Physical description Click here for a physical description Australian Owlet-nightjars are the smallest Australian nocturnal birds. Their plumage can have 4 different morphologies (all 4 are possible for the continental race "cristatus"). The four possible morphologies are orange-grey (most of the continent), orange (in the arid inland), dark-grey (in coastal areas) and pale-grey. The front is lighter than the back for all morphologies. The head has a dark stripe along the crown and dark rings around each eye and eye patch. The front can be lightly barred, the back and tail are also lightly barred. Around the dark-grey bill they have prominent "whiskers". The irises are orange-brown; the legs and feet are grey to pinkish-grey.

Taxonomy, classification See Australian Owlet-nightjar at Wikipedia .

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 Australian Owlet-nightjar is available HERE . Apart from Australia, there have been some reports of Australian Owlet-nightjars found in south-western New Guinea. There are two races of Australian Owlet-nightjars. Nominate race "cristatus" populates almost the entire Australian continent. Only in some parts, such as the most arid regions near Lake Eyre, the Nullarbor and the Pilbara, South of the Kimberley (but also the north-eastern corner of the NT, including Arnhemland), they are found only occasionally, when conditions are right for them to find sufficient prey. Race "tasmanicus" is, as the name already indicates, endemic to Tasmania. Australian Owlet-nightjars are usually found in woodland, in particular where there are trees with suitable hollows (usually eucalypts).

Sightings Click here for sighting information Race "cristatus" We first spotted an Australian Owlet-nightjar, race "cristatus", in September 2008 on the western fringes of Mt. Kaputar NP, in Deriah Aboriginal Area, about 30 km East of Narrabri, NSW. Since then we hear them calling there (even during daylight hours) semi-regularly. They are also found by us in various locations in inland NSW. C. Hayne reports that an Australian Owlet-nightjar, race "cristatus", was seen 5 km North of Moree, NSW, on a dead tree close to the Gwydir River in December 2009 and on the Moree Common in April 2014. B. Hensen reports spotting a pair of Australian Owlet-nightjars, race "cristatus", regularly for about a month at St. Albans, NSW, in February 2011, and then again in February 2018. A. Ross-Taylor reports spotting an Australian Owlet-nightjar, race "cristatus", in high-altitude (1000 m) rainforest at O'Reilly's Plateau, Lamington NP, Gold Coast, QLD, in March 2014. B. Hensen reports finding an Australian Owlet-nightjar, race "cristatus", at Casuarina Coastal Reserve, Darwin, NT, in July 2019. In November 2021, P. Brown also found an Australian Owlet-nightjar, race "cristatus", at Casuarina Coastal Reserve, Darwin, NT.

Behaviour

As opposed to various species of nightjars known to us, Australian Owlet-nightjars do perch on shrubs or trees; they use tree hollows for roosting and have not been found by us on the ground yet.
