Physical description Click here for a physical description Australian Boobooks are small owls. The exact colour pattern of their plumage depends on race. Races "leucopsis" and "lurida" are the darkest, race "ocellata" has the lightest colouring, while nominate race boobook has intermediate colouring. The colouring ranges from dark-brown via rufous-brown to almost fawn tints with large white patches, especially on the belly and vent. All Australian Boobooks have a conspicuous facial mask, with dark grey-brown circles around both eyes. The irises are yellowish to greyish. The two dark circles are outlined by triangular-shaped lighter areas on both forehead and throat, leading to the overall impression of a figure-8 pattern on the face. The front is brown (see above), with white chevrons, the crown and back are darker brown with white specks. The undertail is greyish-brown with lighter barring. The bill is light-grey. The legs are covered by feathers; the feet are grey. Male Australian Boobooks of all races have paler colours than females. Twitcher's tip Australian Boobooks are distinguished from Barking Owls by their smaller size, darker front and bigger head compared to the size of the body.

Range, habitat, finding this species Click here for information on habitat and range The overall distribution of this species can be assessed, and specific locations where birds have been spotted can be found, based on individual sighting reports submitted by birdwatchers to ebird.org . The global distribution of the Southern Boobook is available HERE . Southern Boobooks are found in Timor Leste, New Guinea, Australia and New Zealand. Australian Boobooks are well-adapted to life in various habitats, including the semi-arid interior of the Australian continent. Consequently, they are found basically everywhere, including Tasmania. Only in the most arid region, North of the Nullarbor to South of the Kimberley (the major deserts in the eastern half of WA), parts of the Lake Eyre Basin and on the SA/QLD border, they are found only occasionally - likely after substantial rainfall, when there is sufficient prey for them to feed on. They do not venture into the Nullarbor. Race "boobook" is found in the western half of QLD, most of NSW (except the north-western corner) and all of VIC. In the rest of the continent, except the major deserts, race "ocellata" is found. Race "leucopsis" populates Tasmania and the islands in the Bass Strait, whereas race "halmaturina" is found only on Kangaroo Island, SA, and the adjacent mainland. Race "lurida" is found only in a small coastal area around Cairns, QLD. Australian Boobooks are usually found in forest, open woodland and scrub.

Sightings Click here for sighting information Race "boobook" We first saw an Australian Boobook, race "boobook", in 2005 where we lived at the time, 20 km South of Narrabri, NSW. They are regularly heard and seen there, and in other parts of the Pilliga scrub, since then. Australian Boobooks, race "boobook", are found by us regularly since the 2007/08 breeding season at Eulah Creek, 20 km East of Narrabri, NSW. C. Hayne reports that Australian Boobooks, race "boobook", are heard and seen regularly in the area of Moree, NSW. C. Charles reports observing a female Australian Boobook, race "boobook", at Bluegum Reserve in Chatswood, NSW, bringing up two chicks in 2008. A. Ross-Taylor reports hearing Australian Boobooks, race "boobook", calling at night at Highland Park, Gold Coast, QLD, in December 2013. R. Plumtree reports spotting an Australian Boobook, race "boobook", at Doctors Flat Road, Ensay, East Gippsland, VIC, in July 2015. Race "halmaturina" J. Thurmer reports spotting an Australian Boobook, race "halmaturina"(?), in Adelaide, SA, in May 2006. Race "ocellata" P. Brown reports finding an Australian Boobook, race "ocellata", at the Goorrandalng Campground, Keep River NP, NT, in September 2020. C. Pears reports seeing an Australian Boobook, race "ocellata", at the Desert Park, Alice Springs, NT, in August 2016.
