The little Sumba hawk-owl (Ninox sumbaensis ), also known as the little Sumba boobook or least boobook, is a species of owl in the family Strigidae. It is endemic to the Indonesian island of Sumba. Its natural habitat is subtropical or tropical moist lowland forests. It is threatened by habitat loss.


The little Sumba hawk-owl is about 23 cm (9.1 in) long and weighs 90 grams (3.2 oz). The head is grey with fine dark barring and distinctive white eyebrows but an indistinct facial disc. The beak is large and yellow, the eyes are yellow and there are no eartufts. The upper parts are light brown with widely separated, dark wavy markings and the underparts are whitish with fine dark chevrons. The tail is pale reddish-brown with dark barring.

Habits and Lifestyle

Little is known about this bird. Several pairs have been observed in primary and secondary forest but not in the surrounding open terrain where the Sumba boobook hunts. The conservation status of this owl is assessed as being "Endangered" by the International Union for Conservation of Nature as it has a small range, a moderately small total population and is likely to be decreasing in abundance because of forest clearance.
