Justification of Red List Category
This species is classified as Near Threatened because it is confined to one small island on which habitat degradation may be causing a moderate decline.
The global population numbers c.2,400-4,000 pairs (V. Chartendrault and N. Barré in litt. 2007), best placed precautionarily in band 2,500-9,999 individuals. This equates to 1,667-6,666 mature individuals, rounded here to 1,500-7,000 mature individuals.
There are no data on population trends; however, habitat degradation is suspected to be causing a slow to moderate decline.
Accipiter haplochrous is endemic to New Caledonia (to France) where it is fairly common throughout. It is distributed from the far north (Manjelia) to the far south at Goro. Its area of occurrence is therefore c.12,000 km2, which if each pair requires 3-5 km2, equates to a population of c.2,400-4,000 pairs (V. Chartendrault and N. Barré in litt. 2007).
It appears to be widespread in humid forest but occurs at lower densities in degraded forest and savannah where it coexists with Brown Goshawk A. fasciatus. It is not shy and often found close to human habitation (V. Chartendrault and N. Barré in litt. 2007).
Despite legal protection, a few are killed around inhabitated areas, as it sometimes kills domestic chickens, and habitat loss and degradation are further threats (Vuilleumier and Gochfield 1976, Stokes 1980, Thiollay 1993, Ekstrom et al. 2000). However, it is assumed that it is not undergoing any significant continuing decline.
