Accipiter efficax   (Balouet & Olson)

Greater New Caledonian Goshawk
(Accipiter efficax)

syn. -


New Caledonia: Grande Terre

local name: -

size: male ca. 50 cm / female ca. 60 cm (length)

extinction date: (?)

The Greater New Caledonian Goshawk was described in the year 1989 on the basis of subfossil bones, which were found on the island of Grande Terre, New Caledonia's main island.

The species, whose females may have reached a size of about 60 cm, was slightly larger as, but otherwise probably very closely related to Meyer's Goshawk (Accipiter meyerianus (Sharpe)), the largest extant species of the genus Accipiter, which occurs in the Bismarck Archipelago, on the Moluccas, in New Guinea and on the Solomon Islands.


At the present day New Caledonia harbours two other hawk species, the Brown Goshawk (Accipiter fasciatus vigilax (Wetmore)) and the White-bellied Goshawk (Accipiter haplochrous (Sclater)), both endemic species resp. subspecies of New Caledonia. Strangely, none of these two species seems to be represented by subfossil bones.
