Australian Raven
Corvus coronoides
Measuring 46–53 cm (18–21 in) in length with a 100 cm (39 in) wingspan and weighing around the 650 g (1+7⁄16 lb), the Australian raven is Australia's largest species of corvid. The adult Australian raven is an all black-bird with a black beak, mouth and tongue and sturdy black or grey-black legs and feet. The tibia is fully feathered and the tarsus is long, and the feet large and strong. It has white irises. The plumage is glossy with a blue-purple to a blue-green sheen, greenish over the ear coverts, depending on the light. The underparts are not glossy. Voice: The territorial call of the Australian raven is a slow, high ah-ah-aaaah (similar to the near-open front unrounded vowel (IPA:/æ/)) with the last note drawn out. It uses this call to communicate with other Australian ravens in the area. When giving this call, the species has a horizontal posture, holding its head forward and body parallel to the ground, while perched on a prominent position.

Torresian Crow
Corvus orru
The Torresian crow is a large corvid, about the same size (48–53 cm in length) as the Eurasian carrion crow but with a more robust bill and slightly longer legs. The plumage of the Torresian crow is glossy black on the back and dull black on the breast with inconspicuous throat hackles. Its tail is broad and has a distinctive square-shaped tip. Its bill is dark grey and about the same length as the head. The legs and feet are a similar dark grey color with pink foot soles. The Torresian crow has the typical white iris of the other Australasian Corvus species with a fine, blue eye-ring. Voice: Their voice is quite different from the Australian raven: whilst the more standard loud penetrating Australian raven/crow call "Fark! Fark!" may occur there is often a more nasal, metallic clattering "uk-uk-uk-uk-uk" or sometimes an "ok-ok-ok-ok" or "Ar-ar-argh", sometimes with an upward inflection, somewhat like a cat meow.
