underway
CITES Appendix II.
Conservation Actions Proposed
Survey to assess the size of the population. Research its tolerance of logged forest. Protect large areas of unlogged forest in areas where it occurs.
