Monotypic species


Members of the genus Ninox are hawk owls, ranging from small to large, with rounded heads without ear-tufts. They have long, pointed wings and a long tail. The nostrils are forward facing on an enlarged cere in an indistinct facial disk. There are at least 20 species in this genus, from Siberia through much of the Pacific rim, South-east Asia and Australasia.

Physical charateristics

Small, brightly coloured hawk-owl. Uniform rufous-chestnut but for whitish scapular spots, whitish feather shafts on underparts, indistinct darker scalloping to lower underparts, and narrow, darker bars on retrices. Lacks any facial patterning. Similar spp. Speckled Hawk-owl N. punctulata, Brown Hawk-owl N. scutulata and Ochre-bellied Hawk-owl N. ochracea are larger with more prominently patterned faces. N. punctulata is spotted white on upperparts and barred white on underparts, N. ochracea and N. scutulata are dark brown, the former with paler yellow-ochre lower underparts, the latter with brown-streaked white underparts

Australasia : North Sulawesi. Ninox ios is apparently restricted to the highlands of Sulawesi, Indonesia, where there have been only four confirmed records, three from the Minahasa peninsula and a recent record from Lore Lindu National Park (Central Sulawesi). The latter record greatly extends its known range.


The four known records are from forest (between 1120 m and 1700 m), and it is assumed that the species is sympatric with, but probably at higher elevations than, the Ochre-bellied Hawk-owl N. ochracea.

Feeding habits

Observations and comparison with owlet-nightjars aegothelidae suggests that the species feeds predominantly upon flying insects by conducting short sallies from exposed branches

Assessment of the status of this species is hampered by its considerable obscurity. Given its apparent rarity and the continuing loss and degradation of forest habitat on Sulawesi, it seems reasonable to surmise that its population is small and declining, qualifying it as Vulnerable.
A collected specimen of this bird
from the Dumoga Bone (now Boga-Nani Wartabone) National Park area was initially
confused as rufous morphs of another known sympatric owl, the Ochre-bellied Hawk-
Owl Ninox ochracea until thorough work, again by Rasmussen proved otherwise.
