The little crow is a highly sociable species that often forms large flocks, sometimes numbering into the thousands (2) (3). This species is quite agile in flight, and flocks can sometimes be seen performing tumbling acrobatics in the air. The little crow can be rather bold around humans, even attacking human intruders during the breeding season (3).
An omnivorous species, the little crow feeds mainly on insects and other invertebrates, although it also takes small lizards, birds, eggs, mammals and frogs, and will also eat seeds, fruit and occasionally nectar. The little crow may scavenge on rubbish dumps and sometimes feeds on carrion (2) (3). Most foraging takes place on the ground in open habitats, but the little crow also takes food from vegetation, and often patrols roads, paddocks, rubbish dumps and towns in search of carrion and refuse (2).
The little crow is semi-nomadic, with adult breeding pairs only remaining resident in an area for the duration of the breeding cycle. After breeding, both young birds and adults form mobile flocks that congregate at food sources and may move over large distances, sometimes travelling to areas outside of the main breeding range (2) (3).
The breeding season of the little crow varies depending on the location, and breeding often occurs opportunistically after rainfall (2) (3). In southern Australia, breeding typically occurs from July to October, and sometimes from March to May, while in northern Australia it may occur from January to September (2). The little crow usually breeds in small, loose colonies (3).
The nest of the little crow is usually built in a tree, a shrub, an artificial structure such as a utility pole, or even occasionally on the ground. A bulky structure made of twigs, the nest is lined with bark, grass, feathers, wool or hair, and often has a layer of mud or clay beneath the lining (2) (3).
The little crow usually lays a clutch of 4 to 6 eggs (2) (3), which the female incubates for 16 to 18 days. Both adults feed the chicks, and the young birds leave the nest at around 29 to 31 days old. After remaining in the vicinity of the nest for a few days, the family leaves the nesting area and joins a flock. The little crow first breeds at around three years old (2).
