Dwarf Sparrowhawk Accipiter nanus

Justification
This species is classified as Near Threatened because, although it is very poorly known and difficult to identify, the paucity of records suggests that it is uncommon and has a moderately small population, which is suspected to be in decline owing to continued habitat loss. However, the montane forests it inhabits are relatively secure and a better understanding of its status may lead to it being downlisted in the future.

Taxonomic source(s)
del Hoyo, J.; Collar, N. J.; Christie, D. A.; Elliott, A.; Fishpool, L. D. C. 2014. HBW and BirdLife International Illustrated Checklist of the Birds of the World. Barcelona, Spain and Cambridge UK: Lynx Edicions and BirdLife International.

Distribution and population
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.

Population justification
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.

Ecology
It inhabits mountain and hill forest at 550-2,250 m (Ferguson-Lees and Christie 2001).

Threats
Forest loss in the lower-lying areas of Sulawesi has been extensive in recent decades and has probably caused this species to decline.

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.
