Physical description Click here for a physical description Together with Australian Ravens, Torresian Crows are the largest Australian corvids (ravens and crows). Their plumage is glossy-black on the back, plain black in front. Their appearance depends mostly on the angle of infalling sunlight. The length of the bill about equals the size of the head. In straight, level flight the tail is wide and straight, with a square-shaped tip. The eyes have whitish irises. The long, straight bill is dark-grey. The legs and feet are also dark-grey, with pink foot soles. Juveniles have fleshy gapes, dark irises and a shorter bill and tail. Twitcher's tip The correct identification of corvids in the field is notoriously difficult. Compared with other Australian corvids, Torresian Crows have the broadest and most square-shaped tail. If visible, e.g. when ruffled by wind, the base of feathers of ravens is grey (while those of crows have white bases). The transition from black to grey is gradual (while in crows the transition from black to white is abrupt).

Range, habitat, finding this species Click here for information on habitat and range The overall distribution of this species can be assessed, and specific locations where birds have been spotted can be found, based on individual sighting reports submitted by birdwatchers to ebird.org . The global distribution of the Torresian Crow is available HERE . There are two races of Torresian Crows. Together, their range encompasses eastern Indonesia, New Guinea and parts of Australia. Nominate race "orru" is found only on North Torres Strait islands and further to the North of Australia (e.g., New Guinea). The Australian mainland race of the Torresian Crow, "cecilae", is endemic to Australia. It is found mostly in the northern half of the Australian continent. Torresian Crows, race "cecilae", populate all of Cape York peninsula, QLD, and the area to the East of a line connecting roughly the southern-most tip of the Gulf of Carpentaria, Boomi, NSW, and the Hunter River estuary in NSW. Further West, Torresian Crows are found all over the NT (including offshore islands, but excluding the corner to the South-East of Alice Springs), the north-western corner of SA, the Kimberley in WA and north-western and central WA (from roughly the Gascoyne, along an about 500-km wide strip towards Kalgoorlie, WA). Torresian Crows can be found in a variety of habitats within their range, often along the fringes of forested areas, e.g. along watercourses, but also in more open country. They can also regularly be found on beaches and dunes.

Sightings Click here for sighting information Race "cecilae" Torresian Crows, race "cecilae", were first seen by us on private properties about 10 km North-West of Moree, NSW, in April 2012. There they were seen in eucalypts along the Gwydir River bordering on broadacre farmland. The contributions to these observations by C. Hayne and A. Lines (in both spotting the birds and their identification) are most gratefully acknowledged. C. Hayne and A. Lines also report that Torresian Crows, race "cecilae", are heard and seen regularly in various locations around Moree, NSW, e.g. Whittaker's Lagoon, whereas they are not always found at Narrabri, just 100 km further South, through open broadacre farming country. Torresian Crows, race "cecilae", were first positively identifed by us at Eulah Creek, 20 km East of Narrabri, NSW, in October 2012. Seen there again in October/November 2013. In October 2022 a pair was found breeding at the same location. J. Greaves reports spotting a Torresian Crow, race "cecilae", in Alyangula, Groote Eylandt, NT, in September 2014, in Broome, WA, in April 2015, and at the Granites Gold Mine, NT, in August 2015. They were also spotted at Boolardy Station, Murchison, WA, in August 2016. H. Mouritsen reports finding Torresian Crows, race "cecilae", in abundance in various locations in and around Darwin and Pine Creek, NT, in October 2015. Torresian Crows, race "cecilae", are reported to us regularly from locations in the eastern half of QLD and far north-eastern NSW. E. Scottreports finding the species breeding at Roseberry Creek Valley, near Toonumbar NP, northern NSW, in the 2017 breeding season, a nest being built in July/August. P. Brown reports finding Torresian Crows, race "cecilae", at Keep River NP, NT, in November 2018, where they were found nesting at the time, at at Tree Point Conservation Area, Shoal Bay, NT, in March 2019. M. Mearns and M. Eaton report finding Torresian Crows, race "cecilae", regularly in various locations in western QLD.
