The morepork, also called the ruru or Tasmanian spotted owl, is a small brown owl found throughout New Zealand and Tasmania. Described by Johann Friedrich Gmelin in 1788, it was for many years considered to be the same species as the Australian boobook of mainland Australia until 1999. Its name is derived from its two-tone call. Four subspecies of the morepork are recognized, one of which is extinct and another that exists only as a hybrid population. The bird has almost 20 alternative common names, including mopoke and boobook—many of these names are onomatopoeic, as they emulate the bird's distinctive two-pitched call.

The northern boobook belongs to the family Strigidae and is a raptorial owl endemic to eastern and southern countries of Asia. The species was considered, until recently, a conspecific of Ninox scutulata or brown boobook, a species of similar distribution encompassing 11 subspecies. The species currently includes two subspecies, the migrant Ninox japonica japonica and the non-migrant Ninox japonica totogo. Despite being considered as the most common breeding owl in Japan, little research has been conducted on the species and subspecies and the taxonomic classification of N.j.togoto and N.j.japonica has been a subject of debate. There are no indications of significant decline in northern boobook populations and therefore, its conservation status has been classified as least concern by the IUCN Red List.
