The Australian masked owl (Tyto novaehollandiae ) is a barn owl of Southern New Guinea and the non-desert areas of Australia.
Other common names have been used for this species in the past. For example:
Nocturnality is an animal behavior characterized by being active during the night and sleeping during the day. The common adjective is "nocturnal",...

starts withBrown feathers surround a white, heart-shaped mask. Their dorsal plumage is brown, aside from light gray spots on the upper back. Their front is white with brown spots. Their eye color varies from black to dark brown. Females are darker shaded and larger than males.
Male masked owls' weights ranges from 420 to 800 g (0.93 to 1.76 lb), while females are typically much larger ranging from 545 to 1,260 g (1.202 to 2.778 lb). Length ranges between 330 to 410 mm (13 to 16 in) for males and 390 to 500 mm (15 to 20 in) for females. Wing span is up to 1,280 mm (50 in) for southern female masked owls. Masked owls follow the typical pattern of birds from the tropics being much smaller than birds from temperate regions. In this instance, Tasmanian masked owls are the largest and the largest of the entire barn-owl family, among the species in the family only the greater sooty owl appears to heavier than the Australian masked owl on average but the Tasmanian species is rather larger and heavier even than the greater sooty owl. The mean weight of the nominate subspecies was found to be 476 g (1.049 lb) in males and 630 g (1.39 lb) in females while in Tasmania, mean weighs for males were 632 g (1.393 lb) and for females were 845 g (1.863 lb).
The Australian masked owl inhabits timbered areas, often with a shrub understorey. In Australia they are seldom found more than 300 km inland. They roost and nest in large tree hollows near foraging areas. They are nocturnal and their prey includes rodents, small dasyurids, possums, bandicoots, rabbits, bats, birds, reptiles and insects. Foraging is primarily for terrestrial prey, however some prey is taken from the trees or in flight. The population of the Australian masked owl on the mainland is declining and several states have this owl on the Species Conservation Status list. They are territorial and may remain in the same area once they have established a breeding territory. A 2020 case study done using radio telemetry showed that the “home” range of these owls might be as large as 19-23 km2, but this data remains ambiguous due to the small sample size.
They breed when conditions are favorable which can be any time of the year. The nest is usually built in hollow trees with soil, mulch or sand. Some populations are known to use caves or rock crevices for nesting and roosting. The female lays two or three eggs and incubates them while the male hunts for food. The young are white or off white when they first develop feathers. They can leave the nest at two to three months of age but return to be fed by the parents for another month before going on their own.
The population of the Australian masked owl on the mainland is declining and several states have placed this owl on the Species Conservation Status list.
In Victoria (Australia), the masked owl is a listed threatened bird, and an Action Statement has been prepared under the Flora and Fauna Guarantee Act 1988. In New South Wales, the masked owl is scheduled as Vulnerable under the Biodiversity Conservation Act (2016).
