Southern boobook age. Brushtail possums ("Trichosurus" spp.) and introduced cats and rats raid the nests for nestlings and eggs, and raptors such as the brown goshawk ("Accipiter fasciatus"), grey goshawk ("Accipiter novaehollandiae"), Australian masked owl ("Tyto novaehollandiae"), and probably powerful owl ("Ninox strenua") seize young birds. Juvenile southern boobooks are at greater risk after bushfires and have perished after being tangled up in dodder ("Cassytha") or bidgee-widgee ("Acaena novae-zelandiae"). The southern boobook generally preys on mice, insects, particularly nocturnal beetles and moths, and birds the size of a house sparrow ("Passer domesticus"). A higher proportion of its diet is invertebrates compared with
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
