Accipiter quartus Balouet & Olson, 1989:7

Gracile goshawk



Taxonomy & Nomenclature

Anderson et. al. (2010) hesitated at accepting the distinctiveness of this taxon based upon the fact that (Balouet & Olson, 1989) did not perform adequate comparisons with other taxa, only using a small sample size when establishing Accipiter quartus:

"Balouet & Olson (1989) described two Accipiter species (Accipiter quartus and A. efficax) on the basis of fossils that were slightly larger than the extant A. haplochrous and A. fasciatus, respectively. Given the intraspecific variability in extant raptor size and taking into account that only a few fasciatus (none from New Caledonia) and few haplochrous specimens were examined, then these determinations are suspect."
