Ninox ios is apparently restricted to the highlands of Sulawesi,
Indonesia (BirdLife International 2001), where there have been at least five documented records since the collection of the type specimen
in Bogani Nani Wartabone National Park in 1985, including four records from Gunung Ambang Strict Nature Reserve and one record from Lore Lindu National Park (Central Sulawesi) (Mauro 2001, King 2005, Hutchinson
et al. 2006). The record from Lore Lindu National Park greatly extends its known range.
