 (C. coronoides) as a distinct species.

Description

Some of the differences, between the two species, are that the Little raven: on average a little smaller than the Australian Raven (48–50 cm in length), though sizes do overlap between both species; the beak is slightly smaller and more curved, calls are shorter and the throat bulges out less while calling. This bird is a somewhat more sociable species by comparison, often forming large flocks that roam freely over wide areas in search of food. The range of the Little raven does overlap the range of the Australian Raven, but the Australian Raven's range extends further.

Diet

Little Ravens tend to eat rather more vegetable matter than C. coronoides and to feed mainly on the ground, but is probably omnivorous to a similar extent to other Corvus species when opportunity arises.

Nesting

Little Ravens often nest in a loose colony of up to fifteen pairs, with nests few meters apart. They have often been recorded as having several nests within the nesting territory of a single Australian Raven which, presumably due to different food preferences, does not seem to consider them a threat to its own food resources.

The nest is a thin cup of sticks with a layer of bark, grass and wool to create a thick mat. Nests are commonly low to the ground (under 10 meters), often in a forked branch in the outer canopy of a tree.
Juveniles have brown colored eyes until their 3rd year, their eye color changes to white.

Voice

Its call is a harsh, guttural "kar-kar-kar-kar" or "ark-ark-ark-ark". They also do a quick upward flick of both wings with each note.
