Australian Birds

Torresian Crow
Corvus orru
(Viewing 4 of 10 photos)

Click to listen to sound samples Torresian Crows are birds of Australia's "northern half", extending south to around Newcastle (Hexham Swamp) on the east coast and to near Carnarvon in W.A. Further inland they occasionally reach Norseman in W.A. and since the advent of irrigation and cotton farming in northern N.S.W., breeding birds now occur at Narrabri. In Brisbane, Cairns and Darwin Torresian Crows are the only corvid - in Brisbane in particular, they have become commensal and are regarded as a nuisance because of the noise generated by roosting flocks. Although essentially a "tropical" species, they have become adapted to arid inland Australia, mainly in areas where there is permanent water. Over a large area of Queensland they occur alongside Australian Ravens (mainly west of the Great Divide) but these two species are easily separated on call. In much of the arid zone and north-western Australia, Little Crows also occur and apart from differences in calls, Torresian Crows and Little Crows are not easy to separate. Certainly size is not a reliable guide. In parts of NE Qld. (such as near Charters Towers) some very small Torresian Crows occur and these give rise occasionally to incorrect reports of Little Crows well out of their known haunts. On the Barkly Tableland there are birds with a small body but a large bill that are known to breed after the wet season.

A quick check - to tell a crow from a raven look at the bases of their body feathers, see pics 692211 & 692212.
