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

Formerly, the Australasian figbird was considered as a subspecies of the green figbird and referred to as simply the figbird, a name still commonly used in Australia, where the Australasian figbird is the
