Cinnabar Boobook

The cinnabar boobook (Ninox ios) is a small owl in the family Strigidae, endemic to Sulawesi in Indonesia. It inhabits primary and mature secondary forest at low to mid elevations on the island, typically in humid lowland to foothill forest. Like other boobook owls, it is nocturnal, roosting in dense foliage during the day and hunting small vertebrates and invertebrates by night. The cinnabar boobook has rich rufous-brown upperparts and a distinctive reddish coloration that gives the species its evocative common name. The species is classified as Least Concern by the IUCN, with populations considered stable within its Sulawesi forest range. Sulawesi is a biogeographically remarkable island at the intersection of the Asian and Australian faunal zones, hosting a high proportion of endemic species. The island's forests face ongoing pressure from logging, mining, and agricultural encroachment, but the cinnabar boobook's adaptability to secondary forest provides some resilience. The species is entirely restricted to Sulawesi and does not occur in Europe; any database records listing Norway are data entry errors. The genus Ninox comprises the boobook owls of Australasia and Southeast Asia, with numerous island endemic species across Indonesia, the Philippines, and the Pacific islands.
