The Barn Owl is found throughout Australia. Its distribution is limited only by habitat and food availability. Habitat: By day the Barn Owl roosts in hollow logs, caves or dense trees, and is usually seen alone or in pairs. A Barn Owl at Cravens Peak in Queensland. Photo Jane Blackwood. Owls are versatile and live in a range of habitats including snowy, mountainous regions; deserts; open wet forests and rainforests; woodlands and grasslands across the world. In Australia, owls are found in every state and territory. Feeding and diet Barn Owls feed mostly on small mammals, mainly rodents, and birds, but some insects, frogs and lizards are also eaten. One of the more favoured foods is the introduced House Mouse, Mus musculus. Barn Owls hunt in flight, searching for prey on the ground using their exceptional hearing. Barn owls are the most widespread of all owl species, and are found on every continent except Antarctica. In the Americas, barn owls occur in suitable habitat throughout South and Central America, and in North America as far north as the northern United States and southwestern British Columbia. Found in northern and eastern parts of Australia, the owl regularly lives in localized pairings. However in places where prey is abundant, loose colonies may occur. A powerful Tyto owl, the Australian masked owl — a Tasmanian sub-species, is the largest Tyto owl in the world. Its plumage is highly variable.

HANGING OUT - ROOSTING At the end of a day or night spent hunting, owls return to a resting place, called a roost. Most owls roost alone, or near a nest during the breeding season. However, there are a few species that roost communally, or share a roosting area with other individuals of the same species.

Calls. Barn Owls don't hoot the way most owls do; instead, they make a long, harsh scream that lasts about 2 seconds. It's made mostly by the male, who often calls repeatedly from the air. Males use it to invite a female to inspect a nest site, and females use it to beg for food from the male.

They also perch on posts or other low perches listening for prey in darkness, locating it by ear. As with all owls, Barn Owls "echo-locate" prey -- changing the position of their head until they zero-in on the exact location of a sound (such as the squeak of a mouse or the rustle of their prey's feet).

All owls are predators; they depend on other animals for food. However, very few predators feed on owls (except sometimes other owls). In fact, owls often eat other predators, such as weasels, bats, shrews and insect-eating birds. Therefore, owls hold a position at the top of the food chain.
