Physical description Click here for a physical description Eastern Barn Owls are small to medium-sized owls. They have a conspicuous, heart-shaped white facial mask. The front is white with sparse greyish specks, the back is greyish-rufous with white specks. The eyes are black and the bill is light-grey. The legs are mostly covered with feathers, while the feet are grey. Female Eastern Barn Owls have a slightly lighter back than males and more speckles on the front. Twitcher's tip They are distinguished from Eastern Grass Owls by their much lighter colours, both front and back. In-flight the most conspicuous distinguishing criterion is the length of the legs, which in Eastern Barn Owls trail end near the tip of the tail.

Taxonomy, classification See Eastern Barn Owl at Wikipedia . Click here for classification information Many sources still list the Eastern Barn Owl as race "delicatula" of the "Barn Owl" (Tyto alba).

Range, habitat, finding this species Click here for information on habitat and range The overall distribution of this species can be assessed based on sighting reports submitted by birdwatchers to ebird.org . The global distribution of the Eastern Barn Owl is available HERE . Apart from Australia, Eastern Barn Owls are also present in Timor Leste, parts of eastern Indonesia, the Solomon Islands, Vanuatu and New Caledonia. Barn Owls are a global genus of birds that are found on various continents. Tyto delicatula, the Eastern Barn Owl found in Australia, is an endemic breeder. They are mostly found in the eastern half of the continent, except western QLD, plus basically all of the NT. They breed in the South-East of the continent, in the southern and eastern hill ranges and the Murray River catchment. Outside their breeding season they are also found along the West coast of the continent and occasionally, when conditions are right for them to find sufficient prey, anywhere in between, including the most arid parts of the continent. Barn Owls are also found in Tasmania, mostly on the eastern side. Eastern Barn Owls can be found in a variety of habitats, from open grassland (when hunting) to open woodland and riparian woodland, where there are trees with suitable hollows or caves. They adapt well to the presence of humans and can be found roosting and/or nesting e.g. in barns or sheds.

Sightings Click here for sighting information An Eastern Barn Owl was first seen by us in Australia in July 2009, on a roadside reflector post just East of Bauhinia, QLD, without a chance to take a photo. M. Windeyer reports spotting an Eastern Barn Owl occasionally in the township of Gilgandra, NSW. A pair of birds was seen regularly by us over an extended period in 2011, 15 km East of Narrabri, NSW. Another pair was spotted 15 km North-East of Narrabri. Occasionally, Eastern Barn Owls are heard calling at Eulah Creek, 20 km East of Narrabri. A family of at least three birds was spotted in a River Red Gum at Gurley Creek, about 10 km East of Gurley, NSW, in December 2013. P. Spark's help with these observations is most gratefully acknowledged. C. Hayne reports occasionally seeing Eastern Barn Owls hunting off road signs and reflector posts in the area of Moree, NSW. Two Eastern Barn Owls were seen by us hunting by a roadside about 20-30 km East of Bellata, NSW, in June 2015. M. Eaton reports spotting an Eastern Barn Owl in Anstead, QLD, in April 2018. M. Mearns found an Eastern Barn Owl along the Bedouri to Boulia Highway, western QLD, in September 2019. The calls of an adult Eastern Barn Owl with a begging juvenile were recorded by us in woodland between Eulah Creek and Deriah Aboriginal Area, 30 km East of Narrabri, NSW, in December 2019.

Sex unknown

Frontal view of two Eastern Barn Owls; it is unknown to us whether this is a pair or an adult with a dependent juvenile; although the bird on the right appears to be taller than the one on the left, the one on the left may be hunched - in a pair the more heavily speckled bird would be the female, which is normally also larger
