Cinnabar boobook

The Cinnabar boobook, scientifically known as Ninox ios, is a small hawk-owl species that is endemic to the island of Sulawesi in Indonesia. It was first described as a new species in 1999 by ornithologist Pamela C. Rasmussen, based on a specimen collected in northern Sulawesi. The species' name derives from the Greek word 'ios,' meaning 'rust,' a reference to its prominent chestnut plumage.

Morphology and Habitat

This owl measures approximately 22 cm in total length. Its plumage is predominantly chestnut-colored, distinguished by white markings on the scapulars and paler coloration on its underbelly. The Cinnabar boobook possesses distinctive pink orbital skin and bright yellow irises. It is a forest-dwelling species, typically found in mid-altitude regions ranging from 1,100 to 1,700 meters above sea level. Observations indicate it spends most of its time in the middle or upper canopy of the forest.

Ecology and Behavior

The Cinnabar boobook is a nocturnal hunter, meaning it is primarily active during the night. Its diet consists of insects, which it catches in flight. A notable behavioral trait is its capability to hover for several seconds while pursuing prey. The vocalization of the Cinnabar boobook has been described by researchers as a "dry, nasal, hissing, shriek," bearing a resemblance to the calls of a barn owl.

Distribution

Records of the Cinnabar boobook have been documented in several locations across Sulawesi. These include Bogani Nani Wartabone National Park on the Minahassa Peninsula in northern Sulawesi, where the initial specimen was collected. It has also been observed in Gunung Ambag Nature Reserve, also in northern Sulawesi, and in Lore Lindu National Park, situated in central Sulawesi.
