The Australian raven was first described by Nicholas Aylward Vigors and Thomas Horsfield in 1827, in which they reported George Caley's early notes on the species from the Sydney district. Its specific epithet coronoides "crow-shaped" is derived from the Greek corone/κορόνη "crow" and eidos/είδος "shape" or "form".

The Australian raven (Corvus coronoides) is a passerine bird in the crow family native to much of southern and northeastern Australia. Measuring 46�53 centimetres (18�21 in) in length, it has all-black plumage, beak and mouth with white irises. The grey-black legs and feet are well-developed. The upperparts are glossy, with a purple, blue or green sheen. Like those of the other two species of raven in Australia, its black feathers have grey bases. The Australian raven is further distinguished by its prominent throat hackles. Nicholas Aylward Vigors and Thomas Horsfield described it in 1827, its species name highlighting its similarity with the carrion crow (C. corone). Two subspecies are recognised, which differ slightly in calls and are quite divergent genetically. The preferred habitat is open woodland and transitional zones, and it has adapted well to urban environments and is a common city bird in Sydney, Canberra and Perth. An omnivorous and opportunistic feeder, it eats a wide variety of plant and animal material, as well as food waste from urban areas. In eastern Australia its range is strongly correlated with the presence of sheep, and it has been blamed for killing lambs. However, this is very rare, and the raven most often scavenges for afterbirth and stillborn animals as well as lamb faeces. The Australian raven is territorial, with pairs generally bonding for life. Breeding takes place between July and September, with almost no variation across its range. The nest is a bowl-shaped structure of sticks sited high in a tree, or occasionally in a man-made structure such as a windmill or building
