The Australian Boobook (Ninox boobook) is Australia’s smallest and most common species of owl. Often called the ‘Southern Boobook’, ‘boobook owl’, ‘mopoke’ or ‘morepork’, this versatile species is found throughout mainland Australia, Timor, the Sundas and also southern Papua New Guinea. As a result of recent taxonomic changes, the species found on mainland Australian has been named ‘Australian Boobook’ (Ninox boobook). The boobooks found in Tasmania are currently considered a subspecies of Morepork (Ninox novaeseelandiae leucopsis) which is also found in New Zealand.
Australian Boobooks can live in a wide variety of habitats including rainforests, semi-deserts, farmland and even city parks. Despite being common and widespread, they are often hard to see during the day as they generally roost well-hidden in dense foliage.
Listen to Australian Boobook Sounds
The call of the Australian Boobook is one of the most common sounds of the Australian bush at night. Typical calls consist of a double note ‘boo-book’ which can be heard throughout the year. They also make a lower-pitched, rapid call, a grating call which sounds not unlike the call of the Glossy Black Cockatoo (Calyptorhynchus lathami) and less commonly a ‘yeow’ call. Juveniles often make a trilling or hissing-type call which can be heard at the end of the video below.
The video below contains five different call types of the Southern Boobook:
