Australian Raven
Crow
The other six members of the Corvidae family.
There are three species of raven in Australia, and three crows. Ravens are generally bigger than crows, but other differences - e.g. range, calls - are more reliable for identifying which species is which.
Identification
Australian Ravens are black with white eyes in adults. The feathers on the throat (hackles) are longer than in other species, and a bird tends to extend these when calling, while holding its head and body in a horizontal position. Australian Ravens are usually seen in pairs. Another aid to identification of this species is the absence of wing-flicking while calling. Young birds resemble the adults, but have dark eyes, shorter throat hackles and often the presence of a pink, fleshy gape. This species is sometimes called a crow.
Habitat
The Australian Raven is found in all habitat types, with the exception of the more arid areas of Western Australia.
Distribution
The Australian Raven is found in eastern, southern and central Australia.
Feeding and diet
The Family Corvidae has a wide-ranging diet that may consist of grains, fruits, insects, small animals, eggs, refuse and carrion; however, the Australian Raven is mainly carnivorous.
Communication
The territorial call is a slow, rather high 'ah-ah-ah-aaaah' with the last note drawn out.
Breeding behaviours
Australian Ravens construct a large untidy nest, normally consisting of bowl or platform of sticks, lined with grasses, bark and feathers. Both sexes construct the nest and feed the young. The incubation of the eggs is performed solely by the female, and only one brood is raised in a year.
