Morepork they emulate the bird's distinctive two-pitched call. It has dark brown plumage with prominent pale spots, and golden-yellow eyes. It is generally nocturnal, though is sometimes active at dawn and dusk, retiring to roost in secluded spots in the foliage of trees. The morepork feeds on insects and small vertebrates, hunting by pouncing on them from tree perches. The International Union for Conservation of Nature has assessed the morepork as being of least concern on account of its large range and apparently stable population.

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
