Ninox fusca
(Vieillot, 1817)

It has a more grey-brown plumage with no red tinge, unlike other subspecies. It has grey streaks on its belly and white spots on its secondaries, inner wing-coverts and nape.[1] It was described by French ornithologist Louis Pierre Vieillot in 1817 as Strix fusca.[3] Austrian ornithologist Carl Eduard Hellmayr noted that it closely resembled the Australian boobook and concluded it was probably a subspecies of the latter,[4] and Mayr classified it as a subspecies in 1943.[5] Genetic and call analysis show it to be markedly divergent to the Australian populations of the Australian boobook, leading Gwee and colleagues to suggest it be reclassified as a separate species.[6] Its calls are shorter and more frequent than the Australian boobook.[7] It was reclassified as a distinct species in 2019.
