Cinnabar Hawk Owl is small and has a relatively long tail and narrow pointed wings. The known four records of the species indicate it is a nocturnal forest dwelling species living at mid-altitudes . Otherwise very little is known of its habits. Based on morphological similarities with owlet-nightjars, Rasmussen suggests Cinnabar Hawk Owl may be an insectivore and prey on invertebrates in flight.
The Cinnabar hawk-owl is classified as Vulnerable (VU), considered to be facing a high risk of extinction in the wild.
The type specimen of Cinnabar Hawk-Owl was obtained in 1985 by Frank Rozendaal in what is now known as Bogani Nani Wartabone National Park. At that time it was believed to be a rufous morph of Ninox ochracea. In a recent paper, Robert Lee and Jon Riley report on a second find of this new owl, in Gunung Ambang Nature Reserve, North Sulawesi, at an altitude of 1420 m. More
