Cinnabar boobook Cinnabar boobook The cinnabar boobook ("Ninox ios") also known as the cinnabar hawk owl, is a hawk owl endemic to the island of Sulawesi, Indonesia. It was described as a new species to science by American ornithologist Pamela C. Rasmussen in 1999 based on a single specimen collected by Frank Rozendaal from Bogani Nani Wartabone National Park on Minahassa Peninsula, northern Sulawesi, in 1985. Subsequently, it has also been observed in Lore Lindu National Park in central Sulawesi, greatly expanding the known habitat range. The cinnabar boobook is small (total length 22 cm or 8.5 in) and has a relatively
Southern boobook to "N. connivens". Genetic and call analysis show the Christmas boobook ("N. natalis") to be very close to the Australian populations of the southern boobook, leading Gwee and colleagues to suggest it be reclassified within this species. Gwee and colleagues found that boobook populations on larger mountainous islands were more distinct from Australian stock, while those on flatter smaller islands were much more similar, suggesting that these locations were colonised much more recently after previous populations had become extinct. Eleven subspecies of "Ninox boobook" are recognised in version 7.3 of the IOC World Bird List, published in July 2017: The
