Description
Measuring 46–53 cm (18–21 in) in length with a 100 cm (40 in) wingspan and weighing around 650 g, the adult Australian Raven is an all black bird with black feet and beak and a white iris. The plumage is glossy with a blue-purple to blue-green sheen, greenish over the ear coverts, depending on light. The underparts are not glossy. Its throat feathers (hackles) are longer than those of other species. It can be distinguished from the two species of crow occurring in Australia by the grey base of the feathers, which is white in the latter species. Juveniles resemble adults, but have dark eyes, shorter throat hackles, and sometimes have a pink fleshy gape.
The territorial call of the Australian Raven is a slow, high ah-ah-aaaah with the last note drawn out. It will use this call to communicate with other Australian Ravens in the area. The five Australian species are very difficult to tell apart, with the call being the easiest way to do so.

Famous quotes containing the word description:
“The Sage of Toronto ... spent several decades marveling at the numerous freedoms created by a “global village” instantly and effortlessly accessible to all. Villages, unlike towns, have always been ruled by conformism, isolation, petty surveillance, boredom and repetitive malicious gossip about the same families. Which is a precise enough description of the global spectacle’s present vulgarity.”
—Guy Debord (b. 1931)
“He hath achieved a maid
That paragons description and wild fame;
One that excels the quirks of blazoning pens.”
—William Shakespeare (1564–1616)
“The great object in life is Sensation—to feel that we exist, even though in pain; it is this “craving void” which drives us to gaming, to battle, to travel, to intemperate but keenly felt pursuits of every description whose principal attraction is the agitation inseparable from their accomplishment.”
—George Gordon Noel Byron (1788–1824)
