Lateral view of a male Barking Owl; identification of the genders was made by the birds' behaviour - the male is less attached to the nesting hollow and the chick and is therefore more easily spooked; this bird was hustled at the time of the observations by a bunch of Noisy Friarbirds

FEMALE

Near-frontal view of a female Barking Owl; note how Barking Owls have a very inconspicuous fringe around their head to help them focus on sounds made by their prey; instead they have very prominent eyes, which may suggest predominantly visual target acquisition

Breeding information

Breeding season: Jul - Oct Eggs: 2 - 3 Incubation period: 36 days Fledging age: 35 - 42 days

The breeding season depends on geographical latitude. It is from July to September in the north and August to October in the south.

Nest building: Male (female) Incubation: Female Dependent care: Female

While the male may prepare the nest, the female has all the subsequent duties like incubation and caring for the chicks. While the female incubates the eggs and tends to the needs of the hatchlings, the male feeds her. During daytime he will then roost somewhere close to the nest, possibly with prey in one of its talons. As the chicks grow up, about 2 weeks prior to hatching, the female leaves the nest and stays close to the nesting hollow. If there are chicks, both parents will be seen near the nesting hollow, being attentive. The loss of their brood can be diagnosed by a decline in their interest in the nesting hollow.

The single chick of the pair described here hatched in early December 2011, 2 weeks and 4 days after the female had emerged and just after a major rain event. The parents are one of only 2 pairs (out of 28 monitored) known to have successfully bred that year. Many pairs lost their chicks, most likely to goannas.

Nest

"bungobittah", "malunna" = nest [Aboriginal]

Type: Tree hollow Material: No lining Height above ground: 4 - 20? m

If no suitable trees are found, Barking Owls may also use rock crevices.

Entrance to the nesting hollow from which the chick shown above had emerged; the tree in this case is a River Red Gum

Eggs

"boyanga", "booyanga", "derinya", "dirandil", "koomura", "ngampu", "nooluk", "pateena" = Egg; "dirundirri" = eggs [Aboriginal]; "gawu" = eggs [gamilaraay]

Size: 48 x 38 mm Colour: White Shape: Tapered oval

Behaviour

Social behaviour: Territorial Mobility: Sedentary Elementary unit: Solitary/pair

The family of birds shown in photos above is one out of 28 nesting pairs that are being monitored in a joint program by the NSW DPI and NPWS.

Within their territory each pair has various favourite perches, roosts and a small number of potential nesting hollows.

Food, Diet

Adults: Birds, small animals Dependents: Pieces of adults' prey Water intake: None

Like other species of owls, Barking Owls are carnivores. They prey on a mix of small mammals (e.g. gliders), bats (such as microbats) and other birds, up to their own size (e.g. Galahs), which they pick off their roosts while asleep at night.

They take their liquids in the form of blood of their prey.
