Morepork Synopsis of Birds", but did not give it a binomial name. German naturalist Johann Friedrich Gmelin described the morepork in 1788. "Morepork" has been designated the official name by the International Ornithological Committee. Both Gerlof Fokko Mees and Ernst Mayr regarded the taxonomy of the boobook owl as extremely challenging, the latter remarking in 1943 that it was "one of the most difficult problems I have ever encountered". In his 1968 book "Nightwatchmen of the Bush and Plain", Australian naturalist David Fleay observed that the boobooks from Tasmania more closely resembled those of New Zealand than those from mainland Australia,
Southern boobook Australia", Gould recognised three species, all of which he placed in the genus "Spiloglaux": "S. marmoratus" from South Australia, "S. boobook", which is widespread across the Australian mainland and Tasmania, and "S. maculatus" from southeastern Australia and Tasmania. Meanwhile, in India, English naturalist Brian Houghton Hodgson had established the genus "Ninox" in 1837, and his countryman Edward Blyth placed the southern boobook in the new genus in 1849. "Southern boobook" has been designated the official name by the International Ornithological Committee. The common name comes from the two-tone call of the bird, and has also been transcribed as "mopoke". William
